摘要
通过试验法组合数据并进行数据处理,分别建立了飞机机翼和弹架各个子系统的有限元分析基本模型,然后通过各子系统之间的相互关系和边界条件建立了集总模型。结合集总模型进行动响应分析,从而得到与实际情况较符合的集总模型和有限元分析结果,为弹架系统的动态特性设计提供了一定参考。
Through the test combining with data and data processing,the basic models in finite element analysis of each subsystem including airfoil and missile as well as launcher were established,then the lumped model was set by the correlations and boundary conditions between subsystems.Combined with response analysis of the lumped model,the total model and the results of finite element method,which were about as the same as actual situations,were obtained in order to provide certain references to the design of dynamic behavior for the missile and launcher system.
