摘　　要：为了使传统速度控制回路在不增加液压元件的前提下可输出多种转速和转矩,采用了双定子泵和双定子马达作为系统的动力元件和执行元件。通过分析其新型液压回路的静态特性可知,多泵多马达速度控制回路不仅可输出多种转速和转矩,而且可实现多种恒功率和恒转矩输出,同时又实现了节能要求。为以后深入研究其他回路的动态特性和回路的设计应用提供了基础和参考。In order to enable the conventional speed control circuit to output a variety of speeds and torques without adding hydraulic components, a dual stator pump and a dual stator motor are used as the power components and actuators of the system. By analyzing the static characteristics of the new hydraulic circuit, the multi-pump multi-motor speed control loop can not only output a variety of speeds and torques, but also achieve a variety of constant power and constant torque output, while achieving energy-saving requirements. It also provide a basis and reference for further study on the dynamic characteristics of other circuits and the design and application of the circuit.
