A Modal Vibration Shaker, also known as a Modal Shaker, is a specialised type of vibration testing system designed for performing modal analysis on structures and components. Modal analysis is a technique used to study an object’s natural frequencies, mode shapes, and damping characteristics. Modal shakers are equipped with the capability to excite the structure or component under test at specific frequencies and record its responses, allowing engineers and researchers to determine its dynamic behaviour. Modal shakers are attached to the structure with a stinger, and the force is transferred from the shaker to the structure via this stinger.
