摘要： 以平底直动推杆盘形凸轮机构为研究对象,给出机构形态、基本/总体尺寸、尺寸综合问题的准确描述和求解基本思路与步骤,提出3项约束条件及解析表达,构建尺寸坐标系O-r0βe、尺寸空间Ω(r0,β,e),建立面向“科学计算可视化”的数学求解模型,采取遍历性方法,先得到单一约束的可视边界、解域,继而据多目标规划归并约束,得到归并约束边界面/解空间,分析论证得到“最优解/解区间/解集”、“非劣解区间/解域”和“谷底点”等重要规律,以及尺寸最优解存在性特征,以一种行之有效的通用求解方法解决了对象机构的尺寸综合问题,为对象机构基本尺寸的选择与工程设计奠定了理论基础.

Abstract: According to the study in disc cams with translating flat-faced follower, the paper showed the organization's form, basic dimension, accurate description and basic steps for dimension synthesis. It also offered three constraint conditions and parsing expressions, then built the dimension area and constructing coordinate system O-r0βe and area Ω(r0,β,e) of dimension, as well as establishing mathematical model based on “Visualization in Scientific Computing”. Through single or merge visualization-oriented mapping with ergodic method,some comparable boundaries and solution domains were given. According to the multi-objective planning, several important rules such as “the optimal solution/solution interval/solution rendezvous” and the “non-inferior solution interval/solution domain” were presented. This paper also revealed the existence of optimal solution. All the consequences were instructive to the dimension synthesis of the mechanism with an effective general solution method, as well as establishing the theoretical foundation for the selection of basic size and engineering design of the mechanism.
