摘　　要：为了研究变卷吸速度下的润滑特性,根据光干涉原理,设计出一种变速多尺度油膜测量试验机。该试验机可分为运动、支承和加载三部分。运动装置是一种曲柄滑块机构,试件由一对浮动滚子支承,载荷是通过杠杆加载在试件上。在一个试验周期内滚子的卷吸速度呈正弦变化,润滑油膜经历"弹流、薄膜和边界"的多尺度状态。利用该试验机得到的动态干涉图像可以看出变卷吸速度时有限长线接触滚子的油膜分布特征,可为研究提供可靠的试验数据。To investigate the lubrication properties under variation entrainment velocity,a set of experimental rig was designed for measuring multi-measure oil film using optical interferometry technique.This rig can be divided into moving,supporting and loading parts;moving part is crank block frame,specimen roller is supported by a pair of floating rollers,loading is done with a lever.Entrainment velocity is in the sine form variation during an experimental cycle,and it presents multi-measure lubricant film of ＂EHL,thin film and boundary＂.As a result of experiment,it can be found film distribution characteristics in dynamic interference image on finite line contacts variation entrainment velocity and provides a reliable experimental data for the investigation.
