摘　　要：针对开展虚拟维修时相关仿真软件缺乏维修工具使用时的可达性分析功能之问题,提出一种可达域计算方法以及可达域的三维可视化方法。首先,根据虚拟人手臂结构特点,计算出虚拟人手臂尺寸;在此基础上,结合工具的外沿点位置,给出工具使用时的最远可达距离计算方法;基于该距离值及虚拟人手臂长度值计算可达域几何体放大尺度,利用该尺度可以对工具使用时的可达域进行三维可视化。最后,结合Jack仿真软件,Tcl/Tk以及Python语言,实现了维修工具使用可达性的分析功能。仿真实例表明:所实现的方法能满足工具使用时的可达性分析,所提供的仿真报告自动生成功能有助于仿真人员编制报告。A method for accessible domains calculation and its three-dimensional visualization is pro?posed in this paper, aiming at the shortage in accessibility analysis functions of the related simulation soft?ware when developing virtual maintenance in the case of using maintenance tools. Firstly, the size of virtualhuman's arm is computed according to its configuration structures. Secondly, a technique to calculate thefarthest accessible distance is given with the information of tools' remote node point. The magnified scale iscalculated by the distance value and the length of the virtual human's arm, and then the scale is utilized torealize visualization for the accessible domain when use the maintenance tools. Finally, the accessibilityanalysis function mentioned above is implemented based on the Jack software with Tcl/Tk and Python pro?gramming languages. The simulation examples show that the proposed approaches satisfy the accessibilityanalysis in the case of using maintenance tools, and the automatic function that generates simulation re?ports will lower the burden of simulation personnel.
