## Learning outcomes

After successful completion of the course, students are able to...

• analyze 2D-mechanisms  and teir properties
• use correctly terms as "applied forces", "constrain forces" and mass forces"
• calculate and minimize the degree of non-uniformity in drive systems
• analyze and understand vibrations of linear multi-degree of freedom systems
• solve complex problems in modelling of torsional vibration systems
• answer basic questions related to bending vibrations of rotating machines
• foresee the effects of mechanical vibrations on humans

## Subject of course

Introductory examples on modeling of machine dynamical systems. Geometrical and kinematical characteristics of planar mechanisms. Equations of motion and constrained forces of SDOF-mechanisms. Examples: circular cam drive, crank gear mechanism, drive train of a pump. Steady state speed variation of mechanisms, oscillating unbalance and inertial forces of crank drive machines, balancing of oscillation forces. Vibrations of linear MDOF-Systems. Extended modelling of torsional drive trains. Gear and belt drives with and without torsion to bending vibration coupling. Bending vibrations of shafts and rotors. Vibration effects to humans, buildings and machines.

## Teaching methods

Weekly lecture presenting slides and using a data projector. The presentation slides are based on the available script, but are extended, supplemented and presented graphically and visually according to didactic principles.

Written and oral

## Literature

Lecture notes for this course are available.

## Previous knowledge

Knowledge on the content on "vibrations" of the lecture Mess- und Schwingungstechnik is required! It is also advantageous having completed Mechanik 2, because the lecture is partly based on the contents of the lecture Mechanik 2.
