Study on dynamic characteristic analysis of vehicle shock absorbers based on bidirectional fluid–solid coupling

To design a high-quality vehicle shock absorber, the internal structure of piston assembly absorber is analyzed in this study. Using fluid–solid coupling method, high-precision flow grid model and solid finite element stacked valve are built analyzed. A bidirectional method proposed, which can be adopted to simulate analyze dynamic nonlinear response characteristics for slice Workbench software. The results indicate that superposition maximum occurs at inner radius, but area deformation near hole about 0.0636 mm. When stack plate just opens valve, displacement speed will simultaneously produce jump change. calculation analysis broadly line with test results, indicates accurate dependable, used study absorbers. This has important reference value optimization system
