Summary
Extending knowledge about vibration of one degree-of-freedom linear systems,
vibrations excited by rotating mass, transfer of force to subsurface, forced
vibrations excited by periodic force and by force of general time behaviour.
Longitudinal and torsion vibration of linear multi degree-of-freedom systems,
bending vibration of linear multi degree-of-freedom systems, critical speed of
shafts. Non-linear one degree-of-freedom systems vibration.
Learning Outcomes of the Course Unit
To teach the students the basic theory of linear vibration with one and more degrees of freedom. To teach the basics of non-linear vibration of mechanical systems. To be able to apply the retrieved knowledge to solve the technical problems.
Course Contents
The natural longitudinal vibration, undamped and damped, linear, with 1 degree of freedom (DOF).
The spring assemblies, serial and parallel.
Bending stiffness, bending vibration.
The forced vibration, undamped and damped.
Constant force, harmonically changing force.
The steady state solution. The amplitude and phase diagram.
The vibration due to centrifugal force.
The force transmision into the ground.
Rotational vibration, natural and forced, torsional stiffness.
