Analysis of vibration causes
Vibratory phenomena observed in industrial plants generally result from complex interactions between mechanical, acoustic and dynamic excitations of structures. If left unchecked, they can lead to vibration amplification, excessive noise levels, premature component fatigue or critical mechanical failure.
Vibration cause analysis aims to identify the precise origin of these phenomena, in order to objectify the mechanisms involved and guide effective, sustainable corrective action.
Role of cause analysis and scope of intervention
Analysis of causes is a key step in dealing with complex vibration problems. Its aim is to go beyond the simple observation of vibration levels to understand the physical mechanisms responsible for the disorders observed.
SIM Engineering supports manufacturers in a structured approach combining field measurements and advanced simulations, in order to identify the origin of vibrations, characterize mechanical interactions and methodically rule out potential causes.
Technical and industrial challenges
Analyses of vibration causes can be applied to many industrial contexts: piping networks, rotating machines, compressors, pumps, fans, support structures, process skids or energy installations.
Poorly identified vibration causes can lead to ineffective corrective action, repeated stoppages, high maintenance costs or increased risks to safety and regulatory compliance. Controlling the causes is therefore a major challenge for reliability and industrial performance.
Methodology and resources
SIM Engineering’s cause analysis studies are based on a global approach integrating experimental measurements and numerical simulation tools.
Field investigations are carried out using measurement resources tailored to the phenomena under study: vibration measurements, pulsation measurements, acoustic measurements and experimental modal analysis (EMA) or operational distortion analysis (ODS). These campaigns are carried out on site, in operation or at standstill, depending on the objectives of the study.
In addition, advanced simulations are used to reproduce observed behavior and analyze underlying mechanisms: pulsating simulations (NEART), mechanical simulations of pipe networks (Autopipe), finite element modeling (Ansys) and AIV/FIV coincidence studies. This combination makes it possible to cross-reference approaches and improve diagnostic reliability.

Analysis and interpretation of results
Data from measurements and simulations are used jointly to identify dominant frequencies, excited modes and vibratory transmission paths.
Analysis enables us to distinguish the respective contributions of mechanical, acoustic or pulsatory excitations, identify resonance or coincidence phenomena, and understand interactions between equipment, structures and networks. The results are systematically compared with actual operating conditions to ensure a faithful interpretation of industrial operation.
Results and recommendations
Based on the causes identified, SIM Engineering defines targeted, prioritized technical recommendations. These may include design modifications, stiffness or mass adjustments, damping solutions, adaptations to operating conditions or optimization of piping networks.
The aim is to sustainably reduce vibration and noise levels, limit mechanical stress and prevent the recurrence of disorders.Expertise for industrial reliability
Analyzing the causes of vibration is an essential lever for ensuring the safety and durability of industrial facilities. By combining field measurements, numerical simulations and expertise in vibration engineering, SIM Engineering provides a detailed understanding of the phenomena and solutions adapted to industrial constraints.
This approach makes equipment more reliable, optimizes plant performance and makes vibration management part of a sustainable, controlled industrial approach.
