What’s laser vibration analysis? Properly speaking, there will always be some degree of motion whenever there are spinning parts. It really is awful because of associated noise, discomfort, wastage of energy and quicker wear and tear in moving parts, compromising components and parts. There will always be a degree of vibration when moving parts are involved. Possibly you may have at times felt some juddering within your office elevator or escalator inside the mall as well as the cause is vibration. As it’s just a fact in nearly each item with moving parts, it will be interesting to know why it occurs and what can be done 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’s meant is that the mass is not distributed equally in all directions. Rotating shafts may possibly 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 is their extent and how much mass needs to be added or taken out to correct the problem. Thus, vibration analysis.
Vibration analysis is possible via any number of methods and instruments, but the latest and greatest ones involve lasers. This directs a highly focused and low power 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 well as the mass imbalance is indicated. If you think this is all too complex, let me tell you this is not rocket science. It’s more than likely that you already know about all this from personal experience. Know how you had to watch the mechanic line up and true your wheel balance? Remember that carefully calibrated additions had to be made at predetermined locations? Now, you that’s it in a nutshell. The nature and complexity of the laser vibration analysis and also the hardware hinges on the specific task at hand. And just who’s to say one way or the other, whatever it’s all about in the final analysis, anyway?
