摘　　要：线缆装配是虚拟装配的重要部分。以悬挂约束状态下待装配的线缆为研究对象,利用悬链线理论推导、建立了二维线缆静态模型。在已知线缆长度和线缆两端点位置的前提下,分析了反求线缆该模型关键参数的快速算法,利用该算法,可以快速确定二维线缆模型,满足线缆装配仿真的实时要求;在此基础上,利用相应的坐标变换算法将二维线缆模型转换为适用于三维虚拟现实平台坐标系的悬挂约束下的3D线缆装配仿真模型。利用建立的线缆装配仿真模型,当线缆端点位置发生移动时,可实时获取各点坐标值,计算、刷新3D线缆装配仿真模型,实现线缆的3D线缆动态建模仿真,同时可以计算出线缆关键点的张力大小,用来指导现实中线缆的装配。It is important for cable assembly to simulate the process planning on mechanical and electrical products in virtual environments. The planar static cable model was proposed according to the theory of catenary for cables to install under the suspended condition. To satisfy the real-time requirement for the cable assembly simulation, the planar cable model could be built rapidly by the algorithm analysis on its key parameters on condition that the cable length and two fixed endpoints of the cable were determined. Using the coordinate transformation method, the 3D cable assembly simulation model under the suspended condition could be gotten from the planar cable model, which is suitable for the environment platform. Using the cable assembly simulation model, the dynamic simulation for cables under the suspended condition could be realized by real-time getting cable＇s terminal point coordinates and computer screen＇s refreshing. At the same time, the tensions of each key point of cables could be computed to guide cable realistic assembly process.
