Firstly,the top-down structure,size chain and spatial relationship were defined;secondly,according to Pro/E single database function and top-down design principle,by extracting the top skeleton controlling parameters,the digital 3D model was set up.
基于Pro/E的自顶向下设计方法对型号为CA3253P7K2T1AE的解放平头柴油自卸重型卡车上装进行结构、尺寸链、空间关系定义,根据Pro/E的单一数据库功能和自顶向下的设计原理,通过提取顶级骨架控制参数,建立数字化三维模型,使顶级骨架控制参数能够驱动数字化三维模型来自动修改工程图和材料BOM,缩短产品设计周期,大大减轻设计人员重复修改图纸的工作量,使设计人员专注于结构优化。
Taking the top-down assemblage of bridge crane as an example,this paper made research on the top-down design process which followed the top basic skeleton model,realized the assembling process successfully,discussed the advantages of top-down design mode and the problems which should take care in the design procedure.

By analyzing product design process,a top basic skeleton(TBS) based model is established spanning from initial-stage conceptual design to final-stage detailed design.
在分析产品设计及其过程的基础上,以顶层基本骨架(top basic skeleton,TBS)模型为纽带,建立起由初期的概念设计到后期的详细设计的产品模型,用以支持产品的整个设计过程;并利用基于评价矩阵的模糊综合评价法评估产品概念设计方案,为产品开发过程的建模提供了有益的探索。
The idea that"Top Basic Skeleton"is bridge of transferring information is established during the design process,and with the 3D parametric design software Pro/ENGINEER.
