【摘要】 高压辊磨机作为一种高效、节能型的粉磨设备在水泥行业中已得到广泛应用，并正在向金属矿山选矿行业拓展，其巨大的发展潜力促使其形成产业化、系列化的生产趋势。为解决实际开发设计和系列化定型设计中的关键技术问题，本论文采用基于3D特征造型的CAD技术，对高压辊磨机的主要工作部件——组合式压辊进行设计与分析，实现以先进的科技手段解决关键性技术问题，为该设备的开发研制和推广应用奠定基础，推动其产业化、系列化发展进程。本论文主要内容如下： (1)以三维CAD软件SolidWorks为基础，以特征为桥梁，集成COSMOS／Works、IPA等软件，创建了高压辊磨机组合式压辊设计与分析的系统平台，为CAD技术在组合辊设计过程中的应用提供了实施途径。 (2)从基于特征的零件建模和装配技术的探讨出发，通过实体建模、虚拟装配设计完成组合辊的结构设计；通过对装配体进行静态干涉检查，以检验结构设计的合理性；同时对装配体进行动态模拟设计，拓展了CAD技术的应用领域。 (3)将有限元分析技术应用于组合辊的结构设计过程中，对组合辊的各组成零件按工作状态下的力学模型进行有限元分析，从理论上为产品的结构设计提供有价值的依据，优化各零件的结构、材料性能。 (4)在理论设计与分析的基础上，本论文通过高压辊磨机在姑山矿选厂粉碎铁矿石的工业化运行试验，考核该设备及其组合辊的工作状况。根据现场考察和试验情况，基本上验证了理论设计与分析的可行性和正确性，也发现了一些新问题；同时，对高压辊磨机粉碎铁矿石的粉碎效果和工艺节能性也进行了试验研究，为该技术的进一步研究奠定了基础。 本论文从工程实用角度出发，为高压辊磨机组合辊的开发研制提供了瓶颈技术，该技术的有效实施不但缩短了产品的开发设计周期，提高产品设计质量，降低设计成本，而且为高压辊磨机设备的产业化、系列化发展，加速该设备在金属选矿行业推广应用的进程奠定了技术基础。更多还原

【Abstract】 High-Pressure Grinding Roller (HPGR), as a kind high-efficiency and energy-saving equipment, has been widely applied in cement industry, and is extending to the domain of metal ore mining and beneficiation, the industrialization and series trend will be formed for its tremendous development potential. In this thesis, assembled grinding rollers-the main working section of HPGR are designed and analyzed with CAD technology based on feature 3D solid modeling to solve the important technical problems in term of development and design of the equipment. It will lay a sound foundation for its application, and fast the proceeding of research and development. The main contents of this thesis are as follow:(1) The system platform for design and analysis of the assembled grinding rollers is established based on CAD software-SolidWorks, bridged on feature and aggregated with other softwares such as COSMOS/Works, IPA etc, it offers the method of applying CAD technology in designing the assembled grinding rollers.(2) The structure of assembled grinding rollers is designed through solid modeling and virtual assemble, meanwhile, the structure rationality is tested by checking the static intervention among parts of the assembled grinding rollers, and the application domain of CAD is widened for animated design of the assemble.(3) Finite element analysis technology is applied in the structure design, the component parts of assembled grinding rollers are analyzed in accordance with their working state, the analysis results become the theoretical document for structure design, thus the dimensions and materials of the structure are optimized rationally.(4) On the base of theoretical design and analysis, the working state of HPGR and its assembled grinding rollers are tested through the equipment applied to do serial experiment of crushing ironstone on-the-spot at Gu-Shan mining plant. The results of theoretical design and analysis are proved correct and practical, some new problems appear. Meanwhile, the crushing effect and saving energy of the equipment working in process of grinding ironstone are researched, all these lay a foundation for the further study of the technology.Stating form engineering application, the bottleneck technology is offered to research and development of HPGR’s assembled grinding rollers, its enforcement not only shortens the exploratory period of the new product, enhances its design quality, and reduces its research cost, but also lays a technical base for furthering the development progress of industrialized and serial equipments, hastens the equipments’ application in metal mining for crushing hard ironstone.更多还原
