- Abstract
To prevent the numerical instabilities about checkerboards, mesh-dependency and localized eigenmodes in structural topology optimization with frequency constraints , an improved ICM method based on the new sine-type filter-polish function is presented. Moreover, sensitivity filter of difference of the strain energy and the kinetic energy of ith element corresponding to the jth eigenmode is adopted in dynamic optimization process. The sequential quadratic approximate algorithm is applied to solve the optimal model for continuum structure established in this paper.
