Vibration roller control device, control method and vibration roller

摘要

PROBLEM TO BE SOLVED: To provide a control device, a control method and a vibration roller of a vibration roller capable of more reliably giving a desired vibration to a newly installed asphalt road surface while preventing damage to an existing asphalt road surface at the time of construction of asphalt pavement. .. SOLUTION: Vibration shafts X1 and X2 having eccentric weights Y1 and Y2 provided inside front wheels and rear wheels in a traveling direction are rotated by vibration motors M3 and M4 to vibrate the front wheels and rear wheels. The vibration roller control device 1 to be generated includes a front wheel vibration start signal output unit 3 that outputs a front wheel vibration start signal that starts vibration of the front wheels so as to vibrate the road surface to be constructed of a unit length at a predetermined number of times. The calculation unit 4 that calculates the rear wheel vibration start timing based on the time width required from the start of vibration of the rear wheel to the vibration at a frequency that can give vibration to the road surface to be constructed a predetermined number of times, and the rear It is provided with a rear wheel vibration start signal output unit 5 that outputs a rear wheel vibration start signal that starts the vibration of the rear wheels at the wheel vibration start timing.
