摘要
本文将虚拟接触载荷法推广应用到线弹性稳态滚动接触分析。采用分布形式的虚拟接触载荷模拟滚动圆柱体与支承接触面之间的接触力，将稳态滚动的影响纳入单元刚度矩阵，导出了相应有限元方程，对二维平面应变条件下稳态滚动问题作了计算。
ln this paper, the virtual contact loading method was developed to deal withsteadily rolling contact problems considering linear elasticity and small deformation. The virtual contact loads in some distribution were used to simulate the contact forces between the rolling cylinder and baseplane. The influence of the steadily rolling on the deformation wastaken account into the element stiffness matrix and the related finite element equations wereestablished.Some steadily rolling problems under the conditions of 2-Dplane strain hadbeen solved.
