Abstract: Disclosed is design optimization method of the structure considering centrifugal loads and stress constraints. Compared with the prior art, this application improves the method for obtaining the relaxation coefficient c, including the calculation of the second predicted maximum stress based on the predicted stress method from steps S9.1 to S9.8. The influence of the existence of jagged boundaries and gray densities on the calculation of the structural stress field is reduced. The most important thing is to decide whether to use linear penalty or nonlinear penalty for the elastic modulus of each element according to the ratio of the number of elements with design variables less than 0.1 and greater than 0.9 to the total number of elements. Introducing the predicted maximum stress can make full use of the allowable stress of materials, improve the quality of optimization design, and obtain a design scheme with a lighter mass.
