Design reviews are required for ISO 9001:2000 compliance and compatible automotive and aerospace specifications. They are becoming increasingly important in product liability litigation and are accepted as a cost-effective best practice and an effective application of knowledge management, valuable for accelerating the maturity of new products. This seminar describes how formal design reviews can improve products by uncovering potential problems before they are discovered at a later stage of development or application, when the costs of correction are much higher.

This paper presents an overview of a four-year project on integrated computational materials engineering (ICME) for third generation advanced high-strength steels (3GAHSS) development. Following a brief look at ICME as an emerging discipline within the Materials Genome Initiative, technical tasks in the ICME project will be discussed. Specific focus of the individual tasks is on multi-scale, microstructure-based material model development using state-of-the-art computational and experimental techniques, forming, assembly, design optimization, integration and technical cost modeling. The integrated approach is illustrated using a 980 grade transformation induced plasticity (TRIP) steel with a two-step quenching and partitioning (Q&P) heat treatment as an example.

The underlying theories of, both, control engineering and real-time systems engineering, assume idealized system abstractions that mutually neglect central aspects of the other discipline. Control engineering theory, on the one hand, usually assumes jitter free sampling and insignificant (constant) input-output latencies disregarding complex real-world timing effects. Real-time engineering theory, on the other hand, uses abstract performance and resource models that neglect the functional behavior, and derives worst-case situations that have little expressiveness for control functionalities in automotive systems. As a consequence, there is a lot of potential for a systematic co-engineering between both disciplines, increasing design efficiency and confidence. We have taken a standard control-engineering tool (Simulink) and combined it with state-of-the-art real-time system design and analysis tools (SymTA/S and TraceAnalyzer from Symtavision).

As requirements for protecting the global environment are being heightened on a worldwide scale in recent years, the development of fuel-economy technologies in order to reduce CO2 emissions is an important issue for the automotive industry. Aiming of improving fuel economy, TOYOTA has developed a new belt-type continuously variable transmission (CVT), unit K114, for 2.0-liter class vehicles. The CVT has adopted various technologies fuel economy such as a coaxial 2-discharge port oil pump system, wider ratio coverage, flex lock-up control,and so on. Notably, a start-stop system, which makes the engine stop automatically while the vehicle stopping with “D” range to reduce wasting the energy, is compatible with the CVT with higher quality and lower cost. In addition, the CVT has been also worked on improving quietness by adopting new soundproofing cover and by revising the arrangement of the steel belt elements in order to reduce the vibrator force which generates the belt noise.

We studied the reduction of pulley thrust and the deviation of the winding trajectory of the pushing V-belt on the pulleys to reduce friction loss due to slipping in metal pushing V-belt. Pulley thrust control, the amount of friction transmitted between the pulleys and the metal pushing V-belt, and a configuration that controls pulley inclination were three focal points in reducing transmission loss. The effects of the three methods of increasing transmission efficiency in OD ratio during cruising studied in this project were verified in tests. The new pulley thrust control employed reduced pulley thrust by approximately 40% and increased transmission efficiency by 2.6%. The trajectory of the pushing V-belt when it winds around the pulleys deviates from the theoretical winding radius due to the inclination of the pulley v-surfaces.

The framework structure of this Continuously Variable Transmissions (CVT) differs from that of previous CVT. For this CVT, we used the framework structure of our CVT for midsize cars, and changed the pulley shaft support structure and consolidated the arrangement of the hydraulic control system and hydraulic supply unit. To achieve a higher level of both starting acceleration and fuel efficiency in which the CVT is installed, we set the ratio coverage to 6.2, which represents a 14% improvement. We set the Low side ratio to the same as the previous CVT and increased the OD side ratio To ensure that the components of the fundamental framework can be mounted in vehicles with widely varying engine capacities, we designed the components to tolerate torque levels comparable to those of a 1.8 liter engine while reducing their weight by approximately 12%.

Upcoming stringent regulations on emissions and fuel efficiency are driving the automotive industry towards light-weight vehicle design. A higher share of carbon fiber composite materials in vehicle structures is expected. Current literature addresses development processes of composite components under a limited scope but the considerations of design parameters used in these studies are inadequate for the realistic development of a full vehicle structure, especially in a resource-constrained development project. In addition, existing vehicle structure design philosophies used for metallic structures cannot be directly ported over for composites design due to the differences in material properties, failure modes and design for manufacturing limitations.

This work describes the evaluation of the aerodynamic forces acting upon a road going sport motorcycle (modified for racing purposes) during a high speed, high lean angle cornering manoeuvre using commercial computational fluid dynamics software. The subject of motorcycle cornering aerodynamics is currently one not widely covered in literature. The research presented in this paper aims to provide a basis for investigations into the improvement of motorcycle cornering performance through aerodynamic modifications. Results were obtained through steady-state RANS simulation, using the k-epsilon turbulence model, of the vehicle during a cornering manoeuvre at a constant speed of 38 m/s with the lean angle varying from 45 to 55 degrees from vertical. This manoeuvre was analysed in 1 degree intervals. Large lift forces were observed, with centre of pressure located near the front of the motorcycle, which increase as the motorcycle leans further.

The need to develop products faster and to have designs which are first time right have put enormous pressure on the product development timelines, thus making Computer Aided Optimization one of the most important tool in achieving this targets. In this paper, a Design of Experiments (DOE) study is used, to gain an insight as to, how changes to different parameters of Front Suspension & Steering of a Passenger Bus affect its kinematic properties & thus to obtain an optimized design in terms of Handling parameters such as bump steer, roll steer, percent Ackerman, Lock to Lock rotation angle. The Conventional Hit & Trial method is time consuming and monotonous & still is an approximate method, whereas in Design of Experiments (DOE), a model is repeatedly run through simulations in a single setup, for various combinations of parameter settings. Effects and interactions of the design variables of the model are then studied, which provides an insight to help design an optimized model.

The main purpose of this research is to investigate the effect of volumetric efficiency of a four cylinder four stroke engine with different kinds of design parameters. There are several methods to improve the volumetric efficiency, such as changing the valve lift, the valve timing, the intake pipe parameters and setting the Helmholtz Resonator. In the research, we focus on two design parameters of intake system, adding Helmholtz Resonator and the valve timing. In Helmholtz Resonator part, we compare results of two conditions, with and without Helmholtz Resonator. Under the situation with Helmholtz Resonator, the position and the volume are also considered. And analyze the effect of the different kinds of design parameters on the volumetric efficiency. The position one of the resonator is between the gas storage tank and the air filter. There is only one intake pipe, so only one resonator is set on the pipe.

The method of analyzing the best thin-wall-tubed cross-sectional shape of impact attenuator for student formula is proposed in this study by ways of simulation and validation in any case following SAE rules. We performed using ANSYS-Explicit Dynamics method for simulation and compared the result like energy absorption among six cross-sectional shaped circle, square, hexagon, cone, square pyramid and hexagonal pyramid. The results show that at the certain deformation, the circle-shaped absorbs energy higher than others. Cone, square pyramid, hexagonal pyramid, hexagon and square can absorb the energy compare to circle as 68.5%, 53.9%, 47.8%, 30% and 1.8% respectively. We compared the result of circle cross sectional case to the quasi static experiment and found that it was in the same trend.

A vehicle of interest in this paper was a light agriculture truck operated by a 14 hp single cylinder engine. Its chassis type is a ladder frame with Hotchkiss setup suspension. In Thailand this particular truck is also called E-TAN and is mostly driven on rough terrains under agricultural applications. To improve the current design, the information on a structural strength of the truck frame is required. A combination of physical tests and computer simulations was arranged to obtain reliable predictions of stress generated in the frame under load. For the simulations, a Computer Aided Design (CAD) model of the ladder frame included a main frame and a sub frame, on which an engine and transmission system would be mounted. Leaf spring mounting brackets were modeled as well as shock absorbers mounting structures. A completed Finite Element (FE) model of the frame contains 29,730 quadratic shell elements and 34,055 nodes.

This paper investigates the way to control the fuel injection timing for diesel engine running with biofuels. The research was conducted by experiments. Two fuels, B100 and B2, were used for experiments. The engine was operated under the ESC 13 modes operation condition. In each mode, five different injection timings were tested and the associated engine performance data were recorded. During the process, the cylinder pressure variations were also captured by the pressure transducer and the pressure data were then used to calculate the indicated thermal efficiency and combustion characteristic, including the heat release rate and the crank angles from the beginning of combustion to the point that 50% of fuel was burned (CA50). By comparing the measured torque and brake thermal efficiency, the best CA50 can be determined at each operating mode.

Abstract In this study, an alternate way of development and implementation of control strategy for torque split of a Hybrid Electric Vehicle (HEV) is proposed. The control strategy evaluates each and every operating point for Internal Combustion Engine (ICE) and electric motor-generator (E-machine) corresponding to all possible torque split combinations at present time instant and finally chooses one combination with the least cost function, which is estimated by converting electrical energy into equivalent fuel consumption[2]. Henceforth, the control strategy is able to perform real time iterations to choose the E-machine and ICE torque combinations with least effective fuel consumption also referred herein to as the optimal operating points. As a result, by running the vehicle at optimal operating points, overall fuel consumption over the complete drive cycle is reduced.

Abstract This paper describes the design and development of a prototype parallel hybrid electric two-wheeler vehicle. A unique transmission system is designed, developed and integrated into a two-wheeler with conventional manual transmission system. The vehicle runs on a petrol engine coupled with an electric motor in parallel drive configuration. The vehicle has three basic modes of operation - engine mode, electric mode, hybrid switching mode. Two optional modes are also possible - Regenerative braking mode and Continuous assistance mode. Apart from these, the vehicle has an independent gear box set for the electric motor, meant for three other modes of operation - low speed (high torque), medium speed and high speed operations suitable for high gradient, city and highway conditions respectively when in electric mode. The maximum speed target in electric mode is 25kmph in city drive and 40kmph in highway with a range of 50km per charging in electric mode.

Abstract In the current competitive automobile market, with growing knowledge and concern for occupant and vulnerable road user safety, design & engineering of passenger cars in stipulated time is a challenge. As front styling is a crucial factor, early involvement of Computer Aided Engineering (CAE) through front loading helps reduce the product development time considerably with a pedestrian friendly engineered design. The present paper explains how initial inputs are given to styling & engineering teams during early stages of product development where availability of Computer Aided Design (CAD) data is minimal. Critical load paths were identified and shape of the front end was modified accordingly. Various locations of hinge mechanism were evaluated to reduce the severity of injury in the head impact zone. Sufficient gaps between the exterior surfaces and interior hard points were worked upon to reduce the impact values.

Abstract Access to Knowledge resources around the world demands special skills and calls for judicious investments. Networking is an effective tool and building networks through consortia approach is dire need of the hour. Although this approach has been used in academia, its application in industry, especially among corporate entities, is rare. This paper describes in brief an optimised way to access databases, subscriptions & memberships of different technical societies from global platforms for research & progress of Indian automotive industry. It is imperative for Indian automotive industry to enhance and strengthen its knowledge resource base, particularly in product development and manufacturing domains. This will enable the industry to achieve its mission -“AMP-2016” of becoming a hub for global auto industry. Instead of “compete and grow,” an approach of “collaborate and grow” is thought of.
