Dynamic Simulation and Modeling of Planar Revolute Joint with Clearance Based on Virtual Prototyping

The virtual prototyping modeling method of revolute joints with clearance based on ADAMS is discussed in this paper.Equivalent revolute joints with clearance are modeled with a combination of planar joint and circle-circle contact pair.Elastic impact force function is established using Hertz Contacts Theory.Viscous damper is established using a step function with a cubic polynomial.Friction model is established using a step function based on the slip speed.An example is presented which shows the dynamic simulation of a crank-rocker mechanism with revolute clearance-joints.The applicability of three common kinds of clearance-joint models is evaluated according to the simulation of the relative movement between the elements of different joints.Our results show that ADAMS is a kind of effective method for dynamic simulation of the mechanism with revolute clearance–joints.
