Features: This book is recommended by the Graduate Education Office of the Ministry of Education as a teaching material for postgraduate studies. It is divided into two parts, covering 16 chapters. Part 1 systematically introduces the fundamental principles of structural and mechanical vibrations and their applications in engineering. The content mainly includes: single-degree-of-freedom systems, multi-degree-of-freedom systems, and free vibrations of elastic bodies; theories and methods of forced vibrations; vibration control theory, nonlinear vibration theory, and effective numerical calculation methods, such as the finite element method, used in engineering. Part 2 discusses the basic theories of engineering vibration testing technology and the practical applications of modern engineering testing technologies in engineering. The content mainly includes: the working principles and applications of vibration sensors, testing systems, excitation equipment, and laser vibration meters, as well as their calibration; measurement of basic vibration parameters; analog steady-state signal analysis; digital signal analysis; an introduction to experimental modal analysis; parameter identification; and engineering application examples. The book is rich in content, easy to understand, and progresses from simple to complex, with a practical focus. It can serve as a textbook or reference book for postgraduate students or undergraduate students in mechanical engineering or mechanics, as well as for engineering technicians engaged in mechanical, aerospace, aviation, shipbuilding, vehicle, construction, and water conservancy fields.
