What exactly is laser vibration analysis? Properly speaking, there will always be some degree of motion whenever there are spinning parts. It truly is unwelcome due to related noise, discomfort, wastage of power and faster wear and tear in moving parts, compromising elements and parts. There will always be a degree of vibration when moving parts are involved. Maybe you could have occasionally felt some juddering within your workplace elevator or escalator in the mall as well as the cause is vibration. As it’s just a fact in almost every single item with moving parts, it could be intriguing to know why it happens and what to do about it.

Vibration or the oscillatory movement of parts in a miniscule scale, in any rotating or oscillating or reciprocating machinery due to inherent ‘imbalances’ existing at one or more points. By imbalance what exactly is meant is that the mass is not distributed equally in all directions. Rotating shafts might have eccentricity, which means the axis of rotation is not perfectly along the axis of weight distribution. There is no cause to get perplexed with all this, because technology is there to help you in detecting the causes, at what exact points these aberrations lie, what’s their extent and how much mass needs to be added or taken out to correct the problem. Such technology is called vibration analysis.

Vibration analysis can be done by several types of equipment, but one of the most modern and simplest to handle is the laser vibration analyzer. This directs a highly focused and low energy laser beam at the potential trouble spot within the rotating motor or other machinery and depending on the shift in frequency of the reflections received, the frequency and mode of vibration as nicely as the mass imbalance is indicated. Lest your eyes glaze over at these technical details, however, rest assured that the matter is quite simple. Indeed, you’ve probably already witnessed just such a procedure already, however unwittingly. Know how you had to watch the mechanic line up and true your wheel balance? Don’t forget that additional weight was added at carefully calculated positions, okay? Well, you that’s it in a nutshell. Everything about laser vibration analysis and the hardware hinges on the specific task at hand. We cannot imagine using the wheel balancing instrument to do the job for an aircraft engine weighing tons and rotating at 30,000 revolutions in a minute, can you?
