Machine dynamics

Machine dynamics is a research area and subject that is based on the fundamentals of technical mechanics and deals with the interaction between dynamic forces and movement quantities within machines.

Neighboring areas with which there is overlap are

• the drive technology
• the driving dynamics
• the structural dynamics
• the measurement technology
• the vibration technology
• the mechatronics .

Mediated

• the experimental determination of dynamic quantities
• the vibration analysis
• Methods of modeling
• analytical and numerical methods as the basis for dynamic simulation and optimization .

The machine dynamics provide the basics

• for dimensioning the machine elements and assemblies ( vibration resistance )
• the balancing of rotors
• for calculating dynamic loads and deformations as well as critical speeds at which there is a risk of resonance .

The essential tasks of machine dynamics include

• the increase in working speeds
• the vibration isolation
• the reduction of vibration loads and noise
• the clarification of the causes of disturbing vibrations
• Measures to avoid damage .

Constructive tasks have to be solved

• when using
  • Vibration and shock absorbers
  • Vibration absorbers
  • Controllers
• in the development of machines based on dynamic operating principles , e.g. B.
  • Vibrating machines
  • Impact drills
  • Vibrating hammers
  • Vibratory conveyor
  • Vibrating mills
  • Swing tables
  • Centrifuges .
