Abstract

High-speed roller bearings are widely used in the aerospace field due to their importance. As rotating machinery develops in the areas of high speed, high precision, and high reliability, research on the dynamic performance of roller bearings is becoming more and more important. Constructing a dynamic analysis model accurately is very important in interpreting his dynamic characteristics. The basis for dynamic analysis of high-speed rolling bearings is the creation of a dynamic model of the bearing. In this paper, the method of creation dynamic analysis model of high-speed roller bearings was studied specifically. First, based on the Gupta model for high-speed roller bearings, a model was created that considered the effects of viscous resistance and oil film resistance, frictional relationship, and contact force action between the rolling element and cage. In addition, it specifically analyzed the forces and kinematic relations of each part within the rolling bearing. The dynamic model of the high-speed roller bearing was built based on the specific consideration of the factors affecting the bearing rotor system, such as load, speed, gap, friction, and resistance forces, and based on creating the dynamic equation of each part, the dynamic model of high-speed roller bearing was established.
