摘要: 钢结构内衬、复合材料外衬火箭定向器在满足强度要求和重复使用的同时,重量得到了极大减轻。但钢-复合材料的复合结构在火箭高温尾流场中呈现出复杂的传热特性。利用ABAQUS有限元分析软件对某钢-复合材料定向器进行传热仿真分析,获得了定向器内的温度分布情况。计算表明,两种材料接合面的最高温度达到268℃,在约4min的冷却过程中复合材料除两端外温度均小于150℃,燃气流对定向器有强烈的热作用。本仿真研究对定向器的结构和热性能设计提供了理论依据,对复合材料和粘合剂的选择有重要的参考价值。

Abstract: The launching tube for rockets which constitute by steel inner lining and composite outer lining has high strength and repeatability but with lower weight. But the coupling structure takes on complex characteristic of thermal under the high temperature rocket jet flow. The simulation of thermal has been done with the ABAQUS software for a steel-composite launch tube, the distribution of temperature for the launch tube has been obtained. The simulation indicates the highest temperature at joint face is 268℃,and the temperature along the tube during 4min refrigeration is basically less than 150℃ except the both sides. The analysis results indicate that the thermal action of jet flow to the launch tube is very strong. The study provides theory warranty for the structure and thermal design of the tube, and has important references to the choice of composite material and bond.
