摘　　要：基于国内某知名飞机装备制造公司给出的设计条件:运行速度比较低,系统转动扭矩比较大,而系统控制精度又十分高的特定工况,沿用已经存在的低速大扭矩液压马达是无法达到设计要求,本论文给出基于力士乐液压元器件的实现方法。依据系统的运动学参数,可以取得设计所需要的扭矩以及速度临界值,再据此初步选出液压元件的型号,将选定的液压元件的参数带入系统伺服函数中,用MATLAB进行建模,分析仿真结果,再微调设计参数,最终给出设计结论。Based on a well-known domestic aircraft equipment manufacturing company＇s given conditions： the speed is fairly low, the system rotational torque is relatively large, and the system control precision is very high, if we follow the existing low speed big torque hydraulic motor, it is unable to meet the design requirements. This paper gives the realization method based on Rexroth hydraulic components. According to the phoronomics parameters, we can get the critical torque and velocity, which are used for the selection of hydraulic components. After that, with the parameters of the selected hydraulic components, we build models, and analyze the results, check the difference. In the end, we make our solution.
