机电产品的全三维设计要求对全部线缆组件进行几何建模,然而CAD环境下基于交互的线缆组件的三维几何建模过程十分耗时,影响产品设计周期。为了提高线缆组件的几何建模效率,研究了基于Pro/Toolkit的线缆组件快速几何建模技术。首先给出了线缆组件快速几何建模的流程,建立了线缆组件的信息模型。分析了Creo环境下线缆组件的几何建模需求,提出了基于Pro/Toolkit的线缆组件自动几何建模方法。最后通过某机电产品的布线三维模型,快速建立了线缆组件几何模型,验证了所提方法的有效性。

It the 3 D design of mechanical and electrical products,all cable harness components are required to build the geometric models. However,the process of 3 D geometry modeling of the cable harness based on interaction in CAD environment spends much time,thus affecting the product design cycle. To improve the efficiency of the cable harness geometric modeling,a rapid geometry modeling technology based on Pro/Toolkit is studied in the paper. Firstly,the process of its rapid geometry modeling is presented and the model of cable assembly＇s information is established. Based on the analysis of the geometric modeling requirement of the cable assembly in Creo environment,the automatic geometry modeling method based on Pro/Toolkit is put forward. Finally,a cable assembly geometric model is established on a 3 D model of a certain mechanical and electrical product,which is used to verify the validity of the proposed method.
