摘　　要：弹流润滑的光干涉法必须采用透明材料,而一般玻璃等透明材料不能承受高的拉应力,且局部柔性加载技术较为困难,制约着有限长线接触光弹流实验的开展。为了弥补目前对有限长线接触光弹流实验研究的不足,设计了一种三滚轮整体加载旋转工况光弹流试验机,并对滚子的弹流油膜形状进行了初步的实验。实验表明,该试验机可以有效地工作在旋转工况下,测量滚子类线接触弹流润滑接触表面的油膜形状及其变化情况,为今后相关弹流润滑成膜机理的理论研究提供有效的实验数据。Due to the fact that optical interferometry elastohydrodynamic lubrication must use transparent material,and the normal transparent material such as glass cannot work under high tensile stress. Further,the partial local-loading technique is complicated,these restrict the development of optical interferometry elastohydrodynamic experiment of finite line contact. In order to make up for the insufficient in the experimental research of optical interferometry elastohydrodynamic of finite line contact,a set of optical interferometry elastohydrodynamic experimental apparatus under rotating and whole-loading condition with three wheels was developed,and the preliminary experiment figure of elastohydrodynamic film is observed. It indicates that the new rig can efficiently measure both the figure and changing situation of the films above when under the practical rotating condition. It will provide effective experimental data for the relevant theoretical research of elastohydrodynamic lubrication.
