Study On Key Technologies Of Variant Design For Hydraulic Support Based On Product Family

In this dissertation, product family, modular technology, tabular layouts of article characteristics (SML) technology, methods and key technologies of product variant design are studied systematically; the parametric variant design system for hydraulic support based on product family is designed and developed according to characteristic of hydraulic support. The system can make out hydraulic support products that satisfy customers quickly by making full use of present enterprises resource, while it can shorten the design period of hydraulic support and enhances enterprise's market competition ability. The main research contents are as follows:1. The parametric variant design system's function model and systematic structure are put forward by investigation and analysis on present situation of hydraulic support product design in enterprises, and it's development tools and supporting environment are established, including technique, function and data layer.2. The modular design is introduced to product family model. Then module dividing principle of hydraulic support is proposed and its division is given. After characteristics of product series in product family are provided, the mapping relationship between function model and mechanical structure of hydraulic support is built.3. The key technologies and methods of hydraulic support parts variant design and product configuration using SML are introduced after parameters selection and construction steps of SML are introduced. Then key configuration parameters of hydraulic support are analysed based on rough set theory.4. The ways of automatic assembly for hydraulic support and correlation functions are studied based on technical basis of second development of Pro/ENGINEER and automatic assembly. More over, the constraint function like"pin"in hydraulic support is defined and product automatic assembly is realized.5. The hydraulic support parametric variant paramatic design system is developed by second development of Pro/ENGINEER by using of Pro/TOOLKIT based on SQL Server database system and software platform as Visual C++ 6.0, which realizes some functions, such as variant design, attribute management and product configuration of hydraulic support.
