| 摘 要： | 维修方案中规定了各种部件的维修类型和维修间隔，由于各部件的维修类型相对固定，所以维修间隔的确定是制定维修方案的关键。针对这种特点，同时为了能更准确的反应部件实际情况，本文采用飞机部件的使用可靠性数据来确定其维修间隔。为此，针对符合威布尔分布的部件，研究了利用中位秩及最小二乘法对两参数威布尔分布的参数进行估计，并根据其寿...

| Abstract: | Maintenance review board report prescribes preventive maintenance task type and interval of the component. Maintenance task types are available in MSG-3 document. Thus it is an important process to determine the maintenance task interval. In this paper, the using data of aircraft components is used to determine maintenance interval. The least square is used to estimation weibull distribution parameter. Then maintenance task interval model is set up. Finally, we used the reliability data of brakes in Boeing 767 as an example to verify the method. |
