| 摘 要： | 在对液体火箭发动机试验台推进剂加注系统进行结构分析的基础上,对加注系统进行模块化分解,建立其工作过程模型,分析了动态系统中故障注入的方式,对加注系统的两种典型故障进行了故障建模与仿真分析,仿真结果很好地描述了故障状态下加注系统的工作性能,通过分析仿真结果能进一步丰富和完善试验台故障知识库。Abstract：Based on the structural analysis for LRE test-bed propellant filling system. The filling system was modularized and its working model was built. The method of injecting fault was analyzed. Two typical fault modes were injected into model and the simulation results were analyzed. The results described preferably filling system＇s working capability in fault condition. The simulation results and analysis can also be used to enrich and perfect the fault knowledge base of test-bed.

| Abstract: | Based on the structural analysis for LRE test-bed propellant filling system. The filling system was modularized and its working model was built. The method of injecting fault was analyzed. Two typical fault modes were injected into model and the simulation results were analyzed. The results described preferably filling system＇s working capability in fault condition. The simulation results and analysis can also be used to enrich and perfect the fault knowledge base of test-bed. |
