Vibration Resistance

What is Vibration Resistance?

In the environmental simulation, products are put under a certain amount of stress to test their suitability for an intended application. Vibration test is a part of the environmental simulation and tests the vibration resistance of components.

Electric parts and devices may be put under different types of mechanical stress during shipment and operation. These stresses include vibration, shock (shock, falling) and permanent shock. The vibration resistance of electric components is to be differentiated from vibration resistance in science of materials.

As part of this test, vibration resistance in a certain frequency which is relevant for the application can be proved. Details for the process of testing can be found in the standard. Some examples are: DIN EN 60068-2-6 and DIN EN 60068-2-64. The test secures the functionality of a device to mechanical stresses lined out in the data sheet.

Areas of Application for Vibration Resistant Devices

The vibration resistance of electric components and devices is a requirement in many applications. Vibrations can be transmitted to adjacent devices by engines and transmissions. Hydraulic drives and valves can be a challenge for vibration resistance of machines and plants. For electromechanical components such as relays and safety switches, the vibration resistance is an indication for the area of application of the component.
