|
摘要
为了能够根据可靠性状态制定无人机零部件的维修维护策略,提出一种基于可靠性评估的无人机零部件维修决策方法。该方法首先建立无人机零部件的可靠性评估模型,根据故障样本得到其退化过程参数,进而求解可靠性指标,根据阈值分析和可靠性评估结果进行维修时间决策。以实际使用中的无人机故障情况为例,按所提方法进行了仿真分析,结果表明该方法能够对无人机零部件的可靠性进行有效评估,制定相应的维修策略,对保证无人机的正常服役与使用具有重要意义。
In order to formulate maintenance strategy for UAV parts based on reliability status,a maintenance decision-making method for unmanned aerial vehicle components based on reliability evaluation is proposed in this paper. Firstly,the reliability evaluation model of UAV components is established. Secondly,by combining with the fault record samples,the degradation process parameters are obtained and then the reliability parameters can be calculated. Based on the threshold analysis and reliability evaluation results,the relevant maintenance decision can be made. The fault data of UAV components in practical use are taken as examples to verify the validity of the proposed method. The results show that the proposed method can evaluate the reliability of same type of UAV components in large quantities and make the maintenance strategy. It shows significance to ensure the normal service and the use of the UAV.
