摘　　要：提出一种以Agent技术为基础的多层分布式的虚拟场景模型。先从装配体的视角构建装配信息模型,根据刻画特征对象的各项参数定义装配知识层;装配决策层将零件视为Agent,并定义Agent间传输状态参数的消息模板,同时根据虚拟装配任务的过程特点,建立决策规则;最后,定义用户控制层的运动控制算法,实现对用户的运动引导。实验表明该场景模型可在虚拟场景中有效呈现装配任务,并根据上下文情境准确理解用户意图。An agent-based distributed multi-layer virtual assembly model is proposed. Firstly,we construct an assembly information model in the sight of each component,define the assembly knowledge layer based on a series of parameters used to describe feature object. The assembly decision layer treats the parts as individual agents,and defines a series of message templates for transforming parameters between agents. To help agents make proper decision,decision rules are summarized based on process of virtual assembly. Finally,the control layer is defined with a dynamic DOF updating algorithm,to lead users＇ operation in a proper order. Experiment result shows that the proposed model can understand user behavior nicely.
