Abstract
Recently, noncontact method for measuring cylinder configurations are required in industry. This paper reports the development of a new method for measuring cylinder configurations, using sound signal without contacting the contour surface. This method is based on the fact that the phases of sound waves scattered by a cylinder are delayed according to the diameter of the cylinder. Experiments were performed for various cylinder configurations formed by single and plural periodical deflection, using a loudspeaker, microphone and FFT-analyzer. It was found that the phase delays of sound waves were periodically changed according to the revolution of the cylinder, and the period between the phase delay and cylinder deflection was in good agreement. In addition, the angle of phase delay was linearly proportional to the magnitude of deflection.
