| Traditional chemical industry pressure vessel was designed with large wall thickness, which increases the production cost. The elliptical head pressure
vessel and the dished head pressure vessel were two different kinds of convex head pressure vessel, whose characteristics of stress and displacement distribution were investigated and
optimized by ANSYS finite element analysis software. The results show that under the same load, the stress of the elliptical head pressure vessel is smaller than that of the dished head
pressure vessel; the change trend of the semi minor axis of the elliptical head pressure vessel and the straight section inner diameter of the dished head pressure vessel is consistent with the
maximum volume of objective function. The optimal design parameters of the pressure vessel were obtained after 21 iterations with obvious optimization effect. The results have a certain
guiding significance for the optimal design of pressure vessels and the rational use of materials. |
