| Research Abstract |
A test equipment is manufactured to determine the motion of a rolling agricultural tire with ground contact in respect to vertical or longitudinal direction. The dynamic characteristics are investigated by changing the number of revolutions of the tire. Next, the vibration characteristics of the agricultural tire are investigated in a state of static and with ground contact by experimental modal analysis. By using obtained results, the influences of vibration characteristics on the dynamic behavior of rolling tire are investigated
