产品装配工艺虚拟规划系统研究

A Product Assembly Virtual Planning System

装配是决定产品制造质量的最终环节,是复杂产品结构设计和工艺规划的关键内容。基于虚拟现实的产品装配智能规划技术,被认为是支撑智能制造的关键使能技术之一。首先在虚拟现实环境中,研究了基于材质、表面纹理、三维模型等多信息融合的多视图模型表示方法。然后以减速器为对象,应用Virtools引擎,基于装配约束驱动开发了一套产品装配智能规划原型系统,基本实现了装配序列规划、装配路径规划、人机工程模拟、装配干涉检验、装配优化报告生成等过程的自动化和智能化。重点解决了虚拟装配智能引导、装配路径自动规划、多视图模型表示等关键技术难点。

Assembling is the final step that determines the quality of the products, and is the main contents of the product design and process planning. The intelligent assembling process planning based on the virtual reality is regarded as an enabling technology to support the intelligent manufacturing. Firstly, the presentation method of multi-view modeling was studied using the information of material, sut.face texture as well as 3D ＆ 2D mode/s. Secondly, a prototype system of product assembling system was developed via Virtools with the reducer as an example. And the system can achieve the following function automatically： assembly sequence planning, assembly path planning, assembly ergonomics simulation, interference analysis and so on.
