Electromechanical Motion Technology

The lecture 'Electromechanical Motion Technology' deals with the kinematics and kinetostatics of plane mechanisms with examples from many areas in the field of mechanical engineering. In particular crank and cam mechanisms as well as their hybrids will be introduced. One focus is the analysis and synthesis of nonuniform transmitting crank mechanisms.

Lectures and exercises are offered only in German language.
