| Abstract: |
| Objective To perform specifically study the assessment of precision retention of training equipment. Methods The precision degradation of training equipment was monitored during the use, and the comprehensive precision index of the training equipment at each monitoring time was calculated, to predict the lifetime of the training equipment. Results Through the regression model of the precision index and time, the failure level and the predicted failure lifetime T忆 of the equipment were obtained, respectively, based on which the precision retention of the training equipment was assessed. Conclusion The precision retention of the training equipment is an important quality index of interest to the users, which has a direct impact on the effectiveness achieved by the training equipment during the operation process. The assessment result of precision retention is also an important reference for the users to determine the reasonable accuracy adjustment and overhaul cycle of the training equipment. |
