压电超声管道腐蚀检测传感器支撑结构振动特性
|
摘要
压电超声管道腐蚀检测器是一种利用超声波对长输管道进行在役腐蚀检测的内检测设备,结构合理的压电超声传感器支撑结构是管道腐蚀检测成功的前提。采用基于有限单元法的结构分析软件对支撑结构三维模型进行预应力状态下的模态分析,结果表明:预应力会使传感器支撑结构的固有频率高于自然状态下的固有频率,但更接近于结构的真实固有频率。通过支撑结构振动测试试验,验证了仿真分析的可靠性,同时发现试验结果与仿真结果的误差主要来源于仿真过程中对支撑结构模型的简化。研究结果对于压电超声管道腐蚀检测器的整机研制具有重要的参考价值。(图6,表3,参23)
Piezoelectric ultrasonic pipeline corrosion detector is a kind of internal testing equipment which makes use of ultrasonic wave to detect the corrosion situations of in-service long-distance pipelines. A structurally reasonable supporting structure of piezoelectric ultrasonic detector is the prerequisite for the success of pipeline corrosion detection. In this paper,the modal analysis was conducted on the 3D model of the supporting structure under the prestress state by the FEM based structure analysis software. It is indicated that the natural frequency of the supporting structure under the effect of prestress is higher than that in the natural state, but it is closer to the true natural frequency of the structure. Then, vibration test was carried out on the supporting structure. And it is verified that the simulation analysis is reliable and the error between the experimental result and the simulation result is mainly derived from the simplification of the supporting structure model. In conclusion, the research results are of great significance to the research and development of integral piezoelectric ultrasonic pipeline corrosion detector.(6 Figures, 3 Tables, 23 References)
