APPARATUS FOR MEASURING TIRE STANDING WAVE CAPABLE OF MINIMIZING MEASUREMENT ERROR

摘要

PURPOSE: An apparatus for measuring a tire standing wave is provided to precisely analyze a size of a tire standing wave while minimizing an error of measurement data. CONSTITUTION: An apparatus for measuring a tire standing wave includes a drum(2) for supplying a load to a tire(1). A sensor box(4) having laser sensors is connected to a computer(5). The sensor box(4) is separated from the rotating tire(1) in order to measure a standing wave phenomenon. A plurality of laser sensors is vertically and horizontally aligned in the sensor box(4) in order to measure a distance. A horizontal direction of the sensor box(4) is used to measure a circumferential transformation. A vertical direction of the sensor box(4) is used to measure a widthwise transformation.
