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.

It is essential for to be able to tell the difference between vibrations that are acceptable, normal or that which requires immediate action. This will be important so as to replace or service the affected equipment. Its testing involves fixing an object into a machine which will then stimulate some of the harsh experiences it might come across in a real environment.

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.

Vibrations are produced by hydraulic force which is as a result of low frequency testing. Most gadgets that are electrical have electromechanical switches known as relays. To be able to establish the vibrations that may occur within the machine, the relays have to pass through a test.

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.

As long as the machine is in operation, the duration for testing vibrations should be as continuous as possible. This should be so because a device's working condition might take long before it breaks down. To be sure of the relays' holding up capacity, the intensity of the vibrations should be increased.

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.

During the testing of this mechanical phenomenon, it is important to note that heavy vibration can sometimes result in shock. The outcome may be a broken bone or deformation of body parts which might sometimes be permanent. Shocks can lead to dislodgement of fasteners or chattering of relays. These factors should be put into consideration during the testing to establish whether the equipment will be able to hold up.

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.
