Mechanical Engineering
Technical Specification
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. 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.
• 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.
• The use of so called “Black Boxes” has been avoided, a feature welcomed by most teachers.
• 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.
