摘要： 本文以陶瓷基复合材料天线罩为研究对象,建立了陶瓷基复合材料天线罩和冲破式多瓣分离复合材料易碎盖的有限元模型,采用Abaqus软件进行了陶瓷基复合材料天线罩撞击冲破式多瓣分离复合材料易碎盖过程中的瞬态动力学分析,结合Fortran软件编程,得到了整个撞击过程的动态响应和失效模式,计算结果表明,天线罩撞击易碎盖后,其结构完整性良好,易碎盖从预定的应力槽破坏;进行了天线罩撞击易碎盖的试验,试验结果与有限元仿真结果的一致性良好,为类似型号的设计提供了技术支持。

Abstract: This paper takes the missile radome as the subject of study. The missile radome is made of ceramic matrix composites. The finite element models of both ceramic missile radome and composite petal-type fragile cover are built by FEM. Transient dynamic mechanical analysis for the radome-cover impact process is computed using Abaqus software. In combination with the Fortran programming, the transient responses and the failure modes are obtained after the calculation. Calculation results show that, after the radome-cover impact, the integrity of radome remains unchanged and the protection cover breaks into pieces from the designated stress trough. The impact tests are carried out. The velocity of ceramic missile radome impact on fragile coveris 7.1 m/s. Results from radome to fragile cover impact test show good coincidence with the FEM simulation results. The process and parameters obtained in this paper provide a good guide for similar design.

Key words: ceramic matrix composite, missile radome, transient dynamics, impact process
