Abstract: To deal with problems as incomplete information representation and lack of flexibility in product configuration in traditional product modeling technology, a template-based product information model including functions, principles, structure and knowledge was proposed. In the model creating process, the common features were abstracted from similar functional elements to constitute parametric product template. Functional and structural information of product family were expressed with hierarchical structure and template knowledge was described with object-oriented technology. The template-based product modeling approach was applied in digital product design of small agricultural machinery to reduce the modeling numbers of partial components in a product family and improve the flexibility of product design.

Key words: product template, product model, small agricultural machinery, object-oriented technology, unified modeling language
