摘　　要：针对系列化产品设计中信息共享程度低、信息传递速度慢、重复劳动多的问题,提出了一种面向网络化的参数化协同设计方法。分析了分布式协同设计中共享冲突和网络异构的问题,提出了基于PDMWorks Workgroup协同设计平台的构建方法。研究了角色权限分配和数据并发控制的机理,制定了面向网络化的协同设计通讯机制。结合桥式起重机的结构特点,将参数化变型设计和协同设计有机地结合起来,开发了面向网络化的桥式起重机参数化协同设计系统,并以主梁设计为例进行了验证。Aiming at the problems of low level of information sharing,slow transmission of information,repetitive work in the design process of serial mechanical products,we present a new method of parametric collaborative design which is network-oriented.We analyze the information sharing conflicts and network heterogeneity in the distributed collaborative design and propose a method for building a collaborative design platform based on PDMWorks Workgroup.By studying the mechanisms of role distribution and concurrent control of data,we formulate the communication mechanism of the network-oriented collaborative design.Considering the structural characteristics of an overhead traveling crane,we combine the parametric variant design with the collaborative design,develop the overhead traveling crane′s parametric collaborative design system which is network-oriented and verify our new method with the design of a main girder.
