 INTRODUCTION

Plant maintenance is essential for safe operation and personal safety. Given its cost, however, it's a good idea to strike the right balance between systematic preventive and corrective maintenance.

Plant monitoring helps limit the need for preventive maintenance. In this context, vibration analysis is a tool for detecting and diagnosing plant malfunctions.

After describing the main vibratory manifestations of machine malfunctions, this article examines detection and monitoring strategies, and the diagnostic approach based on vibration analysis, which can be used to deduce maintenance policies and actions.

Readers are invited to consult the articles :

  • Vibration analysis of rotating machines [BM 5 145] in Génie mécanique ;

  • Vibrations [A 410] in the treatise Fundamental Sciences ;

  • Aeroacoustics and hydroacoustics [A 430] in the treatise Fundamental sciences ;

as well as articles in the Mechanical Functions and Components section of the Mechanical Engineering textbook.

Note :

vibrations are characterized by displacement, velocity or acceleration. In this article, we will schematically represent the phenomena regardless of the parameters measured (which depend on the type of sensors used in each case). The curves thus obtained are generally representative of the evolution of the amplitude of the vibration's displacement, velocity or acceleration.
