摘要：The article introduces a general solution for dynamic analysis of a planar multibody system with revolute lubricated clear?ance joint. An improved transition force model is established, which includes dry contact force and hydrodynamic forces, accounts for not only squeeze-film effects but also wedge-film effects, and is applicable to both long and short bearings. Then, the dynamic behaviors are presented based on this transition force model and a planar slider-crank mechanism with a lubricated revolute clearance joint. Different test conditions are considered in order to present a parametric study about the effects of clearance size, crank speed, and lubricant viscosity on the dynamic characteristics of planar multibody system with lubricated revolute clearance joint. As shown by numerical simulation results, it can be included that with larger clearance size and crank speed, as well as smaller lubricant viscosity, the system has higher vibration amplitude and lower minimum film thickness.
