摘要
气动阀门已应用于各种工业领域,气动阀门出现故障将对整个系统的运行造成直接影响,因此对气动阀门进行在线监测非常必要。目前,对于气动阀门位移监测的相关研究较少。本文使用溶液浸渍法设计了具有大应变范围、良好动态反应能力的CNT/TPU柔性应变传感器,讨论了传感器的传感机制以及工作原理并对传感器进行了性能测试。在对气动阀门位移监测过程中,该传感器运行稳定。结果表明,该传感器可以对服役过程中的气动阀门进行实时相对位移监测。
Pneumatic valves are currently used in various industrial fields,but there are still few studies on displacement monitoring of pneumatic valves.In order to understand the relative displacement change of an aviation pneumatic valve in service,this paper adopts,the solution immersion method to design a CNT/TPU flexible strain sensor with a large strain range and good dynamic response capability.The sensing mechanism and working principle of the sensor are discussed.In the process of monitoring the displacement of the pneumatic valve,the sensor operates stably.The results show that the sensor can perform real-time relative displacement monitoring of the pneumatic valve during service.
