摘　　要：提出以3自由度空间并联机构作为主进给机构,固定平台在水平面上位置可调的一种5自由度并联机床的设计方案。运用Pro/E建立其虚拟运动仿真模型,提出在考虑约束的情况下基于运动仿真进行并联机床工作空间分析的方法,并给出此方法的应用实例。该方法避免了复杂的数学建模与推导,较大程度上减少工作空间分析的工作量。A configuration scheme of a 5-dof adjustable parallel machine tool was presented,by taking a 3-dof spatial parallel mechanism as the main feeding mechanism with adjustable plane position on immovable platform.The virtual kinematics simulation model was established by using Pro/E software,an analytical approach of workspace based on kinematics simulation considering restriction was proposed,and its practical application example was given.The complicated mathematical modeling and deriving are avoided by this method,and the work of workspace analysis is reduced in a larger amount.
