活塞裙部型线研究

现代高速、高性能发动机上,活塞裙部是活塞设计中特别重要的部位。裙部形状和表面粗糙度影响着活塞裙部流体动力润滑状态（动态油膜的形成与保持）,直接影响到发动机的性能。本文在了解活塞裙部动力润滑理论及内燃机动力学的基础上,通过调试活塞裙部流体动力润滑计算Fortran源程序检验程序的正确性,并掌握活塞裙部型线设计的基本方法。

Study of Piston Skirt Profile

Pistons skirt is a particularly important part in the design of modern high-speed and high-performance engine.The shape and surface roughness of piston skirt impact the hydrodynamic lubrication state on the piston skirt(dynamic form and the maintaining of the oil film),which can impact on engine performance directly.This paper is based on the understanding of the power piston skirt lubrication theory and dynamics of the internal combustion engine.We can master a basic design method of piston skirt by commis...
