在阐明飞机舱门系统启动工作原理的基础上,重点考虑舱门所需克服气密载荷产生的密封带摩擦力的大小及其分散性的影响,构建了舱门意外打开及启动的可靠性分析模型,提出了相应的基于气密载荷作用的飞机舱门可靠性分析方法。以某型飞机舱门机构为例,作了具体的算例阐明,分析方法与结果可为舱门设计提供参考。
On the basis of illustrating the working principle of the aircraft door system, the importance of the frictional force of the sealing tape produced by the airtight load to cover the door is considered. The reliability analysis of the accidental opening and starting of the door is established Model, a corresponding reliability analysis method of aircraft hatch based on airtight load is proposed. Taking a plane door mechanism as an example, a concrete example is made to clarify that the analysis methods and results can provide a reference for the design of the door.
