[Abstract]:As an important supporting equipment of comprehensive mechanized coal mining face, hydraulic support has been characterized by many kinds of products, rapid renewal and large demand. With mass customization as the leading mode of production, the development of medium and small hydraulic support enterprises has been seriously restricted by the backward product design methods and the confusion of product resource management. Therefore, it is of great significance to find an advanced design method to improve the design efficiency of hydraulic support products. Based on the theory of variant design, the variant design method of hydraulic support and the construction of variant design system are studied in this paper. On the basis of deeply studying the theory and method of variant design, the variant design of hydraulic support is divided into three levels: part level, component level and product level. For the variant design of part level, the technology of series part design table is adopted to realize the automatic storage of geometric information in the table of parts' characteristics, and the reasonable management of product resources is realized by programming language. For the variant design of component level, modular theory is used to divide the product family of hydraulic support, combined with the characteristics of CAD software, Based on the top-down assembly modeling method, the variant main model of different structure examples in each module of hydraulic support is established, and the variant design of component level is realized by using the tabular table of things characteristics. For the variant design of product level, the establishment method of the variant master model and the reasonable construction method of the relationship between the variant parameters are studied. The main research contents are as follows: (1) take the sheltered bracket as an example to divide the modules, take the base as an example to establish the top-down main model of different structural examples of each module and sub-module, and establish the list of things characteristic of each instance. For the precise 3D model of hydraulic support part, the design table of its series parts is established, and on the basis of this, the object characteristic table of the part is established. (2) the accurate 3D model of hydraulic support is established by using 3D CAD software SolidWorks, and the problems related to model constraint are analyzed. According to the simplified method of the model, the variant main model of product level is established, and the variant parts and their variant parameters of the model are determined, and the relationship between each variant parameter is established. The variation range of the main parameters is determined by numerical calculation method. (3) the variant design system of hydraulic support is established on the platform of Access database and SolidWorks, and the variant design modules of parts level, component level and product level are set up, respectively. A product case management module is set up to manage the information of enterprise product resources and various technical parameters with the tree structure to provide the relevant data basis for the demand management module. In this paper, the variant design method of hydraulic support products is studied, and a more practical variant design system is constructed, which greatly improves the design efficiency of hydraulic support products and realizes the effective management of product resources. Meet the specific requirements of the enterprise, has a strong practical significance.
