研究面向设计意图的语义在线交换与共享对智能制造环境下协同产品智能设计知识重用和知识创新具有非常现实的意义。项目从当前研究存在的设计意图描述完整性和标准化的现实问题出发，研究融合设计目的意图和设计思考意图为一体的语义云粒元模型，建立符合云计算粒子和语义网语义元二者特性的语义云粒元，在此基础上研究针对STEP AP242应用协议标准的STEP语义云粒元的构建方法；结合深度学习和语义可视分析方法，研究构建支持设计思考意图的语义云粒元知识链网络，实现语义云粒元的动态关联、自导航和重定位等语义云粒元重组过程，从而实现设计意图的语义在线交换与共享。

It is important to research design intent-oriented semantic exchange and sharing for collaborative product design knowledge reuse and knowledge innovation in the smart manufacturing. According to the current drawback on the integrity of design intent description and standardization,on the basis of the STEP AP242,the semantic cloud particles model which combined the design goal intention with design thinking intention is put foward. And then the semantic cloud particles with the ability of self-organizing fractal features and navigation links is builded.With the Visual Analytics and Deep Learning techniques, build the semantic cloud particles-based knowledge chain network and design Granular Computering-based semantic cloud particles reorganization so as to achieve dynamic association, self-navigation and relocation in order to realize the dynamic semantic exchange and sharing of design intent
