Abstract: The vibration quality has been widely used to measure the stability of vehicle operation. In this paper, the healthy condition of the fire robot was determined after the precise Sperling Index of the vibration quality was determined by acceleration and frequency. A method of measuring robot vibration based on virtual instrument technology has also been proposed. The relation between dominant frequency and engine speed has been discussed, and a new divided grades of vibration quality based on the Sperling Index has been found for judging healthy condition of the robot.
Keywords: Fire robot, Sperling index, vibration quality
