The operational vibration analysis determines the vibration behavior of an object in a specific operating state. In contrast to the modal analysis, there is no artificial vibration excitation e.g. with the help of a shaker. Typically, operation excitation is limited to certain frequency bands.
An Optomet scanning vibrometer can measure the operational mode of vibration of an object and animate them by taking a large number of measurements at different points during operation. The combination of high spatial, amplitude and frequency resolution enables the developer or user to understand the behavior of the machine or system in detail and to optimize it in a targeted and efficient manner.
The investigation of such operating vibrations is used both for product development and for condition monitoring of plants and machines.
