| Abstract: |
| To avoid the high computational cost of topology optimization considering the transient dynamic performance, meet the requirements of rapid engineering design and obtain a reasonable structure shape under the main static and dynamic loads, a structural topology optimization method with low computational cost is proposed.The applied dynamic load is an equivalent seismic load, which is determined by the mode decomposition method and the response spectrum curve in the seismic code.The structural dynamic characteristics are optimized by the interaction between structural shape, dynamic characteristics and equivalent seismic static load in the topology optimization.In addition, the automatic evolution strategy of the method is proposed.Numerical examples show that the proposed method can effectively realize topology optimization of structures under static and dynamic loads. |
