摘　　要：针对当前航空飞机对线位移传感器应用场景的要求,提出一种集成电气信号和机械指示功能的复合式线位移传感器,并对其中的涡卷弹簧设计原理和电气信号设计原理进行描述,采用理论分析和仿真建模的方式得到最佳的线位移传感器设计方案。另一方面,列举线位移传感器在地面试验和飞行试验过程中遇到的2个典型故障问题,分别是低温试验下钢绳无法回缩的故障和电阻信号跳变的故障,并从故障概述、故障树分析、机理分析和故障解决4个方面进行分析,找到故障原因并提出解决办法。该文所使用的故障分析方法和故障原因对同类型的航空类产品设计提供参考意义,提高设计质量。In response to the current requirements of aviation and aircraft for linear displacement sensor application scenarios,a compound linear displacement sensor integrating electrical signal and mechanical indication functions is proposed,and the design principles of the scroll spring and electrical signal are described.Theoretical analysis and simulation modeling are used to obtain the best linear displacement sensor design scheme.On the other hand,two typical fault problems encountered by linear displacement sensors during ground tests and flight tests are cited,which are the fault that the steel rope cannot retract under low temperature tests and the fault that the resistance signal jumps.The fault summary,fault tree analysis,mechanism analysis and fault resolution are analyzed,and the fault causes are found and solutions are proposed.The fault analysis methods and fault causes used in this paper provide reference significance for the design of similar types of aviation products and improve the design quality.
