摘　　要：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。Focusing on the topology model of epicyclic gear trains in the excessive abstraction and the pursuit of extreme divergence,the innovation and optimization design on wheel system failed to achieve the expected results.All kinds of possible configurations of complex topology model are achieved from the topology combination theory based on topological unit.However,due to the complex topologies symbol meaning uncertainty and element meaning still diverge,so between the topology and simulation gear trains still not one to one relationship.To solve this problem,the topology evolution theory is proposed after the combination theory and establishing the evolution rules,the qualitative evolution for the topology elements is realized,the conversion process from combination-topology to assembly-topology is achieved,the purpose of search for all possible topologies are realized.Finally,epicyclic automatic assembly is realized rely on the extract information of assembly-topology which are obtained by computer.The result shows that methods are reasonable and feasible.Through these theories and methods,the foundation of simulation-experiment environment for trains mechanism innovation and optimization design is established,the new ideas for modeling analysis are provided.
