Abstract:

Performance testing is an important mean to ensure the reliability of equipment. Early maintenance models are based on periodic detection research, which will not be able to reflect the actual work of the equipment very well. Besides, the sources of the date are life date, which have less data samples and credibility is not high. For the equipment which degradation process is in accordance with the Wiener process, a maintenance decision model presented before detection and regular detection is proposed. First of all, the degradation model based on the wiener process is made, and the concept of variable points to get the life distribution is introduced. Finally, according to the proposed maintenance decision model, we determine the optimal inspection interval of equipment.
