复合材料构件发射导弹的动响应分析

DYNAMIC RESPONSE ANALYSIS OF COMPOSITE STRUCTURE DURING LAUNCHING MISSILE

通过对复合材料机翼部件的动特性及动响应分析,介绍了计算分析的方法和步骤;对分析结果的进一步处理及指导改进设计。通过对结构的动特性分析,发现在打样设计局部振动现象,可通过改进铺层设计来消除此设计中的薄弱环节。比较外翼、中翼和内翼3种发射导弹的计算情况,给出最严重情况的动力响应值,最后确定其动强度。

Through the dynamic characteristic and the dynamic response analysis of composites wing, the analysing methods and steps, the further treatment for calculated result and the improvement of design, etc, are presented in this paper. Through the dynamic characteristic analysis of the structure, the lacal vibration is found during the design of layout. The weak parts of the design are eliminated because the lamina design of the corresponding parts are improved. Through the dynamic respose analysis for launching missile, response displacement and response stress are obtained. The three kinds of situation of launching missiles concerned with outboard wing, mid wing and inner wing are compared and the value of dynamic response of the most serious situation is given. In the end, the result of dynamic strength is determined.
