摘要
本文建立了火箭发系统的弹 -架结构实体单元有限元模型及整体结构壳梁混合单元有限元模型并分别进行了有限元模态分析 ;对比弹 -架结构试验结果 ,验证了建模及分析方法的正确性 ;并为车载火箭发射系统整体结构振动模态试验及动态响应提供了可靠的依据。本文采用SDRC公司的 I-Deas TM软件进行建模及分析。
Finite element models of rocket support and the whole rocket launcher system are built in this paper,and finite element modal analyses are finished.The modeling and analyzing methods are verifed by comparing with the results of experiments of rocket support.Also a reliable reference to mode experiments and dynamic responses of the whole rocket launch system is provided.
