摘　　要：针对桥式起重机6000余零部件的大装配体三维运动仿真需求,研究了在64位运动分析环境中的实现途径,对运动分析技术做了选型,包括Animator插件、Cosmosmotion插件、方程式驱动、VBA编程、模型建模方法等.通过钢丝绳运动、大装配体的运动关联关系的处理实例具体描述了大装配体运动分析的技术实现方法,编制了VBA运动仿真的计算机代码.运动仿真的动画输出表明,采用VBA技术结合三维造型的参数化方法、变量化方法是有效的大装配体运动仿真实现途径.Aim at the requirements of crane 3D simulation motion in large-scale assembly state, the motion simulation way in 64-bit enviromnent is discussed and the technical methods for motion analysis are selected, including Animator plug-in, Cosmosmotion plug-ins, equation driving, VBA programming, modeling methods. The steel rope movement and association of large assembly handling tbe movelnent are described in detail as an instance of motion analysis method for large assembly, and the VBA code was programmed to assist motion simulation. Animation of motion simulation output shows： Using VBA technology combined with the 3D parameters modeling method and variation method is effective approach to large assembly motion simulation.
