The Fault Analysis and Simulation of Vehicle Hydraulic Shift System Based on AMESim

Abstract

Based on the analysis of the working principle and the failure phenomena as well as their mechanism of a particular type of tracked vehicle hydraulic shift system, a model of the hydraulic system is established using the fluid simulation software AMESim. The responses of the system are then calculated through adjusting some of the parameters of the system and inputting various fault information into the simulation model, so as to find out the correspondence between the dynamic characteristics of the system abnormity and specific component failures. It can be concluded that such simulation can serve as an easy and reliable way to analyze all kinds of fault responses in order to provide a solid reference basis for the fault diagnosis of the actual system.
