Measurement of 6 Degrees of Freedom Components of Acceleration in Rubber Crawler System

Abstract

The vibration of agricultural machines which are fitted with rubber crawlers is caused by the unevenness of ground, attached devices and other factors such as the arrangement of track rollers and the lug phase of right and left side rubber crawlers. To grasp the vibration characteristics of the rubber crawler system, it is necessary to measure the translational and rotational acceleration at the center of gravity. The measurement method using 9 units of accelerometers was previously reported. In this paper, the expanded method of measurement using 12 units of accelerometers and its advantages are reported. The acceleration of the rubber crawler system was measured by the new method, and the acceleration characteristics due to the arrangement of track rollers as well as the lug phases were clarified.
