运用二维流体动力润滑理论,建立起活塞裙部在缸套内的润滑模型,分析了活塞裙部的油膜承载力、活塞裙油膜厚度及裙部摩擦功率这3方面的综合效果,对活塞裙部进行润滑优化设计,从而阐明了中凸型活塞裙部在运转性能方面的一些优点。
The lubrication model of piston skirt in cylinder liner is established by using two-dimensional hydrodynamic lubrication theory. The comprehensive effects of the film bearing capacity of piston skirt, the film thickness of piston skirt and the frictional power of skirt are analyzed. Ministry of lubrication optimization design, thus clarifying the performance of the convex piston skirt in some of the advantages.
