【摘要】：通过矩阵变换的方式对轴向加载状态下的连带轮盘弹性轴的动力学机械行为进行了研究。将传统的变换矩阵进行了修正,考虑了轴向力的作用,然后进行计算编程,进一步实现轴向载荷对悬臂转子系统稳定性和固定频率方面影响的研究。本文研究对象分为两种,一种为悬臂的自由转子系统;另一种则包含了中间支撑的影响。研究发现转子的回转效应会明显影响杆轴-轮盘系统的动力学行为,不仅会使稳态临界载荷增加,还会使失稳形态从发散转变为振颤。
[Abstract]:The dynamic mechanical behavior of the elastic axle of the wheel disk under axial loading is studied by matrix transformation. The traditional transformation matrix is modified, the effect of axial force is considered, and then the calculation programming is carried out to further realize the influence of the axial load on the stability of the cantilever system and the fixed frequency. The research object is divided into two kinds, one is the free rotor system with cantilever, the other includes the influence of the intermediate support. The study found that the rotary effect of the rotor will obviously affect the dynamic behavior of the shaft wheel disk system, which will not only increase the steady state critical load, but also change the instability form from the divergence to the vibration.
