摘要
活塞二阶运动的动能反映了活塞敲击缸套的剧烈程度。本文用AVL Excite对活塞二阶运动的动能进行计算。采用二次回归正交试验设计中的方差分析,对配缸间隙、活塞销偏置、连杆长度等结构参数对活塞撞击能量的影响关系进行分析。结果表明:对活塞敲击能量影响最大的是配缸间隙,其次是连杆长度,影响最小的是活塞销偏置。以上结果对活塞的进一步优化提供了参考。
The piston＇ s kinetic energy of second order motion reflect the intensity of piston knocking the cylinder liner. In this paper, the piston＇ s kinetic energy of second order motion is calculated with AVL Excite. Take the variance analysis used in the quadratic regression orthogonal experimental design to analyze the cylinder clearance, polarization of the piston pin, the influence of the structure parameter of connecting rod length on the strike energy of the piston. The analysis results shows, that cylinder clearance is the largest impact on knocking energy to piston, the connecting rod length is in the second place and the polarization of the piston pin is the smallest impact. The results above provide reference for further optimization for piston.
