Equipment Summary:

Computer Control Air Spring Fatigue Testing Equipment is the use of microcomputer electro-hydraulic 

servo drive device of power, adopts the United States MOOG system of  electro-hydraulic servo control

valve hydraulic servo cylinder control, which can move up and down, repeated pressure of air spring,the

maximum load is 80KN,with a frequency of 3HZ and a half the maximum compression values for amplitude

repeated telescopic motion. 

The system consists of computer control, dynamic test and static test, stable performance, low failure rate.

 HZ-7813 computer control air spring fatigue testing machine with action cylinder  hydraulic servo system,

 is mainly used for all kinds of automobile fatigue test of air spring products. By fatigue test of 3000000 times

 of car suspension spring.The 3HZ frequency and allowable half maximum compression values for amplitude

repeated stretching vibration. Continuous 30 days repeated movement.
