Summary:The invention relates to an aviation blade topological optimization design method based on a selective laser melting process, and belongs to the technical field of mechanical design and manufacturing. The method comprises the following steps: statics analysis of the aviation blade; constructing an aviation blade topological optimization mathematical model based on a variable density method; implementing optimized design of the aviation blade topology by considering the SLM process constraint; reconstructing an aviation blade topology result based on the SLM process constraint; performing strength check on the aviation blade optimization result by adopting a finite element analysis tool; adopting an additive manufacturing process simulation tool to carry out SLM process feasibility analysis on the blade subjected to topological optimization; and guiding the aviation blade model subjected to optimization design into additive manufacturing design to complete manufacturing. According to the topological optimizati
