摘要：
The basic structure, working principle and the characteristics of large bearing capacity of hydraulic piston type inertial container are expounded, and the nonlinear mechanical model of an inertial container is established considering friction force, parasitic damping and oil elasticity effect. The mechanical performance test of the hydraulic piston inertial container is carried out on the numerical control hydraulic servo vibration table. Then, based on the test results, the parameters in the nonlinear mechanical model are identified by MATLAB parameter identification toolbox. Finally, a dynamic model of the vehicle inertial-container-spring-damper (ISD) suspension including the identified nonlinear factors is established and simulated. The results show that the root-mean-square value of the vehicle body acceleration of the vehicle ISD suspension system increases by 5%, while the root-mean-square value of the dynamic tire load and suspension working space slightly decreases, which reduces the driving comfort of the vehicle. © 2020, Editorial Department of JVMD.
