| Abstract: |
| In this paper the improved ESO method based on SIMP is presented, which is a combination of ESO and SIMP. The step length of evolution is reduced so that the accuracy of sensitivity analysis can be improved. The SIMP method is employed to describe the relationship between the relative density and the stiffness of grey elements. With logical parameter the numbers of grey elements can be controlled, so the topology can be clear and easy to manufacture. Topology optimization of continuum structures considering self-weight is carried out by this method, and more optimal results are obtained than those by traditional ESO method. |
