摘要：
The precise design of the dynamic stiffness of air spring is one of the key issues to accurately match the dynamic stiffness of the vehicle in the predevelopment stage. Considering the transition of the piston circular area, a method is proposed to get the accurate dynamic characteristics model of the air spring, which is based on the design of the piston shape in different stages according to the surface integral. The influence of the main design parameters on the dynamic characteristics of the air spring is studied. The experimental design sensitivity analysis and parameter optimization are carried out. Results show that the model can accurately predict the dynamic characteristics of the air spring and provide an economical and practical prediction method of the stiffness design of the air spring used in automobiles. When the air spring is in normal working pressure and recommended working height range, the optimization of structural parameters of the air spring piston can simultaneously take into account the comfort of vehicle itself and the comprehensive performance of the air spring and has certain economic value. © 2018, Editorial Board of Jilin University.
