| 摘 要： | 变截面杆件的临界载荷问题,其平衡方程为变系数微分方程,只有少部分的情况可以得到其解析解,采用改进的WBK法,计算了若干变截面压杆的临界荷载,并与有限差分法进行了对比,证实了其可靠性。

| Abstract: | The governing equation of variable cross section compressed bar is a differential equation with variable coefficients. There are some exact solutions for very few cases. Using method of modified WBK method, the critical load of some compressed bars are calculated, which are verified by finite difference method. |
