本文建立了曲轴连杆低速大扭矩液压马达进口节流系统的数学模型。推导了低速域马达输出轴角速度随时间变化的理论解析式,采用计算机仿真手段,研究了马达自身因素及系统因素对低速稳定性的影响,通过动态仿真验证了理论分析的正确性。

This paper establishes mathematical model of meter- in system of the low speed high torque hydraulic motor with crankshaft and connecting rod, drives theoretical analytic expression of the change of angular velocity of output ahaft of the motor with the time at the low speed, and investigates the effects of factor itself of the motor and system factor of the stability at low speed. The theoretical analysis is verified by dynamic simulation.
