| Abstract: |
| Considering the fact that an unreasonable topological form of sructure is sometimes resulted with an improper penalty function of the variable-density-methods,SIMP and RAMP,a new penalty function is proposed in this paper.Based on the new penalty function,the corresponding topology optimum design model is submitted and the iterative design formulae are presented too.Several typical examples are given to demonstrate the method. |
