| 摘 要: 随着互联网技术的发展，在浏览器网页上展示和操作机械产品装配模型有了非常广泛的应用。针对应用需求，采用新兴的WebGL(Web图形库)，提出了基于浏览器的机械产品虚拟装配展示方法。通过加载服务端STL(立体光刻)三角网格装配模型，对其装配约束关系自动重构，基于WebGL在浏览器上实现装配零部件导航，基于装配约束关系的装配爆炸图自动生成和展示，并以一级减速器为例进行展示系统实验，验证了方法的可行性。 |

| Abstract: With the development of Internet technology, it is widely used to display and operate mechanical product assembly models on web browser. For application needs, this paper proposes a browser-based virtual assembly display method for mechanical products by using emerging WebGL (Web Graphics Library) technology. By loading the server side STL (Stereolithography) triangular mesh assembly model, the assembly constraint relationship is automatically reconstructed. Assembly component navigation is realized on the browser based on WebGL. Assembly explosion diagram based on assembly constraint relationship is automatically generated and displayed. The feasibility of the method is verified by the experiment of display system with the first-stage reducer as an example. |
