钛合金管材壁厚自动超声检测装置研制
Development of Automatic Ultrasonic Measuring Device for Wall Thickness of Titanium Alloy Tube

钛合金管材在航天航空、核工业等领域具有广泛应用，且对其壁厚均匀有很高要求，精确高效地检测出各截面壁厚分布可为后续壁厚修正提供良好的指导。因此，本文基于超声波测厚原理，选择全没水浸法的耦合方式，针对管材壁厚分布不均匀以及轧制后管材会出现弯曲等现象进行分析，以便于探头调节为前提进行自动检测装置的设计。结果表明，该装置能够准确检测管材壁厚分布且系统稳定性好，具有良好的可靠性与实用性。
Titanium alloy tubes are widely used in aerospace, nuclear industry and other fields, and the uniformity of wall thickness is strictly required, accurate and efficient detection for distribution of wall thickness in each section can provide a good guidance for correcting wall thickness. Thus this paper presents a coupling method that prob and tube are immersed in water based on the ultrasonic thickness measurement principle, non-uniform distribution of wall thickness of tube and bending after rolling are analyzed in order to facilitate the probe adjustment as the premise, and design the automatic measurement device. The results show that the device can accurately detect the distribution of wall thickness of tube and the system has good stability, reliability and practicability
