提出一种新的液压试验台模式：综合模式，能够实现能量回收模式和常规模式两种模式下双向变量液压泵、马达的性能测试，充分发挥能量回收模式和普通模式的互补作用，实现较小功率的恒压变量泵驱动较大功率被测泵、马达，还可以用常规模式来解决能量回收模式下测试功能不全、流量无法计量等问题。该试验台中，以往能量回收模式下系统压力变化过快、压力脉动大、被测泵和驱动马达流量不匹配等问题被优化，压力调节调节精度高、范围较广，节能效果和系统响应都明显增强。以具体的检测实例来说明该试验台工作原理和创新之处，在常规模式和能量回收模式下分别对被测泵输出压力进行检测和对比，系统运行稳定可靠，达到了预期的设计要求。

A new type of hydraulic test?bed mode was proposed. The test?bed was integrated, which was able to achieve bidirec?tional variable displacement hydraulic pump, motor performance tests in both energy recovery mode and regular mode. By fully using the power saving mode and the normal mode complementarity, the low?power pump was used to drive high?power pump. Also by using the conventional mode, the issues were solved as test dysfunction, unable to measure output flow and others under the energy recovery mode. In the test?bed, the issues were optimized as the too quick pressure changing, big pulsation, tested pump and drive motor flow not matched under the previous energy recovery mode, pressure regulators were regulated with high precision and wider range, and en?ergy efficiency and system response were all significantly enhanced. Respectively the tested pump output pressure were tested and com?pared in the normal mode and energy recovery mode, by using the detection of specific examples to illustrate the working principle and innovation. Experimental data show that the system operation is stable and reliable, the desired design requirements are achieved.
