摘要
建立双层双曲扁网壳的拟壳法自由振动微分程方程,求解其自振频率与振型,编制计算程序,并通过实例计算与有限元法进行比较。本文方法手算电算均可,方法简便,计算精度能满足工程要求。
In this paper,double layer hyperboloid latticed flat shells free vibration differential equation are founded according to the method of simulated shell,and then,its frequeney and amplitude are derived.The method is compared with the finite element method.Numerical examples show that this method is simple and accarate.
