【摘要】：随着这几年的矿车行业的深入发展,客户的个性化需求越来越明显,企业之间的竞争焦点开始转向以客户为驱动的需求定制、客户满意度的提升、企业服务质量的提高,这给传统矿车企业的产品设计方法带来了巨大挑战。因此,研究一种针对矿车产品能够进行系列化设计的方法显得尤其重要,具体研究内容如下：(1)针对现有的系列化设计方法不能满足矿车系列化设计,在分析相似理论和模型设计的基础上,深入研究了系列化设计的方法,比较了模型设计与系列化方法的相似之处,将模型设计和产品系列化方法相结合,提出了基于模型设计的相似系列化设计方法,为后续的系列化设计奠定理论基础。(2)研究了底侧卸式矿车的结构原理,在功能分析的基础上,从产品层次到零件层次进行模块划分并进行隶属编码；针对产品系列化的应用需求,对产品装配模型和建模方法进行了研究,分析了SolidWorks草图绘制、特征操作,归纳出零件的参数化特征建模的规则以及产品装配的方法和关系。(3)利用车箱层次化建模,得到车箱的无量纲数表达式,采用相似理论与量纲分析法,对车箱的规格进行了系列化设计,得到了车箱的规格系列,为产品系列化设计提供了数值条件。(4)针对产品变型参数相互约束形成的网状结构,研究了的事物特性表的数据存储结构和零件优先级设计规则,以此来确定参数传递顺序,为产品变型建立准确可靠的参数传递通道,通过对参数进行映射传递完成产品实例的重置并对工程图进行调整。(5)研究了车箱在满载时的力学特性,通过ANSYS Workbench进行FEA分析,得到满载状态下车箱的总变形和等效应力情况,验证了系列化方法的可靠性。(6)针对产品系列化需求对系统的整体构架进行设计,以SolidWorks为CAD平台,运用VC++开发工具,结合Access数据库开发出底侧卸式矿车产品系列化设计系统。
[Abstract]:With the further development of mining car industry in recent years, the individuation demand of customers is becoming more and more obvious. The focus of competition among enterprises has begun to shift to customer-driven demand customization, the improvement of customer satisfaction, and the improvement of service quality. This brings a great challenge to the product design methods of traditional mining vehicle enterprises. Therefore, it is particularly important to study a method that can carry out serialized design for mining vehicle products. The specific research contents are as follows: (1) in view of the fact that the existing serialization design methods can not meet the needs of the series design of mining cars, on the basis of analyzing the similarity theory and model design, the serialization design method is deeply studied. The similarity between model design and serialization method is compared, and a similar serialization design method based on model design is proposed by combining model design with product serialization method. In this paper, the structure principle of the bottom side unloading mining car is studied. On the basis of function analysis, modules are divided from product level to part level and membership coding is carried out. According to the application requirements of product serialization, the product assembly model and modeling method are studied, and the SolidWorks sketch drawing and feature operation are analyzed. The rules of parameterized feature modeling of parts and the method and relation of product assembly are summarized. (3) the dimensionless expression of car-box is obtained by using hierarchical modeling of car-box, and the similarity theory and dimensionality analysis method are used. The specifications of the carts are serialized, and the series of specifications of the carcases are obtained, which provides numerical conditions for the serialization design of the products. The data storage structure and part priority design rules of the object characteristic table are studied in order to determine the parameter transfer order and to establish an accurate and reliable parameter transfer channel for the product variant. In this paper, the mechanical properties of the carbox at full load are studied by mapping the parameters to complete the reset of the product instance and adjusting the engineering drawing. The total deformation and equivalent stress of the carbox under the full load state are obtained by FEA analysis by ANSYS Workbench, and the total deformation and equivalent stress of the carbox under the condition of full load are obtained. The reliability of the serialization method is verified. The whole frame of the system is designed according to the requirements of product serialization. The series design system of bottom side unloading mining car product is developed with SolidWorks as CAD platform and VC development tool combined with Access database.
