Dynamic Analysis and Experimental Study on Crank Slider Mechanism with Flexible Connecting Rod
In order to study the influence of the flexible connecting rod and hinge contact pair with solid lubrication coating MoS2 on the dynamic characteristics of the hinge mechanism with clearance,the crank slider mechanism was taken as the research object,and Adams software was used for numerical simulation analysis.The influences of the flexible connecting rod material,hinge clearance,hinge contact pair material and solid lubrication coating on the surface of hinge contact pair on the dynamic characteristics of crank slider mechanism were studied.By setting up a crank slide test bench with clearance hinge,which is consistent with the numerical simulation parameters,the test proves that the vibration of the mechanism can be reduced by the flexible connecting rod,the smaller clearance value and the contact pair material with smaller contact stiffness,and the coated hinge can effectively reduce the wear of the contact surface.The experimental results are consistent with the numerical simulation results,which can effectively reflect the influence rule of the various working conditions on the mechanism with clearance,and provide theoretical basis and experimental basis for studying the solid lubrication coating in the aerospace field on the damping and impact resistance of the mechanism with clearance hinge contact pair.
