Optimal Design of Underwater Platform Structure Based on Finite Element Analysis
A composite underwater platform was designed,and its structural points were briefly summarized.A finite element model of the underwater platform was established based on the Patran software,and the strength simulation calculation of the platform was carried out under two working conditions.The influence of wall thickness and winding angle on the platform strength and deflection was discussed.The results showed that when the winding angle was the same,the platform deflection increased with the decrease of the float wall thickness,and when the wall thickness was the same,the platform deflection decreased with the decrease of the winding angle.It was finally determined that the deflection of the underwater platform was 0.151 m and the maximum stress was 60.2 MPa when the pontoon wall thickness was 10 mm and the winding angle was±30°,which met the use requirements,reduced the quality of the underwater platform,and laid a certain foundation for the design and manufacturing of composite materials for the underwater platform.
