Dynamics Simulation for Stator and Rotor Meshing of Air Drilling Motor
摘要
Abstract
In order to study the relation between structural parameters and work efficiency or useful time,a nonlinear dynamics model of a load was presented for air drilling motor.The dynamics simulation was carried out using double parameter Mooney-Rivlin model,and the effects of interference fit and eccentricity changes on the stator rubber lining＇s stress,strain and friction torque were studied with the consideration of the material nonlinearity,pressure and inertia effect of the rotor on the rubber lining.The results indicate that,the changes of interference fit and eccentricity affect the friction torque of air drilling motor and stator rubber lining＇s stress and strain,and the effect of interference fit＇s change is more obvious.Adjusting the interference fit and eccentricity can increase the work efficiency and useful time of the air drilling motor.关键词
