摘要
压杆稳定欧拉公式是从纯弯曲梁的挠曲线近似微分方程EIυ″=-M(x)导出的。本文证明EIυ″=-M(x)并不适用于压杆,进而得出压杆稳定欧拉公式因出处错误而实际上并不存在的结论。
Euler's formula for stabilization of compressive bar is derived by EIV″=-M(X) from approximately differential equation of the deflection curve of pure bending of curved beam. In this paper the author has a conclusion that Euler's formula is nonexistence for stabilization of compressive bar by his certification of EIV″ =-M(X) being inapplicable to compressive bar.
