STUDY ON VIBRATION CHARACTERISTICS ON MEASURING METHOD FOR FARM MACHINERY

Driving simulation using the motion equations based on the 3-dimension al dynamic model of the rubber crawler traction system was performed u nder various conditions. The location arrangement of track rollers was estimated through the experimental results and driving simulation. Co mponents of vibrational acceleration of the rubber crawler traction sy stem with 6 degrees of freedom could be measured individually and accu rately using the new measuring method proposed by the authors. Accurac y of translational components of vibrational acceleration improved rem arkably compared with the conventional measuring method. Motion equati ons and frequency transfer function of a riding tractor with rotary ti llage equipment were proposed. Simulated data of frequency response we re compared with measured data of forced vibration experiment to deter mine the validity for tractor's dynamic model.
