What do we mean by mechanical-dynamic tests?
With our mechanical-dynamic tests, we examine the loads on components or complete systems caused by vibrations and mechanical shocks - up to the point of fatigue or even breakage. In this way, we can simulate the use of components or assemblies in high-vibration locations, ranging from the engine compartment of motor vehicles to severe earthquakes. With shock tests, we can simulate strong impulses, such as those caused when a wagon is coupled to a locomotive.
We perform mechanical-dynamic tests in three categories: sinusoidal vibrations, broadband noise and shocks. In addition, we implement tests in the field of resonance search. The aim of this test is to determine the natural resonance and to stress it in accordance with the application. To do this, we generate a sinusoidal oscillation in the area of the natural resonance and hold it for a fixed duration. This allows us to detect fatigue and fractures in the test specimen and to draw conclusions about the service life of your product.
Our experienced engineers will be happy to develop your own test frame using CAD software and check it in an FEM simulation. We manufacture your test frames in our own laboratory workshop using modern CNC technology and welding processes.
