某航空轮胎磨损深度的灰色预测

为揭示某小型活塞式固定翼飞机装备的航空轮胎磨损深度的变化规律,本文分析了导致航空轮胎磨损的影响因素,得出航空轮胎磨损深度是一个随时间变化的随机量。在此基础上,利用灰色理论建立轮胎磨损深度的灰色预测模型,并对预测模型精度进行实际数据验证。结果表明:轮胎磨损深度的预测结果准确性高,建立的灰色预测模型能较好地揭示航空轮胎磨损深度随时间的变化规律。

In order to reveal the variation rule of wear rate for a little piston airplane’s tire,the influencing factors of wear were analyzed,which show that the wear rate is a random variables,it will change with used time.On this basis,the grey prediction model of wear rate was established according to grey theory,the accuracy of prediction mode was verified by experiment.The results show that the prediction results of wear rate for tire has a high precision,the grey prediction model can better reveal variation rule of wear rate with used time.
