摘要
采用摄动法研究了楔形杆轴固有纵扭振动,推导出了其固有纵扭振动的振型函数及频率特征方程。实例表明,该摄动法不仅计算简便,而且计算精度与Bessel函数解相当。
With perturbation method, the torsion vibration of wedge-shaped shaft is studied, and both the vibration mode function and frequency eigen function are derived. The examples show that the perturbation method is not only simple but as precise as the Bessel method.
