APPLICATION OF SUB-ELEMENT AND
MICRO-ELEMENT IN
BEM WITH
ROLLER BEARING
LOAD*
Abstract: Aiming at the discontinuous traction on contact elements of roller bearing, new concepts of sub- and micro-element are put forward. In the sub-element and micro-element, traction influence coefficient has been modified, which is calculated by the former boundary element method (BEM) with roller bearing load. Hence, three-dimensional distribution of load on roller bearing is calculated accurately. In practice, it has been proved that this method has higher calculation accuracy. An effective numerical method is offered for analyzing load characteristics of roller bearing to improve service longevity of roller bearing and operation efficiency of rolling mill.
