초음파 유도관에서 꺾임부 형상에 따른 파동 전파

초록

This study deals with wave propagation based on the elbow shape in a linear waveguide coupled with an ultrasonic sensor. The elbow was introduced to reduce the waveguide length. Three elbow shapes were designed and their wave propagation performance was evaluated. The received wave was monitored, and its amplitude was evaluated using finite element analysis for ultrasonic propagation. Prototypes were manufactured using a 3D printer, and an ultrasonic reflection experiment was conducted to compare the analysis results and verify the similar tendencies. An ‘L’ shaped waveguide with a circular elbow with curvature exhibited the best performance.
