Abstract
- To research the dynamic response characteristics of the multi-link complex mechanism with lubricated clearance joint, an improved transitional lubrication model considering the roughness of the contact surface is established based on the fuzzy set model of the lubrication state. The dynamic model of a six-bar rocking feeding mechanism with lubricated clearance joint is established, and the influence of dry friction clearance and lubricated clearance on the dynamic response of the mechanism are analyzed. By comparing with the simulation results of ADAMS and Flores lubrication model, the correctness and effectiveness of the established dynamic model and the improved transition lubrication model are verified. The influence of driving speed, clearance size and number of clearances on the dynamic response of the mechanism with lubricated clearance joint is mainly studied. The simulation results show that the driving speed, clearance size and number of clearances have an impact on the dynamic characteristics of the mechanism. With the increase of driving speed and clearance value, the greater the impact on the mechanism, the increase in the number of clearances, which reduces the stability of the mechanism, and there is interaction between different clearance joints.
