Free And Forced Vibrations

•    This gives a simple and quick system set up and changeover time.
•    This gives minimal cyclical variation due to inertial load variations.
•    A non-contacting sensor measures beam displacement.
•    Students may vibrate the systems manually.
•    The servomotor has its own encoder and advanced controller for accurate speed regulation.
•    The sensor has no physical contact with the oscillating system, for negligable damping.
•    This ensures repeatable results over a range of ambient temperatures.
•    An encoder linked to the rotating exciter mass measures its dynamic position.
•    They may also force the vibrations using a high-quality variable speed servomotor driving a rotating offset mass - forming an ‘exciter’.  
•    The beam is of high-grade ground steel, and the pivots use high-quality ball races for lowest friction and incidental damping.
•    An accelerometer built into the exciter assembly works to show the phase relationship between beam displacement and acceleration.
•    It also helps to compare measured acceleration with that derived from the displacement using the software.
•    The unit includes a variable-area viscous dashpot damper, for use with a non-toxic fluid (supplied) of stable viscosity.
