摘要
针对深海极端环境大型生物培养釜的高压大容积,并要求快速开启的特点,提出了一种新型开启结构。首先采用传统的数值设计方法对培养釜进行初步设计,然后结合机械优化设计方法,采用ANSYS软件中提供的一阶优化方法对该培养釜进行应力分析和结构优化设计,得到了合理的结构设计参数。优化结果表明,在培养釜重量减少约7.75%的基础上,应力分布更加均匀合理,优化效果明显。
Considering of the high pressure, large volume and fast-opening characteristics, a new fast-opening structure was adapted for cul- ture vessel in deep-sea extreme environments. Traditional numerical design method was adapted for the preliminary design firstly. Then according to mechanical optimization method, first step optimization in ANSYS software, stress analysis and structural optimization were carried on for culture vessel. The optimization results show that the pressure vessel weight is descended about 7.75% in meeting demand of stress intension, and rational engineering design parameters are obtained for culture vessel new structure.
