Product serial number
Dynamic fatigue testing machine
The creep test bench mainly includes mechanical structure, weights, servo cylinders, sub-stations, additional air chambers, and control systems. It is used for various performance tests of rail passenger car air springs. Dynamic test load: 30T, maximum loading frequency: 15Hz, loading Accuracy: ≤±0.5%FS.
The main function:
Creep test: test the creep properties of air springs, steel springs, and rubber elastic components;
Damping coefficient test: test the damping coefficient of the air spring;
Vertical dynamic performance test: test the vertical dynamic performance of air springs, steel springs, and rubber elastic components;
Vertical static performance test: Test the vertical static performance of air springs, steel springs, and rubber elastic components.
