How To Determine Equipment Functionality Through Vibration Test Systems

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.

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.

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.

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.

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.
