A textbook for a senior or early graduate engineering course in vibration and servos and for practicing engineers. Hatch a mechanical engineer with a long background in disk drives, assumes a background in basic vibrational theory and elementary Laplace transforms, but little or none in state space. He collects in one volume various methods of constructing and representing dynamic mechanical models so help engineers distinguish and choose between the bewildering array. He also helps readers develop a strong understanding of modal analysis, and shows how to use the results of large dynamic finite element models to build small MATLAB state space dynamical mechanical models for use in mechanical or servo/mechanical system models.
