Abstract In this paper, we present a design and control methodology of an innovated structure of switching synchronous motor. This control strategy is based on the pulse width modulation technique imposing currents sum of a continuous value and a value having a shape varying in phase opposition with respect to the variation of the inductances. This control technology can greatly reduce vibration of the entire system due to the strong fluctuation of the torque developed by the engine, generally characterizing switching synchronous motors. A systemic design and modelling program is developed. This program is validated following the implementation and the simulation of the control model in the simulation environment Matlab-Simulink. Simulation results are with good scientific level and encourage subsequently the industrialization of the global system.

Gas Metal Arc Welding (GMAW) technology, as one of the most popular welding methods is widely used for joining relatively thick sheet steels of body-in-white structures and frames in the ground vehicle industry. It is very flexible for welding various joint geometries with high welding speed. However, fatigue failures most likely to occur at the welded joints subjected to various types of loads due to the inherences of the welded joint, which will result in the degradation of structural and noise performance. So a reliable fatigue life assessment method is needed for vehicle design and analysis engineers to avoid time consuming fatigue tests. Recently, structural stress methods are becoming commonly employed in fatigue life prediction of welded structures due to their less mesh sensitivity compared to conventional stress methods. The structural stresses are usually recovered from the nodal force/moment calculated by finite element analysis (FEA).

EPP foams are most commonly used in automotive applications for pedestrian protection and to meet low speed bumper regulatory requirements. In today’s automotive world the design of vehicles are predominantly driven by CAE. This makes it necessary to have validated material model for EPP foams in order to simulate and predict performance under various loading conditions. Since most of the automotive OEMs depend on local material suppliers for their global vehicle applications it is necessary to understand the variation in mechanical properties of the EPP foams and their effect on performance predictions. In this paper, EPP foams from three suppliers across global regions are characterized to study the inter-supplier variation in mechanical properties. In order to understand the effect of inter-supplier variation on vehicle performance, LSDYNA rate dependent material model is developed and validated for low speed and pedestrian protection load cases.

The paper uses the body of a low-speed electric vehicle as the research object. Firstly, the paper extracts the load time history about the junction between the body and the suspension in the way of multi-body dynamics simulation by establishing the multi-body dynamics model of the whole vehicle and simulating the condition where the fully loaded vehicle travels in B level road at 30 km/h. Secondly, the paper processes the load time history to obtain the amplitude-frequency characteristic by Fourier transformation. Thirdly, the paper analyzes the modal of body to obtain its natural frequency. As the natural frequency of the body is less than the excitation frequency at which the suspension affects the body, the paper calculates the stress time history in quasi-static method. Then the paper counts the stress time history in rain-flow method, adjusts the average of the stress according to Goodman Curve and accumulates the damage of body based on Miner’s rule.

In urban driving conditions, the steering vibration feel plays a major role with the customer spending a significant amount of time behind the steering wheel. Considering the urban drive at Indian roads, 1000~1500rpm band becomes primary area of concern. In this paper, study has been conducted to define the target areas as well as its achievement in reference to given driving pattern on a Front Wheel Powered Passenger car for steering vibration feel. During the concept stage of vehicle development, a target characteristic of steering wheel vibration was defined based on the competitor model benchmarking and prior development experience. A correlated CAE model was prepared to evaluate the modification prior to prototype building and verification. Vibration level in all 3 degrees of freedom at the steering wheel location was measured in the initial vehicle prototypes and target areas of improvement identified.

The application of induction hardening treatment plays a vital role for enhancing fatigue life of various automotive components. This will incorporate compressive residual stresses in the component at significant extent. In this paper, wide range of experiments have been carried out on Rotating Bending Fatigue (RBF) specimens made from 38MnVS6 micro alloyed steel with induction hardening up to three different case depths. The set of specimens are fatigue tested at fully reverse loading condition using rotating bending fatigue testing machine. Based on this study a surface treatment factor is evaluated. This surface treatment factor is used as an input for evaluating precise fatigue life of the specimen using FEA packages. The fatigue life evaluated using FEA is showing good agreement with the results obtained through tests on the actual specimens.
