Durability and Performance Test
This test is essentially a fatigue test that uses a vibration controller to generate a vibration signal, which can be either constant or with a variable frequency (sweeping frequency between two limit values). The amplifier converts this signal into a suitable voltage and current for the shaker, allowing the desired vibrations to be applied to the test component. Typically, the component must undergo vibrations for a specified number of hours in various directions, after which potential failures are assessed.
Generally, specific standards exist for components mounted on vibrating equipment, such as vehicles, which define the amplitude, frequency, and type of excitation.
For performance testing, the same equipment and setup used in durability tests are employed to study the vibrational behavior of the component. Instruments like a stroboscope are utilized to observe the movements and deformations occurring in the component.
