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。
In this paper, the finite element model of the solid element of the missile-shell structure of the rocket system and the finite element model of the monolithic shell and beam mixed element were established and the finite element modal analysis was carried out respectively. Compared with the experimental results of the projectile-frame structure, the modeling and analysis The correctness of the method; and provide a reliable basis for the vibration mode test and the dynamic response of the vehicle-mounted rocket launch system. This article uses SDRC’s I-Deas TM software for modeling and analysis.
