Modeling Analysis of Shift Control System about Certain Type Armored Vehicle

Because the shift control system is not mature with high failure rate for a certain type of armored vehicle, establish a hydraulic control system model to analyze the shift control system. Establish the system control simulation model in the AMESim based on the working principle of the armored vehicle shift control system, combining experimental data to check it, analyze 2 typical faults, such as low oil pump efficiency and the valve core binding. Comparing the fault analysis result with the normal simulation results, the influence of different parameters on the simulation results is obtained. The study results show that the model of the shift control system can simulate various faults in the actual state, quickly judgment the cause of failure and provide the solutions. It provides some reference for the fault prediction and performance analysis of shift system.
