Shock Absorber Testing Machines

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.

Sectors of application:

Shock absorber testing machine for mobile laboratory

The shock absorber testing machine, of the electromechanical type, is placed on a van which is equipped with the necessary equipment to carry out tests on the shock absorbers. This mobile laboratory allows you to work directly following track tests. In preparation for the test, the stroke is manually adjusted by moving the eccentric, then the mounting of a shock absorber on the appropriate attachments and locking the crosspiece in position. You can see the rotation of the eccentric which produces the movement of the stem. Finally, the following tests are programmed on the PC and performed by the machine: -the positioning – force-speed diagram (sweep) -hysteresis cycles
