摘　　要：随着世界军事科学的日益发展,纤维增强复合材料在武器装备上得到越来越多的应用,为了深入研究纤维增强复合材料定向器的刚强度,必然要对各种参数进行大量的实验,造成效费比很高。为解决这个问题,文中用数值仿真的方法对玻璃纤维增强复合材料火箭定向器进行了研究,计算了火箭在定向器内运行的全过程,得到了复合材料定向器的一些有价值的计算数据曲线。数值计算结果与实际数据对比,取得良好的一致性。研究表明,用该复合材料制成的火箭定向器完全能够满足工程需要。With the development of world military science, fiber reinforced composite materials are applied to weapon more and more. For researching fiber reinforced composite material rocket launch tube, many experiments have to be done. This will spend a large amount of manpower, resources and money. So in order to solving this problem, the paper researched the fiber reinforced composite material rocket launch tube by numerical simulation. Transient dynamic analyses of the models were computed. The process of the rocket moving in the tube was described. Some valuable data curves of composite material rocket launch tube were obtained. The computed results were in good agreement with those of the practical data. The research work also shows that the rocket launch tube made by this composite material is feasible.
