Abstract

Topology optimization under dynamic constraints is challenging problem requiring special optimization procedures involving solution at each iteration step an eigenvalue problem. In this study we propose simple yet effective procedure of topology optimization under various dynamic loadings. The effectiveness of the proposed methodology is related with quasi-static approximation of the optimization process. Effectiveness of the proposed approach has been demonstrated on a topology optimization of a beam supporting ramp structure. Based on a number of modes it was concluded that proposed method can increase selected natural frequency by a factor of 3.
