活塞式发动机轴系耦合振动问题(二)——扭转、轴向的升级连振

On Coupled Vibrations of Reciprocating Engine Shaft Systems(Part 2)——Progressive Torsional-Axial Continued Vibrations

作为前文的继续,作者针对耦合振动问题进行了曲柄模型的动态试验。通过对试验结果的分析研究,揭示了扭转-轴向的升级连振现象。这种研究还有助于理解实验数据处理中出现的主要及次要因素的影响,从而提出了升级连振现象的成因,并形成了发动机轴系耦合振动问题的实际解法。

Dynamic model tests were performed as a continuation of the research described in part 1.Test records were analyzed and interpretationssought.A phenomenon of torsional-axial continued vibration,progressivein nature,was revealed.Research helps to clarify the main and sidefactors in processing the test data,the acummulation of which may formthe basis to the proposal of a rational as well as practical method ofsolution of the problem of coupled vibrations in engine shaft systems.
