摘　　要：构型设计和尺度设计是并联机床设计的关键。该文针对并联机床虚拟样机开发中的构型设计展开研究,给出了并联机床虚拟样机设计流程和系统结构,提出了并联机床虚拟样机概念设计的集成设计方法,该方法集成了4种相辅相成、互为补充的并联机床构型设计方法,举例说明了设计要求输入、运动分配规划、概念设计、运动学分析设计和三维实体建模仿真等关键问题的解决方案。开发了集成化、可视化的并联机床虚拟样机概念设计软件包。Configuration and dimensional designs are the most important techniques in parallelmachinetool (PMT) design. A design flow and a system structure were developed for configuration design in PMT virtual prototyping development. The method integrates four interactional PMT configuration design methods for PMT conceptual design. A design sample was given to illustrate the key techniques in conceptual design for PMT virtual prototyping such as design requirement specification, motion dispatching, conceptual design, kinematic analysis and design, 3D modeling and simulation. A software package was developed for PMT virtual prototyping conceptual design with Unigraphics development tools (UG/Open and UG/Open++) and Visual C++.
