Cheat Sheet
- Understand the fundamental principles of vibration - Vibration analysis starts with grasping how vibratory motion works, including how many ways a component can move (degrees of freedom). You'll explore the tag-team of displacement, velocity, and acceleration that drives every machine's rhythm.
- Identify common machinery faults - Every wobble tells a story: unbalance, misalignment, bearing defects or loose parts all have unique vibration fingerprints. Learn to decode these signatures so you can find and fix issues before they become dramatic breakdowns.
- Master Fast Fourier Transform (FFT) - Transform time-domain data into the frequency domain to spot the exact "notes" machines hum at when healthy or hurting. FFT is like a musical score for vibrations, revealing the secret frequencies of each fault.
- Select and apply vibration sensors - Choosing between accelerometers, velocity sensors, or displacement probes is like picking the right tool for a recipe. We'll show you when and why each sensor shines so your measurements hit the mark.
- Develop time waveform analysis skills - Time waveforms capture transient events and machine behavior under real-world conditions, giving you the full story. Become adept at spotting spikes, impacts, or anomalies before they escalate.
- Explore signal processing techniques - Cut through noise with windowing functions like the Hanning window to minimize spectral leakage and sharpen your frequency peaks. These tricks make your analysis cleaner, clearer, and more reliable.
- Leverage phase analysis - By comparing vibration phases, you can pinpoint relative motion and catch misalignment or unbalance. Think of phase data as the choreography guide that aligns every dancer in the machine.
- Learn balancing procedures - Master single-plane and multi-plane balancing methods to smooth out rotations and extend equipment life. Perfect balance keeps vibrations low and morale high.
- Get certified with ISO 18436 - Familiarize yourself with the global standards for vibration analysis to boost your credibility and ensure industry best practices. Certification is your passport to top-tier maintenance roles.
- Practice interpreting vibration data - Hone your skills by diagnosing spectra and time-domain plots, then craft clear, actionable reports. Strong communication of your findings can be as vital as technical expertise.
