Development and Application of Speed and Torque Measurement System of Pressure and Flow Compound Type Hydraulic Power Source

变转速液压驱动系统是一种新型的压力流量复合型动力源。这种动力源不仅可简化复杂的液压系统,而且还具有节能降噪的作用。介绍了用两个伺服电机对拖来模拟液压泵载荷和基于LabVIEW编写的转速转矩测试程序。通过测试程序和模拟的液压泵载荷可方便地检测变转速液压驱动系统控制性能。

The variable speed hydraulic drive system is a new kind of pressure and flow compound type power source.The com-plex structure of hydraulic system could not only be simplified by this power system,but also energy saved and noise reduced.The load of hydraulic pump simulated by two mutual-driving servo motors and the speed and torque measurement program based on LabVIEW were introduced.It is convenient to measure the control characteristic of the variable speed hydraulic drive system through the program and the simulated load of hydraulic pump.
