摘　　要：在考虑车厢的惯性力和惯性矩的情况下,导出了作用于自装卸机构吊钩的作用力的计算公式。基于功率键合图理论,建立了自装卸机构液压系统的仿真模型,进行了数字仿真计算,得出了相应变量的瞬态响应值。The automatic with the consideration of the inertial force and the moment of inertia, the calculation formulas of the force acted on the hook of the loading arm were derived. The mathematical model of the hydraulic system of the automatic loading device was established based on the theory of the power bond graph. The dynamic characteristics of the hydraulic system were simulated numerically, and some significant results were presented.
