How Vibration Test Systems Work

By Helene Norris


Vibrations are virtually experienced by almost all types of industrial equipment. In relation to the functionality of these machines, vibration test systems must be put in place. An increase in vibration above the needed level may be experienced at times. Immediate attention should be paid to such instances, as this might be an indication 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.

The procedure is used in determining whether a machine can be able to withstand environmental conditions that are stressful. Another reason why this test is very important is that it is able to establish which of the machine parts need to be rendered of no more use. The result is that proper functionality of machines is ensured in the long run.

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.

A failure is established if this mechanical phenomenon occurs and there is detection of changes; and this leads to device enhancement to improve its future functionality. Heavy vibration might result in poor functioning of the machine. Damage of equipment might occur in such cases.

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.

Sensors must be attached securely throughout the test. In order to get readings that are accurate, they should be left on the relay device. Just like intense heat, intense vibrations also result in the damage and breaking of most material. It is therefore vital that the equipment be exposed to the same levels of heat so that they are able to perform well in case they ever face intense 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.

Sine and random vibrations are crucial when it comes to establishing equipment vibration resistance. There is a high possibility of the destruction of relay systems that have poorly been designed. The main factor to be used in determining equipment resistance when the test is being performed is vibration. Equipment should be able to perform well and be able to hold up for long when exposed to this mechanical phenomenon, and hence, vibration test systems are very useful.
