摘　　要：为解决大型工程机械设备的定制设计,满足客户的产品个性化需求,在分析产品定制技术的源流、类型及现状的基础上,针对现有定制方法和技术存在的局限性,提出了一种可视化的工程机械定制模式,建立了可视化定制系统的体系结构.针对工程机械的特点构建了该类产品的分类功能系统,生成与功能模块对应的三维模型.建立了由工程机械外部形态、色彩、装饰方案三部分组成的外观模块及对应的外观模型,和功能模块模型共同构成了完整的产品模型.建立支持各定制模块的A SP数据库,形成了综合产品功能和外观定制的定制系统.在Q uest3D虚拟现实平台上,实现从产品局部定制到整体完成的全过程可视化,保证了定制操作的直观性和定制对象的视觉真实程度.最后,以路面铣刨机可视化定制系统为例,介绍了以铣刨机的功能和外观为主要定制内容的系统工作流程,证明可视化定制模式具有可实现性.To customize large engineering mechanism and meet clients＇ individual demand, on the basis of analyzing the origin, type and current situation of customization technologies, aiming at the limitations of current customization methods and technologies, a visual customization （VC） model for engineering mechanism and the framework of VC systems are established. Based on the characteristics of engineering mechanism, its categorized function system was built, and solid models corresponding to this function module were created. Appearance module made up of exterior shape, color and texture pattern for engineering mechanism was created, as well as corresponding solid models. These models together with function modules constitute the integrated product model. ASP database supporting all customization modules was set up, and then a customization system integrating function customization and appearance customization was formed. On the virtual reality platform of Quest3D, a full visual customization process from parts to integrity was achieved, which assured the visualization of customization and visual reality of cus tomized objects. Finally, By taking VC system for road-surface-cold-milling machine as an exam pie, its main workflow focusing on milling machine＇s function customization and appearance cus tomization was introduced, which practically proved the feasibility of this VC model.
