【摘要】：作為綜合機械化采煤工作面的重要支護設備,液壓支架一直具有產品種類多,更新快,需求量大等特點。在以大規(guī)模定制生產模式為主導生產模式的今天,中小液壓支架生產企業(yè)中存在的產品設計方法落后及產品資源管理混亂等問題已經(jīng)嚴重制約了企業(yè)的發(fā)展。因此尋找一種先進的設計方法來提高液壓支架產品的設計效率有著重要的意義。本文以液壓支架為研究對象,以變型設計理論為基礎,對液壓支架的變型設計方法及變型設計系統(tǒng)的構建進行了深入研究。在對變型設計理論方法進行深入研究的基礎上,將液壓支架的變型設計分為零件級、部件級及產品級三個層次進行研究。對于零件級的變型設計,采用系列零件設計表技術來實現(xiàn)零件事物特性表中幾何信息的自動存儲,并通過編程語言實現(xiàn)產品資源的合理管理。對于部件級的變型設計,利用模塊化理論對液壓支架產品族進行了模塊劃分,結合CAD軟件的特性,利用自頂向下裝配建模方法建立液壓支架各模塊中不同結構實例的變型主模型,并利用事物特性表實現(xiàn)部件級的變型設計。對于產品級的變型設計,主要研究了變型主模型的建立方法以及變型參數(shù)之間關聯(lián)關系的合理構建方法等。主要研究內容如下:(1)以掩護式支架為例進行模塊劃分,以底座為例建立各模塊及子模塊中不同結構實例的自頂向下變型主模型,并建立各實例的事物特性表。對液壓支架零件的精確三維模型,建立其系列零件設計表,在此基礎上建立零件的事物特性表。(2)利用三維CAD軟件SolidWorks建立液壓支架的精確三維模型,分析模型約束相關問題,根據(jù)模型的簡化方法,建立產品級的變型主模型,確定模型變型零部件及其變型參數(shù),建立各變型參數(shù)之間的關聯(lián)關系,利用數(shù)值計算方法確定各變型主參數(shù)的變型范圍。(3)在C#.NET平臺上結合Access數(shù)據(jù)庫和SolidWorks軟件建立液壓支架的變型設計系統(tǒng),分別設置零件級、部件級和產品級的變型設計模塊,并設置了產品實例管理模塊,以樹形結構管理企業(yè)產品資源及各種技術參數(shù)等信息,為需求管理模塊提供相關的數(shù)據(jù)基礎。本文針對液壓支架產品的變型設計方法進行了研究,并構建了較為實用的變型設計系統(tǒng),大大提高了液壓支架產品的設計效率,并實現(xiàn)了產品資源的有效管理,滿足了企業(yè)的具體要求,有較強的實際意義。
[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.
