【摘要】：滚筒采煤机是综采工作面原煤生产和实现高产高效矿井的核心设备，它的可靠性直接影响着矿井的自动化与智能化水平。由于滚筒采煤机的结构系统相当复杂，工作条件极其恶劣，其可靠性水平又被认为是评价其优劣的核心指标。为了规范滚筒采煤机可靠性数据的搜集、统计、分析，实现其可靠性指标的计算，构建一个完整的滚筒采煤机可靠性工程平台，用于采煤机的可靠性信息的管理，提高了采煤机的可靠性水平。论文建立了采煤机可靠性工程体系结构，分析采煤机可靠性指标，之后对采煤机的关键部件进行FTA分析、FMECA分析，对不同的故障类型，提出了采煤机的可靠性保障措施。论文应用产品的全寿命周期理论与可靠性工程技术，对采煤机在设计、制造、贮存、安装调试、使用维护以及报废的全寿命周期中可靠性信息进行分析研究。对其全寿命周期中的各个阶段，进行分阶段、分层次的可靠性管理研究。根据对国内采煤机生产制造企业的需求分析，在ASP.NET的构架下，以C#为汇编语言，Microsoft SQLServer2008为数据库，，构建了一个滚筒采煤机可靠性工程平台。该平台的作用是为滚筒采煤机的生产制造企业与使用单位进行有效的可靠性资料共享，可以实现可靠性数据的实时查询、添加、删除以及报表打印等功能，对全寿命周期下的滚筒采煤机可靠性信息进行有效的管理。本课题的最终目的是建立一个完整的滚筒采煤机可靠性工程平台，为煤炭生产企业与煤机制造企业搭建一个共享的可靠性信息服务平台，增强采煤机制造企业和使用企业对采煤机可靠性信息的管理，切实提高国产采煤机的可靠性水平。
[Abstract]:Drum shearer is the core equipment for the production of raw coal and the realization of high yield and high efficiency in fully mechanized coal mining face. Its reliability directly affects the level of automation and intelligence of the mine.Because the structure system of drum shearer is quite complex and the working conditions are very bad, its reliability level is considered as the core index to evaluate its merits and demerits.In order to standardize the collection, statistics, analysis and calculation of reliability index of drum shearer, a complete reliability engineering platform of drum shearer is constructed, which can be used to manage the reliability information of shearer.The reliability level of shearer is improved.In this paper, the reliability engineering system structure of shearer is established, and the reliability index of shearer is analyzed. After that, the key components of shearer are analyzed by FTA and the reliability guarantee measures of shearer are put forward for different fault types.In this paper, the reliability information of shearer in design, manufacture, storage, installation and commissioning, use and maintenance as well as end-of-life life cycle is analyzed and studied by using the theory of product life cycle and reliability engineering technology.The reliability management of the whole life cycle is studied by stages and levels.According to the demand analysis of domestic shearer manufacturing enterprises, a reliability engineering platform of drum shearer is constructed with C # as assembly language and Microsoft SQLServer2008 as database under the framework of ASP.NET.The function of the platform is to share the reliability data between the production and manufacturing enterprises of the drum shearer and the users, and to realize the functions of real-time query, adding, deleting and printing of the reliability data, etc.The reliability information of drum shearer under the whole life cycle is managed effectively.The ultimate purpose of this project is to establish a complete reliability engineering platform for drum shearer, and to build a shared reliability information service platform for coal production enterprises and coal machine manufacturing enterprises.To strengthen the management of shearer reliability information in shearer manufacturing enterprises and use enterprises, and to improve the reliability level of domestic shearer.
