| 摘 要： | 针对某型发动机开发实验过程中出现的拉缸现象，建立活塞一连杆组动力学模型，并进行数值仿真分析。通过一个工作循环的模拟，获得了活塞与缸套之间的接触应力及间隙、活塞在缸套中的瞬时运动特性，并与实验结果对比，找出拉缸产生的原因，为优化活塞外轮廓形线提供了理论依据。

| Abstract: | In order to analyze the scuffing of the piston in the experiment of the new engine,the dynamics model of the piston and connecting rods is established,and the numerical simulation is carried out in this paper.Through the simulation of one cycle,not only the contact force and clearance between the piston and the cylinder liner are obtained,but also the transient movement of the piston is gained.Compared with the experimental results,the numerical simulation can predict the reason of the scuffing precisely and provide a theoretical reference to the optimization of the piston profile. |
