| Abstract: | The structure of sphere-toroid-cone combined shell with varied curvature is complex and asymmetric,which has an intricate effect on strength,buckling and weight.The structural design based only on the existed rules and experience is not able to meet various requirements.The optimum design is carried out by using the optimization module in ANSYS,in which the smallest mass is taken as the objective function while the strength and buckling as the constraints.In addition,the stress distribution in the sphere-toroid-cone structure is analyzed. |
