Clarification of vibration generation mechanism of agricultural machinery by identification of lug excitation force

制造了一种测试设备，用于确定滚动农用轮胎在垂直或纵向上与地面接触时的运动。通过改变轮胎的转数来研究轮胎的动态特性。其次，通过试验模态分析，研究了农用轮胎在静态和与地面接触状态下的振动特性。利用所得结果，研究了振动特性对滚动轮胎动态特性的影响。

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
