On the base of analyzing the development of control system for synthetic rubber press internationally , and combining the development status quo of applied research of reliability engineering of hydraulic systems , to overcome the design limitations of traditional control system for synthetic rubber press and such faults as high energy - consume , long process period and low reliability in the pressing process of synthetic rubber in the post - treatment product line , brand - new design and reliability research are to be carried out for the new control system 通过对目前国内外合成橡胶压块机控制系统发展水平的分析，结合可靠性工程在液压系统中应用研究的发展现状，针对国内合成橡胶后处理生产线上传统橡胶压块机控制系统的设计缺陷及橡胶压制过程中能耗高、工艺周期长、可靠性差等故障现象，对橡胶压块机控制系统进行全新设计和可靠性研究。
The reliability engineering technique of the mechanical system originate the electronics field , now some already issued methods or standards of the design , experiment and analyze for the reliability , mostly set down according to the characteristics that most electronics product failures are of random and the life span obey exponential distribution 机械系统可靠性工程技术起源于电子领域，现已颁发的一些可靠性设计、试验和分析方法或标准，大都是根据电子产品故障多属随机性、寿命服从指数分布等特点制定的。
This thesis establishes three models for a single - unit markov repairable system , and derives some reliability indexes by the method of stochastic process and probability . the thesis is based on the practice problems of maintenance and the idea of ion - channel . some numerical examples done by the mathematical software maple are given to illustrate the results at the end 本文基于维修理论的实际问题,并借助离子通道中的一些理论思想,运用随机过程与概率论的方法研究了可靠性工程中单部件马尔可夫可修系统的建模及在模型建立之后系统的一些可靠性指标的推导与证明,并运用数学软件maple对推导出的结论进行了核实与分析,同时给出了数值示例。
In this paper , on the base of analyzing the reliability operation status and the reliability data of 200mw units with the reliability management information system for jingyuan power plant , the feeble link and the key part of the generation set and system are defined and the corresponding measures are adopted , consequently , is increased the fault ratio of the device we can reduce and enhance security of the power plant , which is an effective method that controls the device reliability by using the mothod of systems engineering , namely plans , organizes , corresponds , controls and supervises the diversified engineering and technic activity of the reliability during the period of the whole device life to realize the reliability aim , minimize the cost of the whole device life and improve the general level of business safety production 本文在应用靖远电厂可靠性管理信息系统对该厂的200mw机组运行状况和可靠性数据进行分析的基础上，确定了发电设备和系统的薄弱环节、关键部位、并采取相应的措施，从而使设备的故障率减少，使电厂的安全性得以提高。这是一种利用系统工程的方法对设备的可靠性进行控制，即对设备全寿命周期中各项可靠性工程技术活动进行规划、组织、协调、控制、监督，以实现确定的可靠性目标，使设备全寿命周期费用最低，提高企业安全生产综合水平的有效方法。
