| 摘 要： | 以机械传动中常见的变载面压杆为例，根据临界弯曲载荷相等的条件，推导出了变截面压杆在轴向压力作用下所对应的当量长度的计算公式。从而可利用材料力学中求解等截面均质压杆临界弯曲载荷的欧拉公式，求出各种不同支承形式变截面压杆折临界弯曲载荷。

| Abstract: | This paper derives the equivalent
length calculation formula for compression bar with non uniform cross section under the
condition of equalization of the critical bending loads,which are then worked out using
Euler Formula for calculating critical bending load of compression bar with uniform cross
section.A calculation example is also given. |
