Free And Forced Vibrations Manufacturer,Supplier and Exporter in India

• 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.
