| Abstract: | Based on the research of typical numerical example, an engineering constraint method was introduced to overcome the complex of topology optimization results of multiple load cases and dynamic continuum structures. The engineering constraint method was added after the step of the first sensitivities radial filter. The results of several numerical experiments show that engineering constraint technique for multiple load cases and dynamic continuum topology optimization can solve the problem in getting rational and designable results, the material distribution of topology optimization has perfect unanimous feature. |
