【摘要】：液压支架是综采工作面最重要的设备之一,它起着控制矿山压力,维护作业空间的作用,其可靠性直接关系着生产效率和人员安全。长期以来,由于技术和观念上的落后,我国对液压支架的可靠性研究比较缺乏,这在很大程度上制约了支架制造厂商技术上的进步,也影响了煤矿工作安全高效进行,因此,有必要从设计、制造、使用、管理等各个方面,全面研究液压支架可靠性,并将其理论用科学合理的工具和方法应用于制造厂商和使用单位,从而实现液压支架可靠性的全面提高。本论文以可靠性工程相关理论为基础,首先对液压支架进行了组成结构和工作原理的介绍,建立了系统和单元两个层面的可靠性模型,并用FMECA、FTA及FRACAS三种方法对其进行了可靠性分析;其次,提出以全寿命周期理论和液压支架寿命状况模糊综合评价来指导支架的可靠性管理,同时给出了相应的管理措施;最后,采取Java语言,结合MySQL数据库,运用多种软件技术,开发了液压支架可靠性工程平台,将可靠性分析与管理整个体系纳入平台功能中,而且通过反复的测试和调试,实现了平台准确稳定运行。液压支架可靠性工程平台的构建,一方面纳入和展现了液压支架可靠性方面的研究成果,另一方面,也利于相关理论在支架制造企业,使用企业的应用,保证了液压支架可靠性的不断提升,有着一定的工程意义。
[Abstract]:Hydraulic support is one of the most important equipment in fully mechanized mining face. It plays the role of controlling mine pressure and maintaining working space. Its reliability is directly related to production efficiency and personnel safety for a long time. Because of the backwardness of technology and concept, the research on the reliability of the hydraulic support in our country is lack, which restricts the technical progress of the support manufacturer to a great extent, and also affects the work safety and efficiency of the coal mine. Therefore, it is necessary to comprehensively study the reliability of hydraulic support from the aspects of design, manufacture, use and management, and apply its theory to manufacturers and users with scientific and reasonable tools and methods. In order to achieve the overall improvement of the reliability of hydraulic support. Based on the theory of reliability engineering, this paper first introduces the structure and working principle of the hydraulic support. The reliability models of system and unit are established, and the reliability analysis is carried out by using FMECA FTA and FRACAS. Secondly, the life cycle theory and fuzzy comprehensive evaluation of the life condition of the hydraulic support are proposed to guide the reliability management of the support, and the corresponding management measures are given. Finally, the reliability engineering platform of hydraulic support is developed by using Java language, MySQL database and many software technologies. The whole system of reliability analysis and management is brought into the function of the platform. And through repeated testing and debugging, the platform to achieve accurate and stable operation. The construction of hydraulic support reliability engineering platform, on the one hand includes and shows the research results of the reliability of hydraulic support, on the other hand. It is also conducive to the application of related theories in the support manufacturing enterprises and enterprises, which ensures the continuous improvement of the reliability of the hydraulic support, and has a certain engineering significance.
