Based on the minimum weight principle and service conditions, cylinder shell made by titanium alloy is designed for 2 000 m diving depth using the criterion and finite element analysis.Flat cover with many openings is also designed and ana-lyzed.The design variables are selected and the parameterization FE nodel of pressure shell is established.The optimal structure of pressure shell is attained by using Isight.The pressure experiment is carried out to validate that the proposed design method is suitable and the designed pressured shell can meet the requirements of mechanical performance and weight.
