摘　　要：以滚子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、尺寸综合问题准确描述和基本思路步骤,构建尺寸坐标系O-r_0re、尺寸域尺寸空间Ω(r_0,r,e)并离散化-网格化处理,提出4项约束条件和解析表达,采取遍历性方法,通过对单一/归并约束的可视映射,得到相应的边界、解域,再据多目标规划、可视映射,发现揭示出"脊点P_(iek)*/脊线lek/脊面Sback"和"脊底点P_(ek)**/壑底点P***"等重要规律、最优解存在性,系统全面解决了对象机构的尺寸综合问题。Taking the disc cams with translating roller follower study object,the organization form,basic /general dimension,accurate description and basic steps for dimension synthesis are given,the coordinate system O- rr_0 e and area dimension space Ω（ r_0,r,e） of dimension are constructed,then discretizeing and gridding of the dimension area is carried out. The four constraint conditions and analytical expressions are put forward,through single or merge visualization- oriented mapping with ergodic method,the corresponding boundary and solution domain are given. Then,according to the multi objective planning and visualization- oriented mapping,it shows some important rules such as carinal dot P_（iek）＊/ crest line lek/ crest plane Sback and the bottom dot P_（ek）＊＊/ valley dot P＊＊＊,it also reveals the existence of optimal solution. All the consequences are instructive to the dimension synthesis of the mechanism.
