SHOCK ABSORBER TESTING MACHINES can be divided into two main groups:
Electromechanical type driven by a direct current motor or a brushless motor and with crank connecting rod mechanism, with adjustable stroke, which transforms the rotary motion into a sinusoidal one. By means of the potentiometer, the speed transducer and load cells, data for the characterization of the shock absorber are detected.
Hydraulic type with servo-controlled actuator suitable for high-speed levels (max 3 m/sec), which detects displacement, speed and load for the characterization of the shock absorber and creates files in Windows environment with diagrams of force-displacement, force-speed, sweep, force-temperature (applying a sensor in the shock absorber). Which can be used for fatigue tests with particular waveforms programmable in block diagrams.
We can build multi-station machines and machines with tilting mechanism to simulate the working position of the shock absorber.
