摘　　要：为提高总装装配效率,基于CREO Parametric 3维建模软件,开发一种快速轻量总装装配系统。提取部件模型的表面生成轻量化模型,通过模型参数建立轻量化模型与部件模型顶点、边、面的一一对应关系,使用轻量化模型替换部件模型进行装配,从空间位置的映射和装配约束关系的映射2方面对实体模型的自动映射进行阐述。分析结果表明:该方法能满足快速轻量总装装配的需要,自动将轻量化整机模型下的轻量化模型映射为实体部件模型。In order to improve assembly efficiency,a fast and lightweight assembly system is developed based on CREO Parametric three-dimensional modeling software.The lightweight model is generated by extracting the surface of the component model.The one-to-one correspondence between the lightweight model and the vertices,edges and surfaces of the component model is established by model parameters.The lightweight model is used to replace the component model for assembly.The automatic mapping of the entity model is carried out from two aspects:mapping of space position and mapping of assembly constraints.The analysis results show that the method can meet the needs of rapid and lightweight assembly,and automatically map the lightweight model under the lightweight machine model to the solid component model.
