| Abstract: | Using the sensitivity analysis function of MSC Nastran, the materials young modulus is taken as the design variable parameters, and a method is proposed to identify the weaker joints. By referring to the sensitivity analysis result, the structure of some parts is optimized to improve the structure performance of BIW, improve structure performance and verify the effectiveness of the method. |
