Research of Assembly Motion Navigation in Assembly Simulation System

针对在交互式装配过程中零件模型如何精确定位问题,提出了一种基于零件装配特征、体素特征信息的装配运动引导方法,介绍了该方法的设计思想,给出了该方法在装配仿真系统中的实现流程。并对特征信息的获取、装配意图自动捕捉、受约束运动的实现、碰撞检测、装配约束的建立等实现该方法的关键技术进行了较为详细的论述。

It is put forward a method of component motion navigation in the process of assembly simulation. Based on the assembly feature and body element feature, this method can solve the problem about how to locate component precisely in the process of interactive assembly. We described the design idea of this method and the implementation process. We also explained some key technologies for this method in detail, including the information collection for the body element feature, automatic recognition of user intention, constrained motion of the component, collision detection and construction of constraints between assembly parts.
