摘 要: 在进行多级橡胶扭转减振器中各级扭转减振器的参数设计时,需要对简谐力矩进行精确计算。探讨了曲轴轴系激励力矩的识别问题,通过自编Matlab程序,以试验中所得到的气体压力为基础,结合某国产发动机的参数,对曲轴轴系的激励力矩进行了识别,得出激励力矩各个简谐分量的幅值和相位。结果表明:发动机转速与曲轴扭转激励力矩的基频之间的比值不随转速变化而变化,与理论推导一致。 When all levels of torsional vibration damper's parameters is designed of multistage rubber torsional damper,and precise calculation of harmonic torque is needed.This paper mainly discusses the problem of crankshaft axis excitation torque identification.The Matlab program is compiled.Based on the experiment of gas pressure,and combined with parameters of a domestic engine and identification of the crankshaft axis excitation torque,it can identify different harmonic excitation torque component of the amplitude and phase.The results show that the ratio between the engine speed and fundamental frequency of crankshaft torsional excitation torque does not changes over speed,consistent with the theoretical derivation.
