Trumpchi GS8 Front Suspension System Design
Abstract
This article is for the design of the front independent suspension of the Trumpchi GS8 SUV. Firstly, by comparing and analyzing the structures of different independent suspensions, it is determined that the front suspension structure is a MacPherson independent suspension. Then, the overall design calculation of the main parts of the suspension is carried out, focusing on the design process of the design verification of the elastic components, the selection calculation of the damper, the calculation of the guiding mechanism and the lateral stabilizer bar. According to the design results, the 2D drawings of the parts and assembly drawings of the MacPherson independent suspension were drawn. At the same time, the dynamic three-dimensional modeling and jitter analysis of the suspension system were carried out. Finally, the front wheel positioning parameters are analyzed and tested.
