摘　　要：阐述了在四物体有摩擦弹性接触边界元法的基础上,采用轴承边界单元模拟轴承接触单元及赫兹接触理论修正滚动体与轴承内、外圈的接触宽度的轴承边界元法。轴承座采用不同受力面厚度时对轧机四列圆锥滚子轴承的径向和轴向载荷的分布进行数值模拟,得到其对四列圆锥滚子轴承载荷分布的影响规律。并通过实验说明轴承边界元法在模拟滚动轴承载荷时的正确性和有效性。The bearing boundary elements are used to simulate the bearing contact elements, the Hertz contact theory is used to re- vise the contact widths of rollers with inner race and outer race, which the Fortran program of four-body elastic contact Bearing Boundary Element Method （BEM） is complied. When different thickness of trust face of shaft block is applied to the mill four-row / conical roller bearing, the distribution of radial and axial load are simulated, with which the influence rules of thickness of shaft block to the load distribution of four-row conical roller bearing are ob- tained. The experiment proves the validity and effectiveness of u- sing Bearing BEM to solve the load distribution of bearing.
