Operating Deflection Shape Analysis
Operating deflection shape analysis creates a visual portrayal of the movements of structures and machinery caused by vibrations during normal operation.
Operational Deflection Shape Analysis
Why is ODS analysis important?
Operational Deflection Shape, or ODS, analysis shows how complex structures and machines actually move while operating.
By measuring vibration during normal running and displaying the movement as an exaggerated animation, ODS makes it easier to see shape, phase and direction of motion. This helps identify problem areas and supports practical decisions around supports, clearances, stiffness and corrective action.
ODS helps you:
Gain real-world insight
Visualise shape, phase and direction of motion under operating conditions.
Improve diagnosis
Identify looseness, soft foot, resonance interaction and boundary condition issues.
Target better fixes
Focus corrective actions on changes that reduce movement and risk.

How AVT Can Help
ODS analysis that turns complex movement into practical action
Complex systems often exhibit multiple mode shapes and frequencies that can be difficult to interpret from data alone. AVT Reliability engineers use ODS to visualise and animate vibration during normal operation.
Results can be presented per single frequency, known as frequency-based ODS, or across time, known as time-based ODS. With extensive field experience, our engineers translate animations into practical corrective actions.

ODS Process
How does ODS analysis work?
ODS uses measured operating vibration, a geometric model and animation to show how an asset is moving under real running conditions.
Measure operating response
Capture vibration at key locations during normal running using suitable sensors and data acquisition.
Build the model
Map measured points to a geometric model of the asset to represent movement accurately.
Animate and interpret
Generate frequency-based or time-based animations, interpret motion patterns and recommend corrective action.

Key Applications
Where ODS analysis can support reliability
ODS is particularly useful when vibration problems are distributed across structures, frames, mounts or piping systems and the movement pattern needs to be understood clearly.
Motor and pump mounts
Determine how vibration issues affect motor and pump mounts, including movement patterns and support behaviour.
Compressor skids and frames
Carry out mode shape analysis of compressor skids, support frames and similar assemblies to understand operating movement.
Large piping systems
Investigate vibration problems across large piping systems where issues may appear at multiple locations.
ODS can be integrated into a wider asset management programme, helping maintenance and engineering teams make better decisions from measured operating data.
