滚动直线导轨副寿命试验台设计与试验方法研究的中期报告 摘要： 本文介绍了滚动直线导轨副（RG）寿命试验台的设计和试验方法。采用了响应面法和模拟试验优化方法设计RG试验台，并进行了试验验证。通过使用自制的试验台，在不同负载下对RG进行试验，以验证其寿命和工作性能。试验结果表明，RG寿命试验台具备较高的试验效率和精确度，能够为RG寿命和工作性能的研究提供重要参考。 关键词：滚动直线导轨副；寿命试验台；响应面法；模拟试验优化 Abstract: Thispaperpresentsthedesignandtestingmethodsofarollinglinearguide(RG)lifetestbench.TheresponsesurfacemethodandsimulationtestoptimizationmethodwereusedtodesigntheRGtestbenchandexperimentalverificationwasperformed.Byusingaself-madetestbench,theRGwastestedatdifferentloadstoverifyitslifeandworkperformance.ThetestresultsshowthattheRGlifetestbenchhashightestefficiencyandaccuracy,andcanprovideimportantreferenceforthestudyofthelifeandworkperformanceoftheRG.
