Free & Forced Vibration Apparatus
Vibrations induced by a periodic displacement of the point of support of the spring. In this experiment a connecting rod, driven by an eccentric, imparts a such that on revolution of the eccentric is equal to one revolution of the phase recorder.Vibrations induced by applying a periodic disturbing force to the mass. In this experiment the exciter unit is driven from a gearbox via a flexible coupling such that one revolution of the contra rotating discs is equal to one revolution of the phase recorder. Vibrations induced by applying a periodic disturbing force to the mass.
Technical specifications:-
• Two methods of exciting forced vibration are adopted; either by oscillating the upper spring mounting with SHM at variable frequency or by applying a rotating out balance force at variable frequency to the vibrating mass.
• The use of so called “Black Boxes” has been avoided, a feature welcomed by most teachers.
• Simple adjustments can be made to the apparatus and the motion of the mass can be readily observed and recorded on the two pen recorders provided.
• Adopting the well tried features of the simple Vibration Apparatus, the mass carriage is constrained by rollers on vertical guide ways to provide minimum uncontrolled damping.
• Two pen recorders are provided, a continuous paper recorder for amplitude and frequency measurements and a rotating drum recorder for amplitude and phase measurements.
• Variable viscous damping is provided by an oil dashpot.
• Experiment manual.
