摘要： 具有一定润滑条件的弹性连杆机构，其运动副之间的油膜力对机构的动态响应有一定的影响。根据三维Reynolds方程及Sommerfield条件，考虑油膜厚度变化产生的油膜挤压效果，建立计入油膜刚度特性的弹性连杆机构分析模型。并对连杆两端点处运动副油膜扰动力及相对轴线轨迹进行了实验研究和理论分析。

Abstract: The oil film disturbing force between pairs has their effection on the dynamic strain responses of the elastic linkage with a proper lubrication condition. In this paper, based on the three dimensional Reynolds equation and Sommerfield condition, with considering variation of oil film depth and its effection on the extrusion, the analytical model of elastic four-bar linkage mechanisms has been set up.

Key words: 刚度, 连杆机构, 油膜, 运动副
