How Vibration Test Systems Work

By Helene Norris


A characteristic quality of all machines that are used in industries is vibration. These machines have to work in a proper manner and this is why vibration test systems must be applied. Sometimes the required levels of vibration may be exceeded. It being a sign of problems, instant action should be applied without delay.

Differentiation between acceptable, normal and emergency vibrations is very crucial as far as machines are concerned. The replacement or servicing of equipment is highly reliant on these three important factors. The stimulation of harsh environmental conditions is done by positioning an object into a machine so as to establish how it will perform under such conditions.

Being able to pass through an environment that is full of stress is one factor that this process tries to establish. The parts of a machine that should be considered useless can also be determined using this very test. This ensures that machines are in good shape and are able to carry out their work properly.

Low frequency brings about hydraulic force which in turn produces vibrations. Electromechanical switches called relays are present in most of the electrical devices. The relays have to be subjected to a test to ensure that they are able to detect vibrations within the machine successfully.

If the above mechanical phenomenon takes place and it is not detected, then this means that the system has considerably failed. This means the device has to be improved to enhance its performance. The machine might function poorly as a result of heavy vibration. This might lead to it getting damaged.

The vibrations should be left for as long as a machine is on and functioning. A machine might take a long time before it is unable to function, and that is why this is vital. An increase in this mechanical phenomenon's intensity is important in order to be certain of the relays ability to perform well.

During the test, there must be secure attachment of sensors. Accuracy of readings is vital and therefore, they must be left attached to the relay device. Most materials, when subjected to high heat, will break easily. The same applies to high levels of this mechanical phenomenon. The subjection of high heat level to equipment is substantial for them to maintain their performance ability when faced with vibrations.

Shock is sometimes experienced as a result of heavy vibration during a test. Permanent damages such as deformation and fractures are at times experienced. Shocks can sometimes lead to fasteners dislodging or relay chattering. In order to find out whether or not the equipment will be able to withstand vibrations, these factors should be considered.

When testing for this its resistance of equipment, the sine and random vibrations must be highly considered. Relay systems with poor design can easily be destroyed by these types of vibrations. The likely level of this mechanical phenomenon should be the main focus and the determining factor when conducting the test. When trying to ensure that equipment are functioning properly without any hiccups, and are able to withstand heavy vibration, vibration test systems are very critical.
