Design Review Based on Failure Modes (DRBFM) is a methodology focused on change management and continuous improvement. It centers on early prevention and engineering knowledge, eliminating time spent debating ranking systems, waiting for lead engineers to document and list their concerns, identifying what types of concerns are open for discussion and resolution, and brainstorming without any actionable closure. This web seminar will explain all phases of the DRBFM methodology and provide details on how to accomplish the specific steps.

Finite Element Analysis (FEA) has been used by engineers as a design tool in new product development since the early 1990's. Until recently, most FEA applications have been limited to static analysis due to the cost and complexity of advanced types of analyses. Progress in the commercial FEA software and in computing hardware has now made it practical to use advanced types as an everyday design tool of design engineers. In addition, competitive pressures and quality requirements demand a more in-depth understanding of product behavior under real life loading conditions.

Suspension and chassis play a vital role in the structural performance of an off-road vehicle. The paper focuses on Computer Aided Engineering (CAE) modeling and simulation study of an All Terrain Vehicle (ATV) structure to analyze its static and dynamic behavior. An integrated MBD-FEA approach used for analysis purpose has been presented. In the study, a Multi Body Dynamic (MBD) model of the ATV suspension system is built using ADAMS/Car. The effect of change in suspension hardpoints on suspension characteristics has been analyzed by carrying out Design of Experiment (DOE) study using ADAMS/Insight. This is done to minimize roll, camber and kingpin angle variation during vertical wheel travel, thus increasing stability of the vehicle under rough road conditions. This helps in optimizing the front and rear suspension geometry of ATV. The Finite Element (FE) model of ATV chassis is prepared to check its structural integrity.

Pol, Ajay Virmalwar Tata Technologies Ltd., Pune, India Steve Fisher Jaguar Land Rover Ltd., Gaydon, UK SAE SIAT at India,2015 Abstract Due to increased awareness by customer perceived sound characteristics, advance simulation technique emerged in NVH domain for mid-high frequency like BEM, Hybrid and Statistical Energy Analysis (SEA). Structure-borne noise simulation primarily relies on the finite element (FE) technique and due to wide knowledge base, it is in position to get correlated results and prediction. One of the most widely and accepted practice is SEA to assess and optimize Acoustic sound pack for Air Borne Noise (ABN) in the range of 400 Hz to 10,000 Hz typically for Powertrain and Tyre Patch Noise Reduction.

Fuel economy is an important parameter which determines the position of either On-road or Off-road vehicles in the market. Earth-movers are heavy duty Off-road vehicles that are used for construction works. Currently fuel consumption in earth-movers is quantified as fuel consumed per unit time (Liters per hour). Similarly, conventional measure of productivity of the earth-movers is in terms of volume of soil trenched per hour. Measurements using the above scales showed wide variations in measured fuel consumption and productivity, • for the same equipment between measurements • two equipment of same make at different trench locations and • against the competitor equipment The reason for this variation includes the difference in soil density at different places at different depths. Thus the earth-mover in trenching operation might consume less fuel/hour and gives more productivity for the soil density being less and vice versa for the soil density being high.

Numerical Simulation of Tire and Wheel Assembly Impact Test using Finite Element Method M R Chauhan1 Prof. G N Kotwal2 A S Majage3 1,2Department of Mechanical Engineering, VIT, Pune, India 3Finite Four Technologies, Pune, India Abstract: The major concern in design of wheel is their potentiality to bear impact loads. Therefore, wheel impact test is required to fulfill the safety requirement. In this study, there are two objectives; first, the simulation of impact test for wheel is developed according to SAE wheel impact test. Often when vehicle interacts with guardrails, bridge rails and curbs the interaction between roadside hardware and wheel causes wheel damage. The test setup consists of vertically acting striker of mass 480 kg and having prescribed velocity. Energy based approach and total plastic work concept of ductile fracture mechanics is used to predict wheel impact failure.

With the increasing competition in automotive sector, the customer is available with more options when it comes to buying a vehicle. So it has become necessary to improve the vehicle’s characteristics which affect its impression on the customer. Handling and ride comfort are very important characteristics that influence the quality of the vehicle. These characteristics depend on the suspension system of the vehicle. The three main objectives that a suspension system of an automobile must satisfy are ride comfort, vehicle handling and suspension working space. Ride comfort is directly related to the vehicle acceleration experienced by the driver and the passengers. Higher vertical acceleration, lesser is the level of comfort. The aim of this paper is to design and analyze the semi active suspension system models using skyhook, ground hook and hybrid control method.

There is a growing need for improved conceptual vehicle designs along with alternative materials to reduce the damage to the passengers and structures in aerospace and automotive industries. The energy absorption characteristics of materials play a major role in designing a safe vehicle for transport. In this paper, compression behavior and energy absorption of aluminum alloy AA6061 and AA7005 tubes in T4 and T6 conditions are investigated by experimental and numerical methods. The AA7005 and AA6061 tubes are solution heat treated and then aged to achieve the final strength in T6 condition. Experimental compression test results have shown improved energy absorption of tubes in T6 condition compared to tubes in T4 condition. There is less variation of energy among the tested samples. The mean load is compared with the results obtained from analytical formulas. Tensile properties have been obtained from tensile tests using UTM for both AA6061 and AA7005 tubes.

Dynamic Analysis of Outside rear view mirror of a car S. W. Thor1, S. P. Chippa1*, A. S. Majage2 1Department of Mechanical Engineering, Vishwakarma Institute of Technology, Pune 2Finite Four Technologies, Pune *Correspondence author : chippashriniwas@gmail.com Abstract:- An Automobile rear view mirror is attached at the side of the vehicle which is used to provide clear vision outside the vehicle. In the running condition of vehicle, various vibrations occur and are transferred to the mirror which may disturb driver's rear view. Since this issue is related to safety consideration, it becomes essential to minimize the vibration of mirror. Vibration analysis is very much important for the successful design and development of new parts in automobile. In present work, Vibration analysis of existing design of outside rear view mirror is investigated through numerical model using FEM. Furthermore, these results are verified through experimental work.

Special purpose, high payload carrying capacity, live gooseneck, multi axles, hydraulic suspension semi trailer is ab-initio designed for transportation and tilting of heavy cargo from horizontal to vertical by hydraulically actuated mechanism integrated on the trailer. The chassis is levelled on hydraulic jacks followed by tilting of cargo. Hence the chassis experiences variable forces during tilting and estimated from kinematic model of tilting mechanism. These forces are input for finite element based structural design of chassis. Structural deflection of a step is made as initial condition for certain load cases of the analysis. Live gooseneck of this semi-trailer consists of hydraulically actuated mechanism, interconnected with multiple hydraulic suspensions in appropriate ratios. Estimation of Axles and fifth wheel force distributions of such trailer is complex. Mathematical modelling made to estimate these forces and applied as inputs for finite element analysis.
