摘要

针对变量泵-定量马达容积调速回路调速范围有限，变量泵-变量马达调速回路结构复杂的问题，故提出采用力偶型径向柱塞马达的新型恒转矩调速回路。该马达输出轴的径向力平衡，通过力偶输出转矩，马达的一个壳体内可以形成内、外两个马达；在输入压力和流量不变的情况下，通过不同的配流方式可以输出三种转矩和转速，更能满足多种工况需求；三级恒转矩调速回路在三种工作方式下产生不同的动态特性，内马达单独工作时的动态特性较好。利用AMESim软件进行仿真分析并搭建实验台对力偶型径向柱塞马达新型调速回路进行试验分析，试验数据验证了新型调速回路可增加系统的转速转矩范围，丰富了力偶型径向马达的应用领域。

Abstract

In view of the limited speed range of the volume speed control loop with a set of variable pump-quantitative motor and the complex structure of the speed control loop with a set of variable pump-variable motor, a new constant torque speed regulation loop using a force couple type radial piston motor was put forward.The radial forces on the output shaft of the motor were balanced, and the torque was output by the force couple.Two motors, one internal and one external, were formed in one motor shell.Under the condition of constant input pressure and flow rate, three kinds of torques and rotational speeds can be output through different distribution modes, which can well meet the needs of various working conditions.The three-stage constant torque speed regulating loop has different dynamic characteristics under three working modes, and the internal motor has good dynamic characteristics when it works alone.The AMESim software was used to simulate and analyze the new speed control loop using the force couple type radial motor.The results prove that the new speed control loop can increase the speed and torque range of the system and enrich the application field of the force couple type radial motor.
