本文提出了一种分析连杆轴承在动载荷作用下瞬态热弹流（TEHD）行为的数值方法。采用Newton-Raphson法和有限元法求解了气膜中的雷诺方程、能量方程和固体中的传热方程。三个区域的有限元网格是相互连接的，因此热流连续性条件是隐式的。因此，复杂结构的研究，如实际连杆轴承，可以处理和边界条件可以很容易地改变。
A numerical procedure is developed for the analysis of transient thermoelastohydrodynamic (TEHD) behavior of connecting-rod bearings under dynamic loading. The Reynolds and energy equations in the film and heat transfer equation in the solids are all solved using the Newton-Raphson method and the finite element formulation. The finite element meshes of the three domains are interconnected, and so the heat flux continuity conditions become implicit. As a consequence the study of complicated structures, such as actual connecting-rod bearings, can be handled and boundary conditions can easily be changed.
