摘要
建立阻尼动力吸振器的数学模型,提出用加速度频响替代传统的放大因子作为评价指标,该指标更有利于解决振动的激励输入时的吸振器设计问题。详细分析了吸振器质量、阻尼比和频率对主系统振动后影响,并针对实车传动轴共振问题案例,分别基于放大因子和加速度频响进行动力吸振器设计比对,得以验证了模型分析的准确与有效性。
The mathematical model of damped dynamic vibration absorber was established.And the evaluation index of acceleration response replaced the amplification factor was proposed,which showed more conducive to solving damper design program with vibration excitation inputting.The effect of mass,damping ratio and frequency to the main system were detailed analyzed.Then for automotive transmission shaft resonance problem,the dynamic vibration absorbers with amplification factor and acceleration response were designed and compared,which verified the accuracy and validity of the model analysis.
