In document one degree of freedom system and its behavior, equations and next modification as system of free vibration, harmonic excitation, structural damping is defined.
There are two main descriptions of motion: dynamics and kinematics. Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations. However, kinematics is simpler. It concerns only variables derived from the positions of objects … WebThe modal mass, associated with mode m, is calculated as \begin {equation} m_m = \vec {a}_m^\mathrm {T} \mat {M} \vec {a}_m \end {equation} where \vec {a}_m is the …
