Imaging of Adhesive Regions between Steel Plates by Focus Type Air-coupled Ultrasonic Technique
フォーカス型空中超音波法による 鋼板間接着剤塗布領域の画像化
The authors' previous study showed that images of adhesive regions between auto body steel sheets can be obtained using air-coupled ultrasonic sensors in oblique beam setting. This study introduced focus type sensors to improve spatial resolution and to reduce spaces requiring sensor arrangement. First, flat type and focus type sensors were compared through transmission tests. Second, through the imaging tests of square holes with various sizes, it was confirmed that spatial resolution was improved using focus type sensors. Images of adhesive regions were then obtained with high resolution by scanning the focus type sensors. 前報では,車体鋼板間の接着領域の画像を空中超音波センサの斜角入射により得られることを示した.本研究では,空間分解能を向上させ,センサ設置に必要な空間を小さくする目的でフォーカス型センサを導入した.最初に透過試験によりフラット型とフォーカス型センサの比較を行った.次に,様々なサイズの四角穴の画像化テストを行い,フォーカス型センサにより空間分解能が向上していることを示した.最後にフォーカス型センサを用いて接着領域の画像を高分解能で取得した.
