Modal excitation sources impart vibrations into a system for modal analysis. The system is stimulated or vibrated by the excitation source and then external accelerometers measure the resulting vibration signature. Modal analysis is the process of breaking complex structural motion into individual vibration modes. Usually a Fast Fournier Transform (FFT) computer program is used to shift data from the time domain to the frequency domain. Once the data is in the frequency domain analysis, analysis can breaks complex vibration signature down to component frequencies and relate the modes to specific features in the systems. A piano wire coupler may be used to transmit the vibration to the test sample. Products & Services
Shakers and shock and vibration testing equipment are force generators or transducers that provide a vibration, shock or modal excitation source for testing and analysis.
Vibration analysis systems are used for vibration testing and modal analysis, including the instrumentation to acquire data and/or analyze results.
Engineering analysis and modeling software is designed to model, analyze, and predict responses and interactions for applications such as materials, structures, chemical and biological processes, electronic system performance, etc.
Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample.
Predictive maintenance (PdM) and condition monitoring systems are used to predict equipment maintenance, and to monitor corrosion, oil condition, bearing wear, overheating and other parameters than can lead to the breakdown of capital equipment.
