摘要
机载设备拆装时间是重要的维修性设计指标,是选择或优化设计方案的重要参数。提出一种以过程仿真模型为基础,综合考虑维修作业复杂度和维修工效评估结果的拆装时间综合评估方法。首先,将机载设备拆装过程分解为基础维修活动单元,规划仿真过程并建立仿真模型;然后,使用模特分析法分析基础维修活动时间,并根据维修作业复杂度与维修工效综合评估结果确定维修时间修正系数,修正基础维修活动时间;最后,根据基础维修活动时间和工作流程评估机载设备拆装时间,并以飞机发动机拆卸时间分析为例进行应用验证。结果表明:该方法可对机载设备拆装时间进行准确评估,能够满足飞机研制的需要。
The removal and installation time of airborne equipment,is not only an important maintainability design index,but also an important parameter to select or optimize the design scheme.A comprehensive evaluation method is presented,which is based on the process simulation model and integrates the evaluation results of maintenance complexity and maintenance ergonomics analysis.Firstly,the disassembly and installation process is decomposed into basic maintenance activities,and process simulation model is created.Then by using modolar arrangement of predetermind time standard(MODAPTS)the basic maintenance activities time is evaluated.Using the coefficient,which is determined by the comprehensive evaluation results of maintenance complexity and maintenance ergonomics analysis,the basic maintenance activities time is corrected.Finally,the disassembly and installation time is evaluated according to basic maintenance activities time and maintenance work process analysis.The method is verified by a case of evaluating engine removal time.The result shows that,the method can be used to accurately evaluate the removal and installation time of airborne equipment,and can meet the needs of aircraft development.
