Influence of Contraction Amount on the Analysis of Static and Dynamic Characteristics of Automobile Suspension Bushings
摘要
Abstract
In order to effectively carry out the simulation research for the handling and riding performance of the vehicles, it is necessary to accurately design and control the static and dynamic stiffness ranges of the automotive suspension bushings. In this paper, the hyper-viscoelastic finite element model of a rubber bushing for an automotive suspension shock absorber is established using the 3rd order Ogden hyperelastic constitutive model and the 3 rd order PRONY series viscoelastic model. The finite element analysis module ABAQUS/Standard is used to study the relationship between the radial contraction amount and the static and dynamic stiffness. The static and dynamic stiffness curves of the rubber bushings vs. different contraction amount are obtained. The results show that when the contraction amount is less than 0.6 mm, the static and dynamic stiffness of the rubber bushing increases almost linearly with the increase of the contraction amount. When the contraction amount is greater than 0.6 mm, the static and dynamic stiffness increases rapidly with the increase of the contraction amount. When the contraction amount reaches a certain level, its influence on the static and dynamic stiffness values of the rubber bushing becomes larger. Finally, the experimental results show that the relative error between the finite element analysis results and the test results is less than 10 ％. Thus, the correctness of the static and dynamic characteristics analysis of the automotive suspension bushings considering the influence of the contraction amount is proved. This study has a certain guiding significance for the design and analysis of rubber bushings for vehicles.关键词
