Research On Variant Design System Of The Wall Jib Crane Based On Product Gene

In the world scope, with the shaping of purchaser market, the customer personalized requirements on the crane become more and more. At the same time, owing to some design problems, it seemed to be an inability to respond quickly enough to the marketplace for the crane industry. The object of the paper is the wall jib crane. It has larger work space and flexibility, but it has small-tonnage, as a result, it can be used in the factories, the warehouse and some other places.Firstly, this paper explained why selecting the title and the significance of the research. Secondly, the present situation and the development of the domestic and foreign crane industry were introduced. Then, the research statuses of product gene and variety design were analyzed in the paper. Finally, the paper put forward variant design based on product genetic for the problems in traditional variant design methodology, and applied it to the wall jib crane variant design.In the aspect of theory, compared with the biological growth process, this paper studied the concept of gene. The features and the content of the product gene were also introduced. And the product gene model was described. The genetic model in the gene variant design process was also analyzed. Then the support product design theory was proposed, including the theory of decomposition and reconstitution, growth theory and function surface theory.In technology applications, on the one hand, the key technologies of variant design based on product gene were introduced, such as product gene extraction, product gene amplification, product gene recombination and product gene expression. On the other hand, the technological structure of the variant design platform based on product gene was studied. The features and development method of the variant design platform were introduced. Product family gene modeling technology and implementation technology were also introduced, at the same time, the product gene encoding technology such as interface encoding was researched. Finally, the management and establishment of product gene databases were studied. As the application of the above theory and technology, the system used VB.NET2005to develop INVENTOR2011. Developing the variant design system of the wall jib crane based on product gene, its database is Access2007. The whole system included customizing module and variant design module. The variant design of wall jib crane was preliminary implemented, and the result had shown that the system was reliableThe variant design system of the wall jib crane is based on product gene. It achieves automation of products design in certain degree. The system improves the design efficiency, satisfies the varying market needs, shortens the design cycle greatly and decreases the cost for the corporation.
