Machine dynamics
Machine dynamics refer to the study of a system’s motion based on the forces acting on the system. Machine dynamics apply knowledge of engineering mechanics, especially dynamics, to the problems of real machines.
Basic knowledge machine dynamics
- Vibrations in machines
- Rotor dynamics
- Balancing
- Mass forces and mass balance
- Vibration isolation
- Machinery diagnosis
Examination of different vibrations, e.g. torsional vibrations or natural vibrations on the example of a model.
Experimental equipment used to investigate vibrations in rotating components such as shafts.

In vibration insulation, we look at two cases: the transmission of periodic, shock-like or stochastic forces from a machine to surrounding structures or vibrations from the environment to the machine.

The aim of machinery diagnosis, also known as machinery status monitoring or condition monitoring system (CMS), is to conduct needs-based maintenance or repair and therefore to minimise the repair and downtimes of a machine.
