为了研究曲轴出现裂纹时的情况，本文对整体曲轴进行了振动模态分析，分析了带皮带轮和飞轮的曲轴和单独曲轴两种情况。

During the analysis of the crankshaft with a crack, the vibration mode analysis of crankshaft which includes singularity and with flywheel and pulley has been made in this paper.

而影响内燃机整体稳定性的主要因素(限于内燃机自身)就是曲轴的旋转惯性力。

Main factor that affects internal combustion engine's stability in whole (only internal combustion engine) is crankshaft's rotation inertia force.
