摘 要: The crankshaft bearing in an internal combustion engine is a typical dynamically loaded bearing. In an engine, the crankshaft and bearing constitute an inseparable system. When operating, many mechanical actions in this system happen simultaneously and influence each other. This article presents a method to obtain the journal center trajectory that considers the interaction of the crankshaft and bearing. The dynamic equations of motion of the crankshaft and the Reynolds equations were solved simultaneously to determine (calculate) the load on the bearing, the dynamic response (journal center trajectory), and the tribological performance of the bearings. The numerical results show that the journal center trajectory of a crankshaft and tribological performance of bearings calculated by this method are remarkably different from those obtained by current methods.

内燃机中的曲轴轴承是一种典型的动态载荷轴承。在发动机中,曲轴与轴承构成一个不可分割的整体系统。运行过程中,该系统中的许多机械运动同时发生并相互影响。本文提出一种考虑曲轴与轴承相互作用的法向中心轨迹求解方法。通过同时求解曲轴的动力学方程和雷诺方程,可确定(计算)轴承所受的载荷、动态响应(法向中心轨迹)以及轴承的摩擦学性能。数值结果表明,采用本方法计算出的曲轴法向中心轨迹及轴承的摩擦学性能,与现有方法所得结果存在显著差异。
