Electronics, Mechatronics & Hydraulics Test bench shock absorber

The test bench shock absorber is used to check the damping behavior of shock absorbers in series production.
The shock absorber test stand is designed as a semi-automatic machine with manual loading and automatic test procedure The actuator driven by a linear motor operates the shock absorber with a sinusoidal curve. The test amplitude and test speed are variably adjustable. Different test points can be set during a test cycle. The measurement results are displayed on the screen in tabular and graphical form. The graphical representation of the results is done as a force-distance and force-speed diagram.
The programming of the test procedure takes place in the flexible test plan. The flexible test plan allows maximum freedom in the creation of the test sequences.

The operation of the shock absorber test benchis carried out by a PC software.
