- Abstract
Ensuring the reliability of remanufactured machine tools is an effective way to improve customers' recognition to remanufactured machine tools. Based on this, a full state reliability analysis method of remanufactured machine tools based on meta action unit and Markov chain was proposed. The decomposition method of element action unit was introduced to analyze from the part level, and the FMA tree of remanufacturing machine tool was established. According to the characteristics of the remanufacturing machine tool meta action unit system, the full state modeling was carried out. The operation process was divided into the normal state and fault state of the meta action unit. The Markov decision process was introduced. The full state model of the remanufacturing machine tool was established by combining the meta action unit state and the Markov decision process. The model was solved by analytical method, and the reliability was evaluated. Finally, taking the NC turntable of remanufacturing machine tool as an example, the effectiveness and feasibility of this method were verified.
