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 is dynamic wheel load, the horizontal axis of cylindrical plane bearing is time, the dynamic wheel load at resonance is accurately measured. Calculate display the percentage of information dynamic wheel load static data wheel load the error of coaxial output wheel load percentage.

（2） The diagnostic standard for the characteristics of shock absorbers in operation (GB 18565-2001 comprehensive performance requirements inspection methods for operating vehicles) requires that for passenger vehicles with larger design scheme speed of 100km / h axle load quality of less than 1505kg, the alkali shock test bench shall be used to inspect the shock avoidance characteristics in accordance with the specified method, the digestibility of the wheels of the vehicle to be inspected under the external excitation vibration shall be measured, That is to say, the minimum dynamic wheel vertical load static data of the car to be tested, the percentage value of the wheel vertical load (also known as the wheel wheel grounding device performance index value) shall be less than 40%, the difference of the digestibility of the left right wheels with coaxial output shall exceed 15%. .
