摘要: 提出了一种统计线性化迭代法(IMSL)。利用这种方法,在形成非线性几何关系等效线性项的基础上,建立了非线性振动方程的等效刚度矩阵。通过求解方程,分析了几何非线性对旋转壳随机响应的影响。

Abstract: An iteration method of statistic linearization(IMSL)is presented.By this method,an equivalent linear term was formed in geometric relation and then an equivalent stiffness matrix for non-linear term in vibration equation was established.Using the method to solve the statistic linear vibration equations,the effect of geometric nonlinearity on the random response of rotational shell is obtained.
