Constant modal damping

A machine tool can be described using equation [1], where \(M\) is the mass matrix, \(D\) is the damping matrix and \(K\) is the stiffness matrix.

\[M \ddot{x} + D \dot{x} + K x = 0 \quad [1]\]

Using the constand modal damping model, the same modal damping coefficient is applied to every mode of the system.
