Finite Element Analysis of Equivalent Stiffness for Throttle Slices of Shock Absorbers
摘要
Abstract
To efficiently and accurately obtain the stiffness characteristics of throttle slice groups of shock absorbers, the finite element analysis models considering and without considering the fluid-structure coupling effect were established respectively by means of commercial finite element software. By solving the models and extracting the stiffness characteristics of the throttle slices, it was found that when there is no slot in the throttle slices and valve seat and the valve deformation is small, the fluid-structure coupling effect does not need to be considered in solving for the stiffness characteristics of the throttle slices; otherwise, the fluid-structure coupling effect must be considered. Applying different fluid velocity to the fluid- structure coupling model, it was found that in the condition of rapid incentive and large deformation, the fluid-structure interaction should be considered in model establishment. The greater speed of the throttle slice deformation will cause the weaker stiffness performance of the throttle slices. To test and verify the reliability of the above conclusions, the performance simulation model of a type of gas-precharged dual-sleeve shock absorber was established. By comparing the simulation results with test results, the conclusions above were proved to be correct and credible.关键词
