Vibration analysis is a multidisciplinary subject and presents a system dynamics methodology based on mathematical fundamentals and stresses physical system modeling. The classical methods of vibration analysis engineering are covered: matrix analysis, Laplace transforms and transfer functions. The numerous worked examples and unsolved exercise problems are intended to provide the reader with an awareness of the general applicability of vibration analysis problems using MATLAB. An extensive bibliography to guide the student to further sources of information on vibration analysis using MATLAB is provided at the end of the book. All end-of chapter problems are fully solved in the Solution Manual available only to Instructors.
