고압을 받는 MIL-S-46119 원형 밀폐링의 형상 최적화

The optima| design for the shape of MIL-S-46119 ring obturator under the high pressure using parameter study on the stress analysis considering effects or design variable is presented, and it is compared to experimental results. The trends of parametric study arc in good agreement with the experimental results. The more thickness the higher stress. The more taper the higher stress. And maximum stress of circumferential surface is larger than maximum stress of forward surface. The design variables are such as thickness, taper, radius of shape of the obturator. In order to optimize the shape of obturation ring, the weight is maximized subject to maximum stress of the obturator within allowable stress The design constraints are geometric elements of design variables.
