Optimization design of non-pressure tank structure based on simulated-annealing algorithmm
[Objective]Non-pressure tank is an important component of double hull submarine.With the in-creasing diving depth,in order to reduce the structure weight and increase the payloads,the structural form of non-pressure tank of submarine need to be optimized.[Methods]In this paper,the thickness,frame spacing and stiffener section dimensions of the non-pressure tank are selected as the design variables;the structural strength,stability and geometrical requirements are set as the constraints;and the total volume of the structure is determined as the objective function.Based on a simulated-annealing algorithm,a special code and Optimiz-ation Tool are combined to form an optimization plan for a transverse non-pressure tank using Matlab soft-ware with its Optimization Tool,and qualitative analysis is conducted for the optimized design results.[Results]Under the premise of meeting the requirements of recent codes and standards,the results indicate that the structural volume of optimized plan is reduced by 27.2% compared to original plan.[Conclusion]The results of this study can provide useful references for the design of non-pressure tanks.
