【摘要】：作为综合机械化采煤工作面的重要支护设备,液压支架一直具有产品种类多,更新快,需求量大等特点。在以大规模定制生产模式为主导生产模式的今天,中小液压支架生产企业中存在的产品设计方法落后及产品资源管理混乱等问题已经严重制约了企业的发展。因此寻找一种先进的设计方法来提高液压支架产品的设计效率有着重要的意义。本文以液压支架为研究对象,以变型设计理论为基础,对液压支架的变型设计方法及变型设计系统的构建进行了深入研究。在对变型设计理论方法进行深入研究的基础上,将液压支架的变型设计分为零件级、部件级及产品级三个层次进行研究。对于零件级的变型设计,采用系列零件设计表技术来实现零件事物特性表中几何信息的自动存储,并通过编程语言实现产品资源的合理管理。对于部件级的变型设计,利用模块化理论对液压支架产品族进行了模块划分,结合CAD软件的特性,利用自顶向下装配建模方法建立液压支架各模块中不同结构实例的变型主模型,并利用事物特性表实现部件级的变型设计。对于产品级的变型设计,主要研究了变型主模型的建立方法以及变型参数之间关联关系的合理构建方法等。主要研究内容如下:(1)以掩护式支架为例进行模块划分,以底座为例建立各模块及子模块中不同结构实例的自顶向下变型主模型,并建立各实例的事物特性表。对液压支架零件的精确三维模型,建立其系列零件设计表,在此基础上建立零件的事物特性表。(2)利用三维CAD软件SolidWorks建立液压支架的精确三维模型,分析模型约束相关问题,根据模型的简化方法,建立产品级的变型主模型,确定模型变型零部件及其变型参数,建立各变型参数之间的关联关系,利用数值计算方法确定各变型主参数的变型范围。(3)在C#.NET平台上结合Access数据库和SolidWorks软件建立液压支架的变型设计系统,分别设置零件级、部件级和产品级的变型设计模块,并设置了产品实例管理模块,以树形结构管理企业产品资源及各种技术参数等信息,为需求管理模块提供相关的数据基础。本文针对液压支架产品的变型设计方法进行了研究,并构建了较为实用的变型设计系统,大大提高了液压支架产品的设计效率,并实现了产品资源的有效管理,满足了企业的具体要求,有较强的实际意义。
[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.
