摘要
在进行动力负载试验时,由于被试样品和试验系统并不对外做有效功,采用功率消耗的加载方式,造成能源的极大浪费。通过研究机械循环和液压循环功率回收的原理,分析功率回收液压系统的加载方式和功率回收影响因素,建立起功率回收型扭矩试验液压系统,采用功率回收加载代替功率消耗加载进行扭矩试验,可简化系统结构,并能扩展应用于输出转矩的验证试验和传动机构的抗扭试验。实验表明该试验系统可有效降低试验过程中的功率消耗。
In the dynamic load test, because tested sample and testing system do no external work, there will be a great waste of energy to adopt the loading of energy consumption. By the study on the theory of energy recovery based both on mechanicM circulation and hydraulic circulation, it analyzes the loading methods of hydraulic system for energy recovery and the factors affecting the energy recycling rate, and also establishes a hydraulic torque testing system of energy recovery, adopting the energy recovery for the torque experiment instead of energy consumption, thus to simplify the system structure and expand the range of application for both proof test of output torque and anti-torque test of driving mechanism It has been proven that this testing system can effectively decrease the energy consumption during test.
