Based　on　ICM　method,　topological　optimization　model　is　established　to　minimize　the　weight　with　different　constraints.　The　model　is　solved　by　constraint　integrated　method.　The　impact　of　different　filter　functions　on　continuum　structural　topology　optimization　efficiency　is　studied　by　numerical　examples.　The　results　show　that:　The　application　of　nonlinear　filter　function　can　speed　up　the　convergence,　reduce　the　number　of　iterations,　get　a　good　stability　M　the　continuum　structural　topology　optimization.
