摘　　要：针对细长体结构,在采用辅助支撑系统及不采用辅助支撑系统情况下,应用有限元方法,分别进行了随机振动响应计算,并对比了两种情况下结构响应的差别,分析了辅助支撑系统对结构振动响应分布的影响。The random vibration responses of slender structure with and without auxiliary support sys- tem are calculated by applying finite element method, respectively. The differences of numerical results under the two situations are studied. The responses distributing influenced by auxiliary support system are analyzed in detail
