摘要

摘要: 定向器是火箭武器系统的重要组成部分，在长期贮存过程中，受到各种应力因素和环境因素的作用，不可避免地发生老化现象，这对武器系统可靠性有着重要影响.该文以玻璃钢定向器为研究对象，进行玻璃钢单向板基本热力学性能试验，并通过试验和测量，获得定向管玻璃钢材料的基本热力学性能，含加速老化后的基本力学性能；构建玻璃钢定向器力学模型，分析其受载时的热力学特性，再建立玻璃钢定向器蠕变模型，即复合材料铺层模型和各向异性模型，在结构模型中进行计算分析，所得的计算参数为建立非金属定向管长贮性能分析的计算模型提供材料参数.

Abstract: The launching tube is an important part of the rocket system. In the process of longterm storage, aging phenomena inevitably occur under various stress and environment factors, with important influences on the system reliability. The glass fibre reinforced plastic (GFRP) launching tube was studied through thermomechanical tests of the oneway GFRP slabs. The tests and measurements gave the basic thermodynamic performances of the oneway GFRP slab materials, including the basic mechanical properties after accelerated aging. The mechanical model for the GFRP launching tube was constructed and the thermodynamic characteristics of the GFRP launching tube under loads were analyzed. Then the creep models for the GFRP launching tubes were established, that is, the composite laminate model and the anisotropic model. With the structural model, the material parameters for the longterm performance analysis of nonmetallic directional tubes were provided.
