某型导弹贮存架模态分析

Modal Analysis of a Certain Missile Storage Shelf

基于ANSYS软件平台，在模态分析理论基础上，对某型舰载导弹贮存架结构进行了模态分析，得到了贮存架结构前十阶模态结果；着重分析了前五阶模态振型，指出了贮存架弯曲振动和扭转振动是其结构动态特性的主要表现形式；指出针对导弹贮存架结构进行的模态分析，可为贮存架结构的动力学研究工作提供基础和依据。

Based on the platform of ANSYS, the modal of a certain ship-borne missile storage shelf structure was analyzed in the modal analysis rationale. The result contains first ten modals. The first five vibration modals were analyzed emphatically. It＇s pointed out that the flexure vibration and the torsion vibration were its structure dynamic characteristic main manifestations. The modal analysis that carries on view of the missile storage shelf structure may provide the foundation and the basis for the next storage shelf structure dynamics research work.
