基于聚四氟乙烯的水下航行器壳体优化设计

摘要

本文根据某型特种ROV的浮力冗余要求,以ROV最大内部容积为目标函数,相关设计参数为设计变量,建立壳体优化设计模型.利用全局搜索求解器globalsearch和局部寻优求解器fmincon进行求解,优化后的壳体内部容积提高9.46%,相应质量减少为42.38%,满足设计要求.%According to the buoyancy redundancy requirements of a special ROV, the optimal design model of the shell is established by taking the maximum internal volume of ROV as the objective function and the relevant design parameters as the design variables. The global search solver globalsearch and the local optimization solver fmincon are used to solve the problem. The optimized internal volume of the shell is improved by 9.46%, and the corresponding mass is reduced by 42.38%, which meets the design requirements.
