Vibration Diagnostics

Vibration DiagnosticsVibration diagnostics are used to identify the root cause of noise and vibration problems in machinery. Techniques such as operating deflection shape (ODS) analysis, spectral analysis, order tracking, and joint time frequency (waterfall) analysis are used to detect abnormal vibration characteristics. These techniques are applicable to a broad range of vibration related problems such as fatigue failures, excessive noise, resonance, manufacturing process quality issues, structural vibration, abnormal wear, and floor vibration. Knowledge gained from these vibration diagnostic techniques leads to practical solutions such as specification of isolation systems, tuned mass dampers, surface damping treatments, shaft balance and alignment procedures, excitation source control, repair procedures, natural frequency detuning, and active vibration control. SimuTech performs machinery vibration diagnostics both in its laboratory and on-site at customer facilities.

Recent vibration diagnostics applications include failure investigation of a material separation machine, heavy equipment cab noise reduction, and floor vibration survey for sensitive equipment.

Expertise in advanced vibration measurement and analysis techniques including modal testing (rap testing or bump testing), operating deflection shape (ODS) analysis, strain gage measurements, spectrum (signature) analysis, order tracking, joint time frequency (waterfall) analysis, demodulation, and finite element analysis (FEA) and state of the art equipment enables SimuTech to diagnose the root cause of noise and vibration problems. Based on a clear understanding of the problem SimuTech provides practical solutions such as specification of isolation systems, tuned mass dampers, surface damping treatments, shaft balance and alignment procedures, excitation source control, repair procedures, natural frequency detuning, and active vibration control. SimuTech’s vibration troubleshooting and diagnostic service offers state-of-the-art techniques at reasonable prices with a strong commitment to customer service.
