摘　　要：为提高硅油减振器匹配设计的准确性和效率,建立了柴油机曲轴系统多自由度计算模型;然后根据减振器系统工作时动态平衡的建立过程,进行轴系的扭振响应和减振器温升的计算;最后,建立优化匹配设计的数学模型,采用遗传算法,对以曲轴扭振响应的幅值、减振器工作温度和最小质量为目标进行优化求解,实现了硅油减振器的多目标的自动匹配设计的优化。柴油机台架试验证实了优化计算结果的准确性。To improve accuracy and efficiency of silicone oil damper matching design, a multi-freedom calculation model of crankshaft system was established to calculate damper temperature increment and shaft system torsional vibration response according to process of establishing the dynamic equilibrium; then set up mathematical model of the optimal matching design using genetic algorithms（GA）, realizing automatically optimal matching design of the silicone oil damper targeting crankshaft torsional vibration response amplitude, working temperature and minimum mass of the damper. Diesel engine bench test confirmed the veracity of the calculated results.
