摘要
本文应用最小余能原理的理论和方法确定变截面杆的固有频率 .具体地计算了圆锥形悬臂杆及平头圆锥悬臂杆的固有频率值 ,同时 。
In this paper, the minimum excess principle and its method are used in dynamic analysis of variable section beam. The natural frequency of taper and top plate taper beam are calculated in detail, and the effect of shearing force in beam on the natural frequency is discussed.
