针对一种三自由度平动并联机构的结构优化问题进行了研究。设计优化是在具有指定静动力学性能的指定笛卡尔工作空间的基础上进行的。由此产生的机器，螺旋桨，具有三个固定的平行线性关节，垂直安装，和一个移动的平台，在笛卡尔x-y-z空间中移动，具有固定的方向。有趣的特点是一个规则的笛卡尔工作空间形状，在所有方向上的一致性能，以及良好的紧凑性。本文最后介绍了一个正在开发的小型样机。
This paper addresses the architecture optimization of a three-degree-of-freedom translational parallel mechanism designed for machining applications. The design optimization is conducted on the basis of a prescribed Cartesian workspace with prescribed kinetostatic performances. The resulting, machine, the Orthoglide, features three fixed parallel linear joints which are mounted orthogonally, and a mobile platform which moves in the Cartesian x-y-z space with fixed orientation. The interesting features of the Orthoglide are a regular Cartesian workspace shape, uniform performances in all directions, and good compactness. A small-scale prototype of the Orthoglide under development is presented at the end of this paper.
