Taking the CF700 tractor as research object

design and build up tractor vehicle vibration acceleration test system

measure tractor front and rear axle vertical acceleration as well as seats and cabin floor vertical

transverse and longitudinal vibration acceleration. Seats and cabin floor position joint acceleration RMS are calculated

and vertical and pitching angle vibration acceleration and PSD of tractor centroid are obtained through tractor geometric relation. The results show that the tractor vibration acceleration increases with the increase of speed

the front axle acceleration is biggest

the vertical acceleration of seat and cabin floor position is bigger than other direction and the joint acceleration RMS is greater than the s

tandard of body feels uncomfortable. The acceleration PSD are concentrated in 3

5 Hz. The study provides important basis for the later development of tractor vibration reduction design.
