Review of Torsional Vibration Analysis of Multi-Branched Shaft Systems

复杂分支轴系的扭转振动分析方法具有重要意义。然而,复杂分支轴系扭转振动的分析方法与分析直支链式轴系扭转振动的方法有很大不同。针对复杂分支轴系的特点,国内外进行了较多的研究,提出许多处理复杂分支轴系的自由和强迫扭转振动问题的新模型和计算方法。在本文中,对这些进展进行综述并对将来的研究方向进行了讨论。

The rapid development of modern complex mechanical power transmission systems has led to an increasing interest in the analysis of torsional vibrations for multi-branch shaft systems. These systems will fail when the range of operating speed contains dangerous resonances of torsional vibration. Accurate prediction of the torsional vibration of such structures is necessary in the design stage to prevent any failure. However, the analysis method of torsional vibrations for multl-branch systems is different from that of straight shaft systems. There are many new models and methods proposed in the literature, which have been applied to both free and forced torsional vibrations of multi-branch shaft systems. In this paper, a review of these new advances is presented. The potential research concentrations are also discussed.
