通过定义接触面滑动屈服函数和流动势函数,得出了热接触边界的互补方程.基于虚功原理和接触单元技术,推导了热应力作用下三维弹性接触问题的有限元方程,在该方程中引入了接触伪荷载,以反映接触状态变化对荷栽项的影响.在遮代求解过程中采取每作两次迭代进行一次加速的策略,显著提高了求解效率.

By defining the sliding yield function and the flow potential function of the contact surface, the complementary equation of the thermal contact boundary is obtained. Based on the principle of virtual work and the contact element technology, the finite element equation of the three-dimensional elastic contact problem under thermal stress is derived, and the contact pseudo-load is introduced into the equation to reflect the influence of the contact state change on the load planting. In the process of shading solving, the strategy of accelerating every two iterations is adopted, which significantly improves the solution efficiency.
