Modal Analysis

Scenic Acoustic specialise in the provision of Modal Analysis Services for the assessment of Structural Dynamics and Rotor Dynamics.

In conjunction with our partners, we can perform modal analysis on structures/components to ascertain vibration mode shapes and associated frequencies, using SIMO, MISO and MIMO approaches. Modal analysis enables our clients to reduce noise levels emitted by machinery and assists in the determination of damaging resonant frequencies that may result in fatigue failure of structures/components, if not damped correctly. The damaging effects of resonance is perfectly demonstrated in the Tacoma Narrows Bridge collapse in November 1940.
