Abstract
The vibration problem of hydraulic system is related to the normal operation of vehicles. The research methods of hydraulic system mainly include finite element simulation and vibration test. The vibration test is not repeatable because of the great influence of the environment, and the computer simulation provides the possibility for the analysis of the complex hydraulic system. However, in the process of local refinement design of the system, the simulation calculation of the whole structure is still needed to modify the local parameters, and the simulation time is long. Based on the substructure method in structural analysis, the substructure method for fluid structure coupling is derived to reduce the time cost in the simulation process of hydraulic system. In this paper, pointing at the particular vibration region of the pipeline, the structure is divided into substructures. The dynamic characteristics of each substructure are obtained by dynamic analysis, and the overall characteristics of the system are obtained according to the boundary coordination.
