1、中文 2955 字 Model evolvement and reuse technology of injection molding machine based on performance knowledge 1 Introduction Performance knowledge occupies an important place in the configuration design of injection molding machines to meet the clients performance requirements. And it is one of highli

2、ghts of product model evolvement and reuse technology. The research of performance knowledge mainly fuscous on product configuration modeling which decides the product functions and quality, performance knowledge expression which helps the product design, product model evolvement and performance kno

3、wledge reuse of injection molding machines. Performance knowledge can drive the product design process. In point of fact, injection molding machines product model itself evolves dynamically and the design knowledge should be reused. As a performance knowledge-based design activity, product model evo

4、lvement and reuse technology has recently attracted a lot of research and industrial interest. Troxlor presented the management of product design knowledge. The knowledge acquirement, model, retrieve and publishment were studied. Pan researched on product innovative design technology based on knowle

5、dge and presented the knowledge model. Tan introduced the multiple ways to express the configuration knowledge in mass customization model. Waterson verified the ontological commitment in knowledge-based system. In modern product design methods, there must be some management and maintenance problems

6、 of product model evolvement and performance knowledge history. Otherwise, the old performance knowledge of completed product should be updated and consummated because of the function improvement, the customer requirement change and so on. That is, the performance knowledge and design result should

7、be improved and modified based on current product model to make it to be a new injection molding machine product which meets the new design requirements. Compared with the original product, the new injection molding machine must have similar structure and coordinate or enhanced functions concurrentl

8、y. Performance knowledge are consummated and enriched during the evolvement process of injection molding machines product model ceaselessly. Now, there are formidable challenges among the manufacturing enterprises in the multi-outlet market economy environment. To make injection machines meet the cu

9、stomers individual requirements, the research on product model evolvement technology becomes more and more important. The dynamic evolvement of injection molding machines product model and the updating and improvement of performance knowledge demand the further research on injection molding machines

Product model dynamics and evolvement driven factors 2.1 Product model dynamics of injection molding machines Every aspect of the process of injection molding machine configuration design determines that it is a dynamic process Its dynami

11、cs mainly appear as the following aspects： (1) Component sets of injection molding machines are dynamic With the evolvement of injection molding machines product model, some new components would be added into the sets， and some old components which were eliminated would be deleted from the sets to p

12、erfect or update the completed products (2) Parts of injection molding machines components are dynamic. Some parts in the product model would remodel their materials, colors and such characters to improve the product model integral performance. (3) Product models of injection molding machine sale dy
