The student will be able to carry out problem oriented and technical resource oriented modeling of dynamical systems in order to investigate dynamical problems in real machines. This includes analytical and/or numerical solutions of the corresponding equations of motion. Measured pheomena in real machines can be compared with numerical simulation results from the mathematical models.
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.
