赫兹接触理论, 弹性接触, 边界元法, 滚动轴承

A revises method was proposed herein,which was used to analyze mill roller bearing load with boundary element method. First, a contact width was supposed, then the Hertz contact theory was used to revise the contact width.By means of the iterative algorithm, the calculation prosess will stop until the D-value of supposed contact width and the revised contact width satisfy the convergence conditions, with which a more accurate result can be obtained. An example of a conical bearing system of one duo mill was given to show the effectiveness and high accuracy of the theory. 
