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.

Abstract Studies have shown that the number of road accidents caused by rollover both in Europe and in Turkey is increasing [1]. Therefore, rollover related accidents became the new target of the studies in the field of vehicle dynamics research aiming for both active and passive safety systems. This paper presents a method for optimizing the rear suspension geometry using design of experiment and multibody simulation in order to reduce the risk of rollover. One of the major differences of this study from previous work is that it includes statistical Taguchi method in order to increase the safety margin. Other difference of this study from literature is that it includes all design tools such as model validation, optimization and full vehicle handling and ride comfort tests. Rollover angle of the vehicle was selected as the cost function in the optimization algorithm that also contains roll stiffness and height of the roll center.

As an effective approach for the design, implementation and testing of control systems, hardware-in-the-loop (HIL) testing has been used in many research areas. This paper describes a real-time HIL simulation test for the automotive electronic control system. The HIL system proposed in this paper consists of three parts: real-time target hardware, electronic control unit (ECU) of automotive electronic control systems and signal-conditioning unit which regulates the voltage levels between real-time target and ECU. The HIL simulation evaluates the mechanical and electronic behaviors in real time using off-line simulation models by interfacing real-target with electrical control units via interface box. The model was developed by MATLAB/Simulink. The model is composed of mechanical part which predicts dynamic behaviors and electronic part to calculate the motor speeds, current and electronic loads under the various conditions.

The Global Positioning System (GPS) has gained increasing popularity in recent years, as it is widely used in navigation, mapping, radar motion compensation and other related fields due to the high accuracy of 3D positioning and speed information for all kinds of users. As for the field of intelligent vehicle, the measurement accuracy and error model of GPS are needed to be known in order to ensure the credible results in the virtual simulation environment for Advanced Driver Assistance System (ADAS) and active safety technologies. Thus, it is important to establish the correct GPS observation error model when applicable. The simulation of GPS observed values and GPS positioning are both interrelated and different, for GPS positioning is used to determine the 3D position of the observed GPS signal in a certain position, and the simulation of GPS observed values attempts to restore the GPS signal which can be observed by using the 3D position that is already known.

The evaluation of perceived comfort inside a car, in the early stages of design process, is still an open issue. Modern instruments like CAE (Computer Aided Engineering) and DHM (Digital Human Modeling) already offer several tools for a preventive evaluation of ergonomics parameters for car drivers through the use of detailed CAD (Computer Aided Design) models of car-interiors and by the multi-body approach for evaluating movements and interactions. Nevertheless, it is not enough because the subjectivity of comfort perception is due to parameters that are very difficult to be evaluated in the early stage of design and need “hard-prototypes” that, often, are too expensive to be realized. In the latest 30 years, several researchers tried to develop methods to objectivize the comfort performance but most of them are based on questionnaires, marketing researches, physiological and biomechanical analyses, and need devices or interactions that modify the perceived comfort.

A new beam element is developed, which is capable of capturing thin-walled beam’s collapse mechanisms under dynamic load such as impact load. Such beam element can be used to create simplified finite element models for crashworthiness analysis and simulation and, therefore, will significantly reduce the modeling effort and computing time. The formulation of the developed beam element has been implemented into the User Defined Element Interface of LS-DYNA and used for creating a simplified thin-walled beam model. In the future, the new beam element will be used for crashworthiness analysis for further validation.

This paper presents a methodology for the assessment of the NVH performance of a DCT depending on some transmission design parameters, e.g. torsional backlash in the synchronizers, clutch disk moment of inertia, etc., during low vehicle speed maneuvers. Firstly, a 21-DOFs nonlinear dynamic model of a C-segment passenger car equipped with a DDCT is presented. From the torsional variables computed during simulation, the forces at the bearings that support the transmission shafts are calculated; both the axial and radial component of each bearing force are estimated through the model. It has been noted that an impact between the teeth of two engaging rotating components, e.g. gears and synchronizers, corresponds to an impulse in the simulated forces, which leads to a bearing force time-history characterized by a very rich frequency content. A broad band excitation is therefore applied to the gearbox case thus generating noise and vibration issues.

A steady increasing share and complexity of automotive software is a huge challenge for quality management during software development and in-use phases. In cases of faults occurring in customer’s use, warranty leads to product recalls which are typically associated with high costs. To avoid software faults efficiently, quality management and enhanced development processes have to be realised by the introduction of specific analysis methods and Key Process/Performance Indicators (KPIs) to enable objective quality evaluations as soon as possible during product development process. The paper introduces the application of specific analysis methods by using KPIs and discusses their potential for automotive software quality improvement. The aim is to support quality evaluation and risk-analysis for the release process of automotive software.

Fixtures play a key role in locating workpieces to manufacture high quality products within many processes of the product lifecycle. Inaccuracies in workpiece location lead to errors in position and orientation of machined features on the workpiece, and strongly affect the assemblability and the final quality of the product. The accurate positioning of workpiece on a fixture is influenced by rigid body displacements and rotations of the workpiece. In this paper, a systematic approach is introduced to investigate the located workpiece position errors. A new mathematical formulation of fixture locators modeling is proposed to establish the relationship between the workpiece position error and its sources. Based on the proposed method, the final locating errors of the workpiece can be accurately estimated by relating them to the specific dimensional and geometric errors or tolerances of the workpiece and the related locators.

One of the most important characteristics of industrial products, especially mechanical set-ups, is considering the tolerances of production and assembly of these set-ups, which it directly influences the products’ operations. In sheet metal structures, due to the high flexibility of the sheets, the errors appeared while assembly will be as highly influential as the errors due to the production tolerance of the sheets. As a result, having a comprehensive model which could analyze the assembly process of these structures and also clarifies the relation between the tolerance of the parts and the ultimate changes of the set-up will be of considerable importance. During the assembly process, the contact effect between the components is inevitable. If such effect is not considered, the contact surfaces will permeate. The purpose of this paper is to present a method to analyze the tolerance of flexible sheet structures, considering the contact effect between surfaces.

For vehicle thermoelectric generator, heat would been directly transferred into electricity by thermoelectric modules because there was temperature difference between heat exchanger and water tank. The electrical power generation was deeply influenced by temperature difference ,temperature uniformity and topological structure of TEG. In previous works, increasing the difference of temperature would significantly enhance the power generation of TEG and inserted fins were always applied to enhance heat transfer in parallel-plate heat exchanger. But fins would result in a large backpressure which was not conductive to efficiency of the engine. In current study, to enhance heat transfer rates and outside surface temperature, cylindrical grooves on the top and bottom surface in heat exchanger was proposed .The groove geometries were cylindrical grooves with rounded transitions to the adjacent flat surfaces.

With increasingly stringent light duty particulate emissions regulations, it is of great interest to better understand the events leading to particulate matter formation. Building a thorough understanding of particulate matter formation is an essential step in developing effective control strategies. It is especially important to do this in such a way as to emulate real driving behaviors, including cold starts and transients. In this study, it was desired to realistically examine the evolution of the particulate emissions during transient operation in a recent model year vehicle equipped with a GDI engine. Three of the major federal test cycles were selected as evaluation schemes: the FTP, the HWFET, and the US06. These cycles capture much of the driving behaviors likely to be observed in typical driving scenarios. Measurements included particle size distributions from a TSI EEPS fast-response particle spectrometer, as well as real-time soot emissions from an AVL MSS soot sensor.
