在工程制造中,数控插齿机中床身的拓扑优化问题是比较常见的制造工艺难题,为了解决这个问题,我们探索在有制造工艺约束基础上的拓扑优化模型,在模型中,对中床身进行拓扑优化设计,从中得出了在有工艺约束参数条件下的多种拓扑优化设计结果,这些结果包含了体积分数和制造工艺,是比较合理全面的结果。得到这些结果后,仍需对多种拓扑设计进行分析比较,在总结了实际工作经验的基础上,结合分析结果,基本表明了基于制造工艺约束的拓扑优化设计的数控插齿机中床身拓扑优化设计时最为有效的,最符合生产条件,本文主要就这一设计结果加以研究,以期对工程制造进行有益思考。 In engineering manufacturing, the topological optimization of bed in CNC gear shaper is a common manufacturing process problem. In order to solve this problem, we explore a topology optimization model based on manufacturing process constraints. In the model, Body topology optimization design, derived from a variety of topological optimization design results under the conditions of process constraints parameters, these results include the volume fraction and manufacturing process, is a more reasonable and comprehensive results. After these results are obtained, it is still necessary to analyze and compare a variety of topological designs. Based on the actual work experience and the analysis results, it is basically shown that the bed topology in the CNC gear shaper based on the manufacturing process constraint topology optimization design Optimum design is the most effective, most in line with the production conditions, this paper mainly on the design of this study to study, in order to make useful thinking of engineering.
