摘　　要：对目前用于测试车用内燃机橡胶式扭振减振器固有频率和阻尼比的衰减振动法、传递函数判别法和共振相位法作了比较试验与分析,结果表明共振相位法测试结果稳定可靠,应予推广。The rubber torsional vibration damper is widely used on internal com- bustion engine for car,the natural frequency and damping ratio of which are most important performance parameters.How to measure these parameters has been an important content of torsional vibration research all along.On the basis of testing, analyzing and comparing the traditional attenuation vibration methods such as the transfer function decision method and the resonance phase method,it is proved that the resonance phase method is better with stabie and reliable.
