Parametric Collaborative Design of Network-based Mechanical Products

摘要

Aiming at the problems of low-level information sharing,slow transmission and repetitive work in the designing process of product series,the internet-oriented parametric collaborative design method is proposed,in which the problems of sharing conflict and network heterogeneous in the distributed collaborative design are analyzed,and the construction method of collaborative design platforms based on PDMWorks Workgroup is put forward. Through studying the mechanism of roles distribution and function allocation and data concurrency control,the communication mechanism of internet-oriented collaborative design is formulated. On the basis of structure features of overhead travelling crane,through combining parametric variant design with collaborative design,internet-oriented parametric collaborative design system of overhead travelling crane is developed and verified through main girder design.
