【摘要】：根据加速寿命试验和并行节能技术原理,针对FAST液压促动器中故障致命度较大的元件提出并设计出一种能同时测试多个齿轮泵、溢流阀及单向阀样本的加速寿命试验台。与普通可靠性试验台相比,该试验台具有单次试验样本种类多、数量多、试验周期短及能耗低等优点。试验在多种应力等级下进行,以冲击载荷作为加速因子进行齿轮泵的冲击寿命试验及单向阀和溢流阀的加速启闭试验。文章详细介绍了试验台的总体设计方案及所采用的关键技术,该试验台的设计方法可为其他核心液压元件加速寿命试验台的设计提供参考。
[Abstract]:According to the principle of accelerated life test and parallel energy saving technology, a new type of multi-gear pump is proposed and designed for the components with high fault fatality in FAST hydraulic actuator. The accelerated life test bench of relief valve and unidirectional valve samples. Compared with the common reliability test bench, the test bench has a large number of single test samples. The test period is short and the energy consumption is low. The test is carried out under various stress levels. The impact life test of gear pump and the acceleration opening and closing test of unidirectional valve and relief valve are carried out with the impact load as the acceleration factor. The overall design scheme of the test rig and the key technology adopted are introduced in detail in this paper. The design method of the test bed can provide reference for the design of other core hydraulic components accelerated life test bench.
