含间隙多体系统销轴磨损动力学仿真研究
Dynamics Simulation of Wear in Revolute Clearance Joints of Multibody Systems
摘要
Abstract
In order to predict the trend of joint wear,and the result was applied to the wear can accurately make the dynamics simulation and calculation,based on the dynamic model for slider-crank mechanism with clearance,considering the contact journal and bear interface curvature radius in the process of change trend,a basis for calculating the radius of curvature of contact width change extrapolation wear simulation model is established,and with the calculated results,the wear dynamics change of mechanism is simulated,the stress distribution and the wear rules and dynamic characteristics of pin shaft under different load are gotten,the laws of the function of system degradation is found.关键词
