摘要
柴油机轴系扭转振动系统是半正定的,无论是实验或计算时,均有零频响应成分,其中稳态分量称为滚振.本文讨论了零频响应的特点,给出了计算滚振参数的公式.
Zero-Frequency component is included in both the measuring and the calculating results of torsional vibration of a diesel engine shaft due to the positive-semi-definite characteristic.In this paper, the Zero-Frequency response, especially the stable part of it-rolling vibration, is studied in detail and the formula to calculate the roll coefficient is given.
