Structural Finite Element Analysis and Optimization of Underwater High Pressure Valve

摘要：

　　The ship side flap valve underwater works with high pressure.In this paper, the valve body is analyzed using seamless connection between the finite element analysis software and Pro/E software.In the analysis, multiple load cases applied to the valve body are as follows: open condition, closed condition and seal test.The analysis result shows the maximum stress value occurs when the flap valve is open.Moreover, stress value is approximately 65 percent the range of the minimum yield strength, but the strength requirement of the valve body is satisfied.Finally, this paper presents a method for weakening the stress concentration effect by increasing the internal transitional fillet radius between the two hollow and intersectant cylinders of the valve body.
