Modeling Analysis of Shift Control System about Certain Type Armored Vehicle

针对某型装甲车辆换挡技术不够成熟和故障率高等问题,建立一种液压控制系统模型对换挡控制系统进行分析研究。根据装甲车换挡控制系统工作原理,在AMESim软件中建立其控制系统仿真模型,并结合实验数据进行校核,对油泵效率降低和调压阀阀芯卡滞2种换挡控制系统典型故障进行分析研究,通过故障分析结果与正常仿真值的对比,得出换挡控制系统在不同故障参数下对仿真结果的影响。研究结果表明:该换挡控制系统模型能够模拟实际状态下的各种故障,通过分析研究能够快速判断故障原因,并提供解决方法,为换挡控制系统故障检测和性能分析提供一定的参考。

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.
