Definition

Dynamics is the field of mechanics that deals with the connection between the motion of bodies and the forces acting on them.

Machine tool dynamics is based on Newtonian dynamics.

The Newtonian dynamics deals with macroscopic objects moving with a velocity negligible compared to the speed of light. Although Newtonian ideas have been overthrown by relativity and quantum mechanics, it is still the basic theory for engineering applications.

Theory and Application

Dynamics can be classified as follows:
  1. 1.

    Multibody dynamics that deals with large motions of rigid bodies

     
  2. 2.

    Vibrations that deal with small motions of deformable bodies

     
In machine tool dynamics, the following phenomena belong here:
  • Rigid body motions
    • Mechanisms

  • Vibrations
    • Free vibrations

    • Forced vibrations

    • Self-excited vibrations

    • Parametrically excited vibrations

Dynamic analysis is often associated with the term “stability.” Stability properties of dynamical systems are often...
