| 摘 要： | 以滚子中心C(u,v)为牵引变量，系统分析讨论了整程区域套Γ*(x,y)/边界Γ*(x,y)的性态多样性。通过引入简约遍历区域Σ[2]和Σ[0]的概念和离散-网格化处理方法，提出了并解区域Ω*[2/0](u,v)/Γ*[2/0](x,y)的概念和求解方法。构造坐标系Ouvr**0min，生成了三维曲面S**，提取了性态特征--谷脊线J**和谷底点P**，揭示出最紧凑机构尺寸解的存在性并给出求解方法，解决了做平面运动滚子从动件盘形凸轮机构的泛类尺寸综合问题。

| Abstract: | The roller center C(u,v) was selected as a variable, and the possibilities of instantaneous area set Γ*(x,y)/boundary Γ*(x,y) were systematically analyzed and discussed. By introducing the concepts of simple ergodic region Σ[2] and Σ[0], and the approach of discrete-grid, the concepts and solutions of union of solution area Ω*[2/0](u,v)/Γ*[2/0](x,y) were proposed innovatively. Coordinate system Ouvr**0min was constructed, three-dimensional surface S** was generated, and the characteristics of state-edge of regression J**and bottom point P** were extracted to reveal the existence of the most compact mechanism size solution and the solution method, which solved the general class size synthesis tasks of disc cam mechanisms with roller follower moving in planar general motions. |
