滚动体几何相似条件在轴承边界元法中的应用
Application of geometrically similar roller conditions in bearing boundary element method
摘要
Abstract
As a multi-object contact system,roller bearing is highly non-linear.To solve its three-dimen-sional distribution of pressure and load,we establish a discrete model of the initial location roller;other rollers’discrete data can be obtained because they have geometrically similar conditions.Based on the three-dimensional,elastic contact boundary element method (BEM),all bearing rollers can be described as one object;therefore,the roller bearing problem of a multi-object contact system can be simplified to the problem of a three-object contact system.Considering the specificity of all bearing rollers described as one object,the boundary integral equation and coupling matrix equation are established.A bearing-BEM program using Fortran language is compiled based on geometrically similar roller conditions;with this method,a mill four-row tapered roller bearing is simulated.The bearing contact pressure and load,the rollers’contact widths and the number of contact rollers are obtained,certifying the method’s validity.关键词
