| 摘 要： | 本文采用有限元素法的基本思想与传递矩阵法相结合，研究了非均匀弹性直梁在端部受有直簧和扭簧约束下的自振问题，给出了适合于计算机计算的最一般格式，由此出发可以导出二十多种不同边界条件下的频率方程，提出了非均匀控制变量参数，使计算工作量大为减少，且误差很小、可靠性高。

| Abstract: | The paper deals with the free vibration for non-uniform beam under the common elasticityboundary conditions based on a finite elemente method and transfering matrix method. and gives aform of simple computers which can lead-out more than twenty frequency equations. The non uniform control variable Parameter and the calculated results show their feasibility. |
