针对传统液压元件可靠性试验耗时长、能耗高、测试效率低的缺点,提出了一种液压元件并行节能型可靠性试验方法,还介绍了此并行节能型可靠性试验装置的设计原则和要求。通过增加单次可靠性试验的样本种类和数量,可以有效缩短试验时间,并对能源进行多次循环利用。试验结果表明,并行节能型可靠性试验台的功率损耗得到大幅下降,具有较大的应用推广价值。 Aiming at the disadvantages of traditional hydraulic components reliability testing, such as long time consuming, high energy consumption and low test efficiency, a parallel energy-saving reliability test method for hydraulic components is proposed. The design principles and requirements of this parallel energy-saving reliability test device are also introduced . By increasing the number and type of samples in a single reliability test, the test time can be effectively shortened and the energy can be recycled many times. The test results show that the parallel energy-saving reliability test bench power loss has dropped significantly, with greater application value.
