How To Determine Equipment Functionality Through Vibration Test Systems

By Helene Norris


All industrial machines are known to have a vibrating quality. Vibration test systems are very vital in maintenance when it come to the proper functioning of these machines. Sometimes, this mechanical phenomenon may increase beyond the required level. This calls for instant action because it may be a sign of trouble.

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.

One common application of the testing is to find out if a certain product is able to withstand stressful environmental situations. It is also commonly used in determining which part or parts of a product should be rendered useless. This helps in the proper functioning of machines.

It is important to note that low frequency testing applies hydraulic force in order to produce vibrations. Many electrical devices contain relays, which are basically electromechanical switches. They must go through a test for this mechanical phenomenon which causes a stimulation of the vibrations that may be experienced within the equipment.

If this mechanical phenomenon occurs and any slight change is detected, the test is termed as a failure which will prompt the improvement of the device to avoid future malfunction. This might come about due to heavy vibration. Equipment can be subjected to damage if this occurs.

The vibration duration for the testers should be for as long as the relay device is in operation. This is because it might take a substantial amount of time before a device loses its functionality. This mechanical phenomenon's intensity for the testing should be high in order to be certain that the relays will be in a position to handle it.

There must be secure attachment of sensors during the test. They should be left on the relay equipment so as to be able to achieve accuracy with the readings. When most materials are subjected to heat, they break easily if they are exposed to intense vibration. In this regard, the equipment should also be subjected to the same heat level to ensure that they will continue functioning properly even when they encounter heavy 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.

Finally, both sine and random vibration must be considered when testing for the resistance of this mechanical phenomenon in equipment. They can erode the relay systems that are not properly designed. The testing should focus on the levels of this mechanical phenomenon that are highly likely to happen. Vibration test systems are therefore very critical when it come to ensuring proper functioning and maintenance of equipment.
