摘要：

A　new　exist-null　combined　model　is　proposed　for　the　structural　topology　optimization.　The　model　is　applied　to　the　topology　optimization　of　the　truss　with　stress　constraints.　Satisfactory　computational　result　can　be　obtained　with　more　rapid　and　more　stable　convergence　as　compared　with　the　cross-sectional　optimization.　This　work　also　shows　that　the　presence　of　independent　and　continuous　topological　variable　motivates　the　research　of　structural　topology　optimization.
