Classical mechanism theory focused first on the analysis and synthesis of planar (2-D) mechanisms, and more recently on the analysis and synthesis of spatial (3-D) mechanisms. This research project seeks to extend 3-D analysis and synthesis methods to higher-order joints (which may be viewed as combinations of simple joints), and to embed the methods in CAD systems useable by mechanical designers without advanced training in mechanism synthesis. The research is focused on obtaining exact closed-form analytical solutions for the equations of motion (rather than computed approximate solutions), and on dimensional rather than form synthesis. (Dimensional synthesis seeks viable positions and lengths for a prescribed collection of joints and links; form synthesis treats alternative collections of joints and links).

经典的机构学理论首先侧重于分析和综合 平面（2-D）机构，最近的分析和 空间（3-D）机构的综合。 该研究项目旨在 将三维分析和综合方法扩展到高阶节理（ 可以被看作是简单关节的组合），并嵌入 在CAD系统中使用的方法，机械设计师没有先进的 机构综合培训。 研究的重点是获得 运动方程的精确封闭解析解 （而不是计算的近似解），而在尺寸上， 而不是形式合成。 （维度合成寻求可行的位置， 规定的接头和连杆集合的长度;形状合成 处理关节和链接的替代集合）。
