Abstract:
      The dynamic performance of liquid rubber composite joints for rail vehicles based on AMESim was studied.By obtaining the rubber main spring parameters and the volume stiffness，damping channel parameters and fluid property parameters of the hydraulic chamber，the dynamic stiffnesses of the rubber main spring of the liquid rubber composite joint at different frequencies were calculated，and the causes of the errors between the dynamic stiffness simulated values and experimental values were analyzed.For the dynamic stiffness amplitude-frequency characteristics of rubber materials formed by viscoelasticities，the dynamic stiffnesses of the rubber main spring were optimized，reducing the simulation errors of the dynamic stiffness to within 10% and stabilizing simulation error to within 6%.Through multivariate nonlinear fitting inversion，the amplitude-frequency data of the new structural rubber main spring could be obtained，and the simulation accuracy was relatively high.This method provided reference for the design and development of liquid rubber composite joints.
