3. The way to test the characteristics of Chengzhen with the test bench

(1) Car tire specifications standard air pressure should meet the standard value, the car is fully loaded, no passengers.

(2) Drive the wheels of each axle of the car onto the demand reduction inspection bench, so that the tire is located on the central government part of the counter top, the driver leaves the vehicle.

(3) Start the test bench, so that the vibrator drives the suspension to cause vibration, so that the vibration frequency is increased to the natural frequency beyond the vibration.

(4) After the common shock point, the excitation peak is closed the vibration frequency is reduced.

(5) Record the vibration curve of attenuation coefficient, the longitudinal axis of shock absorber bearing price is dynamic wheel load, the abscissa axis is time, so as to accurately measure the dynamic wheel load at resonance. Calculate display the percentage of information dynamic wheel load static data wheel load the error of coaxial output wheel load percentage.

（2） According to the diagnostic standard for the characteristics of shock absorbers in service (GB 18565-2001) comprehensive performance requirements test methods for operating vehicles, the ATSL shock absorber bearing shall be used in accordance with the specified method for the passenger vehicle with a larger design scheme speed of 100km / h axle load quality of less than 1505kg To carry out the test of shock absorption characteristics, the digestibility of the wheels of the vehicle to be inspected under the external excitation vibration, that is, the minimum dynamic vertical load of the tested car wheel the percentage value of the static data of the vertical load of the wheel (also known as the wheel grounding device performance index value) should be less than 40%, the difference of the digestibility of the left right wheels with coaxial output should be more than 15%. .
