救生舱的结构的优化设计与试验分析

Optimum design and test research for rescue chamber

救生舱是救生钟或救生艇的主要耐压结构。该结构的设计优化是减少总体重量,增强水下机动性能的主要技术途径。文章针对救生舱进行了结构优化设计,推导了耐压结构的计算公式,通过编制的计算程序对结构进行了优化计算。计算程序可自动优化得到最佳尺寸,也可根据输入尺寸计算结构的耐压能力。在此基础之上,文中设计了工程使用的救生舱结构,对救生舱实物进行了耐压试验考核验证,试验结果证明满足设计要求。

For minimizing the weight of rescue chamber and improving its undersea maneuverability,the typical rescue chamber is designed by using the computer program.The optimum formulae are deduced.The computer program can automatically calculate the optimization dimensions.According to the hydraulic pressure test of actual rescue chamber,the typical stresses are obtained.The test results are very close to the optimum calculation values.
