摘要
本文将文献[2]中的方法应用于转动梁的纵横弹性运动。首先建立了精确的动力方程,该方程是非线性的。接着从工程实用的观点出发,提出了一个合理的假设,从而使方程线性化,这样可较简便地求出转动体的本征值与不转动体的固有频率以及转动角速度之间的关系。
The method given in reference is applied for analyzing the longitudinal and lateral elastic motion of rotating beam in this paper.The exact equation of motion is set up at first but the equation is non-limear.A rational assumption is given for the enginee- ring purpose and,therefore,the equation is linearized based on such a assumption.The relation which shows that the eigenvalue of rotating beam is related to frequency of beam without rotation and angular velocity of rotating beam is found.
