由于周转轮系拓扑图的过度抽象及发散性,周转轮系机构的发明创新和优化设计之目的一直未能取得预期成果。以拓扑单元为基础,利用拓扑组合理论有效的获取了各类可能存在的复杂周转轮系的拓扑综合构型,但由于综合构型后拓扑模型元素符号含义仍具有发散及不确定特性,使得拓扑图与三维仿真装配轮系无法形成一对一映射。为此,再建立拓扑组合理论之后又提出拓扑图演化方法,通过建立演化规则实现了组合拓扑图形元素的定性演化,完成组合拓扑到装配拓扑的演化过程,从而真正实现搜索任意可能装配拓扑的目的。最后利用计算机对装配拓扑图形元素进行信息提取,实现装配拓扑与三维仿真轮系的一对一装配关系,结果表明了方法的合理性和可行性,为周转轮系机构的创新和优化设计的仿真实验建立了基础,提供了建模分析新思路。
Due to the excessive abstraction and divergence of the epicyclic topography, the purpose of the inventive and optimized design of the epicyclic gear has been unable to achieve the desired results. Based on the topological element, topology synthesis theory is applied to obtain the topological synthesis configurations of all kinds of complex epicyclic gear trains. However, due to the divergence and uncertainty of symbolic meaning of topological model elements, the topological Figure and 3D simulation assembly wheel train can not form a one-to-one mapping. Therefore, after establishing the topological combinatorial theory, the topological graph evolution method is proposed. The evolutionary rules of the topological graph elements are achieved by establishing the evolutionary rules, and the evolution from the combinatorial topology to the assembly topology is completed. Thus, the purpose of searching for any possible assembly topology is realized . Finally, the information of assembly topological elements is extracted by computer to realize the one-to-one assembly relationship between assembly topology and three-dimensional simulation gear train. The results show that the method is reasonable and feasible, and it can be used to simulate the innovation and optimization design of epicyclic gear train The experiment established the foundation and provided a new idea of modeling and analysis.
