A Variant Design Method of Assembly Based on Tree Structure

Abstract

In the current market demand of rapid response manufacturing, the product variant design technology is one of the key technologies. Product variant design principles and methods are first described. Then, product dimension parameter is analyzed and product dimension parameter transferring structure is studied. Applying tree theory to product variant design, a dimension relation driving-tree of components and parts is constructed and the significance of driving-tree statistics and a dimension parameters transfer method are presented. The methods and processes which are applied to variant design and the sorting algorithm of relations are described in detail. A parameterized variant design module integrated with SolidWorks was developed with VC + +. All the above mentioned methods and processes are verified by taking a joint coupling product as an example.
