[Abstract]:Reliability and maintainability are indispensable concepts in the research of equipment life cycle. Maintainability and reliability are closely related to each other. Both are the factors that determine the effectiveness of equipment or system. In this paper, by establishing the maintenance model of the whole life system based on time-varying reliability, the variation law of reliability and maintainability in the whole life cycle of the system is discussed, and the method of solving the related reliability and maintainability index is studied. And how to get the relevant parameters of the model through the actual engineering data is analyzed. The main contents of this paper are as follows: (1) the basic maintenance theory is studied. Based on time-varying reliability, a life-cycle maintainability model is established. (2) the maintenance interval and reliability calculation of maintenance model based on time-varying reliability are studied. Using model to analyze the reliability of the system. (3) using MATLAB language to write model related calculation program, using C language to compile model calculation interface, to simulate the relevant data in MATLAB environment, The expected function of the main maintainability parameters of the system is obtained. (4) the technical method of how to determine the main parameters of the model through the actual engineering data is studied, and the feasibility of the method is verified by an example. (5) the benefit degree function is introduced. The reliability index is combined with the economic index to judge the limit technical state of the system and to determine the whole life cycle of the system. (6) the model availability is verified. The maintainability of a certain equipment monitoring system is optimized by using the model, and compared with other models, the advantages and disadvantages of the new model are obtained.
