The Three-Dimensional Design And Motion Analysis Of McPherson Suspension

Vehicle suspension system is the center assembly of automobile chassis, which largely determines vehicle handling stability and ride comfort.McPherson suspension has many advantages, such as a simple structure, low cost, space-saving, is the most widely used independent suspension system.The paper takes a car's McPherson suspension system as a reference object, and establishes the three-dimensional model of McPherson suspension by PRO/E software, takes the kinematic emulation analysis application of McPherson Suspension by ADAMS software,analysis the characteristic of McPherson suspension's positional parameters in the process of bobbing,find out the problems of suspension, and then further analysis the affect of positional parameters when change the coordinate of suspension some key points in a series of experiments using ADAMS. Last, the paper obtain the hard point coordinates after taking the optimize the hard point coordinate of McPherson suspension on the basis of the above research the method is a good solution. This article is divided into five chapters, the following chief content:Firstly, this paper described the purpose and significance of paper, introduced the suspension system classification, reviewed the current status of foreign and domestic suspension systems and then the McPherson suspension system for a detailed introduction, summarizes the structural features of McPherson suspension system. Secondly, paper take the kinematics of suspension to study McPherson suspension, and introduced factors of kinematics, and how these factors affect the characteristics of suspension system. Then it introduced the important and difficult of the designing of McPherson suspension, which paved the way for further work. Next, it described the modeling ideas, processes and details of McPherson suspension system in detail, and then created McPherson suspension geometry model and physical model, building the simulation model of Macpherson. I found out the problems in the design through the simulation analysis, which paved the way for further work.It carried out a series of experiments on several key points to optimize suspension using the actual method for the problems of McPherson suspension, it obtained the optimization solution and solved the problems.In summary, the main advantage of this article was that the parameters of the optimized kinematics have been greatly improved, which track changes to improve significantly, improving the car's handling and stability, and reducing tire wear. The research methods used in this paper is close to suspension designing, which made a useful exploration...
