In this paper, a model micro-car McPherson independent suspension front suspension as the research object, for some customers to reflect the type of vehicle wheel wear serious problem, ADAMS virtual prototyping software for the application platform, combined with the vehicle's simulation analysis, the process of developing the new model configuration and selection of suspension system optimization point of view of its two pairs of McPherson independent suspension system as a kinematic simulation analysis. And the optimized configuration of the micro-car McPherson suspension for vehicle simulation, which verifies the stability of the micro-car to improve handling in order to improve the selection of new products to achieve the purpose and can solve tire wear problems. This paper introduces the significance of the research projects and related research projects at home and abroad as well as development status, an overview of the general idea of this research and the main content. Then a brief introduction to the representatives of virtual prototyping software ADAMS and related theory used in this thesis, the main module, and then in ADAMS / Car environment, establish a vehicle simulation model of the various subsystems required. In the third chapter which details of the motion characteristics of the McPherson suspension on the wheel alignment parameters, resulting in abnormal wear of the wheel, and then studied from the perspective of geometry factors and the front tire wear evaluation, and finally from kinematic point of view of front wheel alignment on the impact of tire wear. Then focus on the McPherson suspension system assembly for Simulation and Optimization of parameters of its structure. Idea is to solve the front tire wear from the perspective of an exception, the focus of the front wheel alignment and tire wear between front McPherson independent suspension system and the structure was optimized. General guiding principle of this process McPherson independent suspension system is based on 9 key points as design variables, the previous round of positional parameters as the objective function, after using ADAMS software and the post-processing module PostProcessor Insi spider t module McPherson suspension system to analyze and optimize the assembly of the wheel alignment parameters, to achieve the type of suspension system performance improvements. This paper by McPherson independent suspension system and vehicle's dynamics simulation analysis, the success of the mini car was Zhendui the best selection of suspension systems solutions to significantly reduce the car's development cycle, greatly reducing new product development costs, improve product design and manufacturing quality is of great significance.
Key words: ADAMS, McPherson suspension, tire wear, simulation analysis, optimization
