摘　　要：采用EXCITE软件对某汽油机曲轴系进行了扭振分析，计算了曲轴扭振角、飞轮转速波动以及皮带轮耗散功，计算结果显示所有参数均在规定范围内，满足使用要求。另外对双质量飞轮的共振频率进行分析，并提出了优化建议。In this paper the software excite on a gasoline engine crankshaft system torsional vibration analysis is performed, angle of torsion vibration of the crankshaft and flywheel speed fluctuations and pulley dissipation energy is calculated. Calculation results show that all parameters were acceptable to range to meet the requirements of use in the. The resonance frequency of double mass flywheel is analyzed, and the optimization suggestions are put forward.

关 键 词：曲轴 扭振角 转速波动 耗散功
