摘要
本文应用最小余能原理的理论和方法，对非棱柱形变截面悬臂杆进行动力分析．计算了截面几何量（截面面积和惯性矩）分别按幂函数和线性函数变化时，结构的固有频率．同时，讨论了剪力和轴向外力（压力）对固有频率的影响．
In this paper, the minimun excess principle and its method are used in dynamic analysis of non-prism beam. The natural frequency of the beam is calculated, its cross section area and inertia moment vary with power function and linear function, and effect of shear force and axes pressure on the natural frequency is discussed.
