| 摘要: |
| 以满足民机起落架全寿命周期的安全使用为目标，结合结构、机构、系统可靠性理论，提出了一套完整的民机起落架安全性分析方法。以某型民机前起落架不能放下或放下未锁定故障模式为例，进行了安全性分析，当分析结果不满足安全性指标要求时，则需通过安全性灵敏度分析，开展民机起落架的安全性设计改进。该分析方法适用于飞机设计全过程，可指导起落架设计优化，并可为民机适航取证提供技术支持。 |

| Abstract: |
| The goal of this paper is to meet the safe use of the whole life cycle of civil aircraft landing gear. Based on the theory of structure, mechanism and system reliability, a complete analysis method of safety of civil aircraft landing gear is given. Taking the nose landing gear failure to extend and down-lock as an example, the safety analysis is performed. When the results do not meet the requirements of the safety indicators, improved safety design of civil aircraft landing gear need to be made using sensitivity analysis. This method is application to the whole process of aircraft design. The method can guide the optimal design of landing gear and provide support for airworthiness. |
