航天推进剂加注系统是型号发射和试验的重要地面设备,作为可修系统,维修性是其主要特征。以维修性理论为依据,运用故障树分析法对系统故障模式进行识别,提出可达性、标准化和模块化设计、安装方法优化、提高测试性、易损件储备、维修制度等提高系统维修性的措施。通过维修性能量化评价,验证措施有效。
Aerospace propellant filling systems are important ground-based equipment for launching and testing models and maintainability is a key feature of repairable systems. Based on the theory of maintainability, the fault tree analysis method is used to identify the system failure mode, and the reachability, standardization and modular design are put forward, the installation method is optimized, the testability, consumables storage and maintenance system are improved, and the maintainability of the system is improved The measure. Through the maintenance performance of quantitative evaluation, validation measures effective.
