- Abstract
- This study deals with the ultrasonic propagation characteristics according to the wall in a linear waveguide combined with an ultrasonic sensor for distance measurement. The purpose is to reduce the wall reflection by a rough surface because the wave reflecting on a smooth wall of the waveguide would interfere with straightly travelling wave. Wedges were designed on the waveguide wall. Ultrasonic wave propagation in a linear waveguide with the wedged wall was analyzed by finite elements, and the magnitude of the wave signals was evaluated according to the wedge angle for distance measurement. Experiments were carried out and the analysis results were verified by comparison. Wedge angle maximizing the wave signal magnitude was obtained.
