摘要
对作横向振动的转轴用能量法分为连续和离散两种模型,计算其一阶临界转速,同时将此法应用于一个实例,并进行了误差分析。
In this paper, a fundamental critieal revolution of a shaft is divided into continuum model and dispersed model by using calculation of the energy method. Moreover,the method is applied to a practical example to analyse an error in calculation.
