Abstract

|
A general method to measure a noise of a automobile tire is used of a microphone array.
This method has the weakness that a walled micro-phone array causes a reflection and a diffraction, and so a sampled on a micro-phone array is distorted.
But this weakness is improved by micro-phone which traces a course to a setted up measuring point on a made up cartesian coordinate.
This method requires that micro-phone is accurately moved into a setted up measuring point.
In this paper, a cartesian coordinate type robot for automobile tire noise measuring to search a source of noise is implemented by co-operated with IBM PC/AT (12MH(z)) as a host and a micro-processor 280 as a channel for the
precise movement.
This designed, manufactured and implemented robot system is experimented.
The result has been obtained the pretty good movement on the X,Y coordinate in the full range 2000mm.
