摘　　要：为了满足烟田高架作业车道路行驶和田间行驶两种不同的行驶工况,设计了轮距调节机构。为研究轮距调节液压系统中两液压缸的同步特性,利用AMESim仿真平台建立了轮距调节液压系统的模型并依据实际作业工况进行了动力学仿真。仿真结果表明:在负载相同,负载相差100 N,负载相差500 N,负载相差1000 N这四种不同的工况下,轮距调节液压缸的位移差异最大为0.0503 m,位移的差异值在允许的范围内,轮距调节液压系统能够满足实际工作的要求,为其他车辆轮距调节机构的设计提供了参考。The tread adjustment mechanism is designed in order to adapt for the two different driving conditions about road driving and field driving of tobacco high frame field operation vehicle. The model of tread adjustment hy- draulic system is established and the dynamic simulation is finished by using the software AMESim in order to study the synchronous characteristics of two hydraulic cylinders. In the four different working conditions of same load, load difference 100 N, load difference 500 N and load difference 1000 N, the maximum displacement difference of two hydraulic cylinders is 0.0503 m, so the displacement difference is in the allowed range, tread adjustment hydraulic system can meet the requirements of practical work.
