Piping Systems susceptible to vibration: AIV / FIV

García-Lozano, Javier Different excitation mechanisms can cause piping vibration; the induced fatigue could have catastrophic consequences and finally lead to the failure of the system. In addition to some sources of vibration historically considered (reciprocating pumps and compressors, 2 phase flow…), nowadays is becoming more demanded the study of the AIV (Acoustically Induced Vibration) and…

Modal Analysis for the Plant Machinery Engineer. Recipes and Shortcuts. Part II

Vázquez, José Antonio Experimental modal analysis and operating deflection shapes (ODS) are powerful tools in vibration analysis and machinery troubleshooting. However, the plant machinery engineer often doesn’t believe such techniques are available given a lack of advanced measurement equipment. This tutorial presents best practices with simplified experimental modal analysis and ODS techniques that can be…
