Abstract :
In this article, the model of damper throttle valves is established, the finite element simulation of nonlinear dynamic characteristics of damper´s valves is discussed. The solid mechanics model and the fluid dynamics model of shock absorber valves are built. By flow-structure interaction (FSI) modules from the adina software, the dynamic response is analysed in calculators, and the nonlinear characteristic of superposition throttle valves, the dynamic response of throttle slice stack and the throttle damper system flow field are obtained. This method overcomes the shortcomings of traditional modeling methods, having practical reference value to the optimal design and the analysis of shock absorber valves.
