Vibration Calculation of Garden Tractor using Solution of Nonlinear Vibration

Abstract

We studied on the theoretical vibration analysis of garden tractor. This analysis used the nonlinear three degree of freedom systems, moreover applied the adapted calculation for experimental garden tractor as the case of high speed, low speed and suspension.
As the results of calculation of vibration amplitude, on some parts of low pressure tire, minimum amplitude curves coincided with the experimental results of previous report. On many parts of low pressure tire and high pressure tire, standard amplitude which is the differential average of maximum and minimum amplitude curve was very good. Therefore, we understood that we could use these curves.
