轻质耐压壳体减重研究

本文结合几种材料的特性，对壳体的结构做了力学分析，研究了轻质耐压壳体的减重方向。研究中发现，隔板的设计对壳体的重量影响很大，因此详细分析了凹凸两种形式端板的力学特性，发现同等厚度条件下，凸型隔板的变形量小、安全系数高。分析对比了铝基合金、复合材料、钛合金的材料特性、加工特性、国内开发现状以及成本，认为现阶段应以铝基合金的改进为主，并关注其他材料的进展对壳体进行减重设计。

Study on Weight-reduction of Compressive Shell

This paper discusses how to reduce the weight of the shell(Weight-reduction).It analyses the structure of the shell in connection with some materials.The structure of the clapboard is the key to weight-reduction,which is studied in details in concavo-convex shapes.In the same thickness,the convex shape has smaller distortion and higher safety factor.Al-based alloy,multiple materials,and Ti-based alloy are compared in mechanics,cost and the domestic recent development.According to the factors discussed above...
