摘要
本文导出了多缸柴油机曲轴扭振系统在考虑变惯情况下的运动方程,首次证明了该系统在不计阻尼和激励力的情况下是一个保守系统。在此基础上,阐述了国内外已有的若干工作的局限性,指出了采用非线性运动方程进行理论分析的必要性。最后给出了对单缸机模型非线性运动方程仿真结果,并与Goldsbrough的实验结果进行了比较。
Governing equations for multi-cylinder diesel crankshaft torsional vibration system with variable inertia were derived. The free vibration of this kind of system was proved to be a conservative system for the first time. It was shown that the non-linear equations should be applied to provide a good prediction of vibration amplitude occuring at unstable speed range. Finally, a one-degree non-linear equation was solved numerically and the result was compared with that of Goldsbrougn's experiment.
