Mechanical tests

As well as climatic tests, mechanical tests are essential during mechanical structure or functional equipment qualification. Arenius laboratory has materials means (3 electrodynamics vibrations systems) and tests software (sine, random, sine dwel, sine on random, random on random, mechanical shock, CRS shock test software) to reproduce automotive, rail, aeronautical, military mechanical conditions…
In addition to qualification tests carry out, our design office can realize your vibrations mechanical interfaces and mechanical endurance benches (Labview software programming, CAD, modal analysis...)

Mechanical design office

Vibrations tests mechanical interfaces design is a leading step for reliable tests results, fixtures must ensure physical strength transmissibility without increasing tests severity because of resonance frequencies. Our laboratory can manage complex mechanical interfaces design for your vibrations tests. Services include drawings design, modal analysis, and fixtures manufacturing with qualified subcontractors.

Our mechanical design office develop also mechanical endurance benches according to your specifications tests. Our philosophy is to develop less expensive solutions particularly when only one qualification test is requested. Our service include control and measurements software programming (Labview MMI), parts benches industrials drawings, and benches conception.
