摘要
为了便于解出圆筒壳的内力起见,本文提出一种求解圆筒壳内力的简易方法,它利用惯性力的分量值代替外部荷载矢量Z的法向分量。本文中推出的频谱公式便于编程电算,最后用它计算工程实例。
A simplified method used to selve internal forces in thin shell circular bin is presented in this paqer. In the method, the normal component of external force Z is replaced by a component of inertial force, ω that the vibration dynamic problem is solved as a corresponding atic way. The spectrum formulae are derived for calculation by computer. Engineering problem is demonstrated.
