摘　　要：依据某校企联合项目自装卸集装箱拖车吊装机构在作业过程中出现的不同步现象,通过对液压系统的基本结构及工作原理进行分析,找出不同步现象的原因,并提出基于PID控制的解决方案。在AMESim仿真软件中建立模型,设置参数进行仿真分析,对比有PID控制和无PID控制时液压系统伸缩液压缸的位移曲线。得出如下结论,侧偏质量越大液压系统的不同步现象越明显,引入PID控制器可极大改善自装卸集装箱拖车吊装机构的不同步现象,为解决实际工程出现的问题提供理论依据。To tackle non-synchronization occurring during operation of hoisting mechanism ot seltqOaalng aria unioaamg container trailer found in a school-enterprise joint project, the paper traces reasons of non-synchronization through analyzing basic structure and operating principle of hydraulic system and provides a PID control based solution, namely, establishing a model in AMESim simulation software, setting parameters for simulation analysis, and comparing displacement curves of telescopic hydraulic cylinder of hydraulic system with and without PID control. The paper concludes that, the greater the cornering mass, the more obvious un-synchronization is, and PID controller can greatly improve un-synchronization of hoisting mechanism for self-loading and unloading container problems in engineering practices. trailer, which provides theoretical basis for solving the
