复杂变型产品参数传递结构研究

针对基于3维模型的复杂产品变型，提出了与产品建模结构相融合的树形参数传递结构。该结构规定参数只允许纵向传递，避免了参数之间的交叉传递，为复杂产品变型设计提供了有效的变型信息传递通道，并在此基础上实现了参数传递结构的模块化。以Solid Edge 3维造型软件为设计环境，以VB为工具开发了剑杆织机变型设计系统，阐述了剑杆织机建模、参数传递和产品变型设计的关键技术及其实现方法。

Parameters transfer structure for complicated product variant design

To deal with 3-dimension variant design for complicated product, an optimal tree-structure for the parameters transfer was proposed for complicated product variant design. In the tree-structure for the parameters-based remodeling, only vertical transfers were permitted and cross transfers were forbidden. So the tree-structure set an agile and credible parameter transfer channel for variant design, and provided the foundation for the modularization of the parameter transfer structure. Finally, taking Solid Edge as a 3D environment and VB as a development tool, a variant design system was developed for the variant design of complicated rapier loom, the loom modeling techniques and variant parameters transferring were expatiated.
