Optimization Design of Corrugated Bulkhead of Bulk Carrier Based on HCSR Prescriptive Requirements
The corrugation parameters for corrugated bulkheads are usually determined based on the parent ship or the expe-rience of engineers.The optimization design method and flow of the corrugated bulkhead were proposed by using the Excel-Hyper-Study integrated optimization model.Based on the HCSR prescriptive requirements,the requirements of the local strength,corru-gation bending resistance,web shear resistance and web shear buckling of corrugated bulkheads were summarized.The key tech-nologies for the optimal design of the corrugated bulkhead were put forward,such as the arrangement of the corrugated bulkheads,the load calculation point,the arrangement of the seams of the corrugated bulkhead,the average length of the corrugated bulk-head and the mass of the corrugated bulkhead.The optimal mathematical model to minimize the mass of the corrugated bulkhead was given.The acceleration,loads and strength requirements of corrugated bulkhead under each loading condition were setup,and the Excel-HyperStudy integrated optimization process was established by taking the corrugated bulkhead of a non-gale ballast tank of a bulk carrier as an example.Compared with the traditional method,the correlation between the design object and each parameter can be obtained more accurately and the design scheme with better weight can be obtained by the proposed optimization method.
