摘要
建立了活塞系统工作过程的动力学方程和油膜润滑方程,并根据实测的解放CA6102汽油机的气缸压力对活塞二阶运动进行了计算。通过分析不同情况下活塞的无量纲横向位移和无量纲横向加速度随曲轴转角的变化关系,得出了影响发动机运转噪声的实质性因素。
This article set up the dynamics equation and oil film lubrication equation of the piston system work course. And it calculated piston 2 steps according to Liberation Model CA6102 gasoline engine cylinder pressure that was measured actually. By analyzing the change relation of piston zero dimension transverse displacement and acceleration with crankshaft corner under different situations, it obtained the substantive factors influencing the running noise to strike the cylinder.
