Through a level one vibration analysis training course, students learn to read vibration signatures and evaluate machinery conditions from this data. Vibration analysis training prepares students to isolate a problem machine part and make recommendations for scheduled repairs or continued operation. Training usually lasts two to three days, according to Technical Associates of Charlotte in North Carolina.
Professionals who benefit most from vibration analysis level 1 training include plant personnel who need a basic understanding of analytical methodologies to help improve predictive maintenance programs. These professionals include maintenance supervisors, predictive maintenance coordinators, rotating machinery engineers, reliability engineers and advanced mechanics/technicians.
In level 1 vibration analysis training, students learn about waveforms, spectral analysis, phase measurements and amplitude measurement methods that help diagnose machinery conditions. Students also learn the strengths and weaknesses of various methods and learn what the typical machinery malfunctions actually are. The course additionally covers the best detection tools for each machinery issue and points to the warning signs of problems.
The level 1 course covers the scientific topics of displacement, velocity and acceleration and teaches students how to convert these measurements. This course also includes discussion of analog and digital methods, the role of high frequency detection and problems such as mass unbalance, eccentric rotors, bent shafts and misalignment.
Students also learn about the problems of mechanical looseness, improper component fits, belt drive problems, gear-wear problems, soft feet and electrical problems within induction motors. Such problems are part of the field's well-known "Illustrated Vibration Diagnostics Chart." Students learn how to set up overall vibration alarms and optimum frequency ranges for a variety of machinery as well.
The first level of vibration analysis training further covers typical mistakes professionals make when making vibration measurements. These include incorrect sensor selection, improper measurement locations, incorrect measurement parameters, incorrect frequency spans and poor measurement techniques. Coupled with this is an introduction to successful predictive maintenance programs, which teaches students how prosperous programs were set up and the advantages they offer. Students can learn real-world case histories that explain how other professionals uncovered machine problems.
To be successful in a level 1 vibration analysis training course, students should be generally familiar with a calculator and computer. Also, an individual with at least six months of vibration spectrum analysis experience usually is more successful if he is interested in vibration specialist certification, and some programs require this experience to participate in the training program. Students also should possess good algebra skills. Other programs require students to be familiar with basic sensor and monitoring instruments.
