INDUSTRY SOLUTION
Automotive Vibration and NVH Testing
Non-contact vibration, operating-deflection and modal testing for vehicle structures, powertrains, components and development benches.
Non-Contact Vibration and NVH Testing for Automotive R&D
Automotive components, body structures and bench tests frequently involve many measurement points, non-stationary conditions and complex boundaries. Laser vibrometry acquires surface response without attaching sensors and can support source localization, operating-deflection analysis, structural modal testing and iterative design validation.
Typical Measurement Tasks
01
Measure vibration response of body, chassis, interior or exterior trim and precision components.
02
Localize vibration sources, compare local anomalies and visualize ODS under operating conditions.
03
Compare experimental or operational modes with simulation by frequency and mode shape.
Recommended Products and Configuration Logic
Use the Gantry 3D Scanning Laser Vibrometer System for laboratory components and benches; the Multi-Channel Synchronous Laser Vibrometer where references or non-stationary response are important; and modal measurement and analysis to manage scanning, acquisition and interpretation.
Suggested Test Workflow
- Record fixture, preload, temperature and operating condition so comparison boundaries remain consistent.
- Select the laser line of sight and coordinate system, then plan reference channels.
- Review raw time histories, return signal and synchronization before frequency-domain or modal analysis.
- Interpret abnormal frequencies together with mode shapes, excitation and transfer paths rather than relying on one spectral peak.
