A Dynamic Bearing Model for Four Point Contact Bearing Analysis

摘要

A dynamic bearing model (DBM) has been developed for analysis of four point contact bearings. It can be used to calculate the contact stresses and study the dynamics of four point contact bearings used in wind turbine. DBM has been used to demonstrate the effectiveness of four point contact bearings to resist axial and moment loads. Also the motion of ball causing wear in wind turbine bearings has been simulated using DBM.
