Abstract

As a damping element between the load wheels and the vehicle body, the automobile shock absorber can effectively reduce the amplitude and frequency of vibration generated in the process of traveling, thus helping to extend the service life of elastic components and enhance the comfort of passengers. This study is based on the function and principle of automobile shock absorber, parametric analysis of automobile damping coefficients, reasonable selection of the diameter of the shock absorber working cylinder, and optimization of the design of the shock absorber piston rod, piston and other key components. Rhino software is used for three-dimensional modeling, and finite element analysis is carried out by ANSYS software to verify the performance of the shock absorber cylinder barrel. The results of the study show that the designed shock absorber has a reasonable structure and the performance meets the standard, which can effectively improve the comfort and safety of the car.
