| Abstract: |
| Objective Toenhance the risk resistance of the new generation of launch vehicle liquid propellant pressurization and low-temperature vibration test of the pipeline, reduce risks, and improve the effectiveness and safety of the pipeline in low temperature + internal pressure + vibration and other composite environmental tests. Methods Based on the knowledge of project risk management, the risk factors of each component of the test system were decomposed and identified; and the hazard causes and harmful consequences of each risk factor were evaluated. Based on the analysis, methods and measures for effectively reducing risks were proposed. Results Through the identification of risks, risk assessment and risk prevention methods and measures, the test system was optimized on the basis of meeting the test requirements; and the ability to cope with such test risks was strengthened to effectively improve the test equipment and reduce the probability of occurrence of risks. It laid a solid foundation for successful ground-based composite environment test of the new generation of launch vehicle pressurized pipelines. Conclusion The application of risk management in the environmental simulation test of a new generation of launch vehicle booster pipelines is studied. Risk control can effectively reduce the probability of various risks in the test, including risk identification and analysis of risks and risk management of project. It can not only provide more reliable protection for the safety of personnel, equipment and products, but also improve the efficiency of environmental simulation tests. |
