| Abstract: | Based on the plane continuum,the mathematic model of topology optimization was established,and a new topology optimization method of continuum structure was proposed.The k-nearest neighbor algorithm is used to conduct the operation of structure topology optimization in this method.The computation formula is provided,the deleting rate and evolving rate are defined.Several numerical examples are given and the optimal results are close to which obtained by the other method.The comparison indicates that the topology optimization method of continuum structure based on k-nearest neighbor is feasible. |
