Mechanical Engineering

To investigate the relationship between
the mass of the body, the stiffness of the spring and the periodic time
or frequency of the oscillation of a spring-mass system having one
degree of freedom.

• To investigate the effect of viscous damping on the free vibration of a simple spring-mass damper system.


• To investigate the relationship between
  the amplitude of the steady state vibration of the vibrating mass and
  the forcing frequency for varying damping ratios.

(a) 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.

(b) 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.

• To investigate the phase relationship
  between the vibrating mass and the periodic displacement of the spring
  support for varying damping ratios.

Technical specifications

• 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. Variable
  viscous damping is provided by an oil dashpot.


• 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.


• Two pen recorders are provided, a
  continuous paper recorder for amplitude and frequency measurements and a
  rotating drum recorder for amplitude and phase measurements.


• Experiment manual.
