摘要
采用Laplace变换研究了多个弹性支承上轴心受压的弹性失稳问题 ,推导出确定其发生弹性失稳时屈曲载荷的特征方程 。
The elastic stability of rods with pressure upon axis and multi-elastic-support was studied by Laplace's trasformation and singular function.The feature equation of bucking loads was derivated during the elastic unstableness occurring.This method was examined by calculating on practice examples.
