A summary of different structural dynamics analyses we carry out is offered listed below:.
- - Frequency Reaction Analysis - A type of forced-response analysis where the excitation is harmonic (single frequency) and the structure reacts linearly. - Shock Reaction Analysis - A type of forced-response analysis where the excitation is defined in the kind of a shock spectrum. Strategies like functional modal analysis (OMA) and running deflection shapes analysis (ODS) work while the structure is in operation, permitting you to get a sensible photo without having to synthetically thrill the structure..
.Frequency Reaction Analysis.
- - Frequency Action Analysis - A kind of forced-response analysis where the excitation is harmonic (single frequency) and the structure reacts linearly. This analysis is utilized to identify the steady-state action at any place to harmonic excitation. Helpful for examining the structural reaction to vortex shedding (wind-induced excitation), mechanical system excitation (e.g., a pump), and supplies insight into worst-case reaction to pedestrian-induced vibration..
- - Modal Analysis - Supplies the mode shapes and matching resonance frequencies for the structure and is utilized in the forced-response analyses..
- - Random Vibration Analysis - A type of forced-response analysis where the excitation is identified through a power spectrum and the structural action is direct. This analysis is utilized to examine the action brought on by unstable air/fluid-induced vibration and ground-borne vibration..
- - Shock Reaction Analysis - A kind of forced-response analysis where the excitation is defined in the kind of a shock spectrum. This analysis mostly is utilized to evaluate structural reaction to earthquakes..
