Analysis on Accelerated Stresses in Reliability Enhancement Testing of Hydraulic Cylinder Leakage

  • 摘要: 在分析现有可靠性强化试验加速应力选择不足的基础上,通过对液压缸故障物理的研究,由雷诺方程推导出液压缸活塞往复运动过程中液压油薄膜的厚度,得出其漏油量与载荷和液压油压力之间的关系;通过对比分析液压缸在有无缺陷下的漏油量,证明液压缸漏油可靠性强化试验中加速应力选择的正确性;以某加工中心端齿盘分度式数控转台中的升降液压缸为例进行分析,通过选择不同水平的加速应力进行对比试验,得出其结果和用故障物理法进行可靠性强化试验加速应力分析具有一致性。
