摘　　要：提出了活塞裙部摩擦润滑的数学模型，该模型考虑了裙部表面粗糙度、裙部线型对活塞润滑和摩擦的影响，所编制计算程序用于计算整个活塞横向运动轨迹，并揭示出活塞在正常工作情况下其裙部油膜力和摩擦力与曲柄转角的函数关系，给出了有关基本公式和初步结果．A mathematical model of piston skirt in lubrication is presented, considering the effects of surface roughness and piston skirt surface profile on piston motion. The corresponding computer program is developed to calculate the crosswise piston trajectory and the hydrodynamic and friction forces as a function of crank angle under running conditions. Basic equations and some preliminary results are also given.
