An iteration method of statistic linea riz ation(IMSL) is presented. By this method, an equivalent linear term was formed i n geometric relation and then an equivalent stiffness matrix for nonlinear term in vibration equation was established. Using the method to solve the statistic l inear vibration equations, the effect of geometric nonlinearity on the random response of rotational shell is obtained.
