Features: The author has nearly 30 years of professional research and teaching experience. The main content of this book reflects the recent progress in the teaching reform of the Engineering Vibration Test and Analysis course at Tsinghua University. The book emphasizes the explanation of physical concepts, highlighting the importance of experimental theory, experimental measurement, and analysis techniques. It is meticulously arranged in terms of the connection between basic knowledge and modern technology, systematicity, completeness, and practicality, as well as necessary mathematical derivations and physical concepts. The book dedicates a significant portion to introducing the crucial similarity theory in structural dynamics experiments and provides engineering application examples. While retaining classic vibration measurement content, it adds the principles and methods of strain modal analysis and introduces several modern vibration measurement methods and equipment. In addition to classic signal analysis content, a dedicated chapter on signal conditioning and signal acquisition is included to help readers systematically and deeply understand the principles of experimental testing and specific engineering techniques. The book systematically introduces the theory and measurement techniques of vibration test analysis for machinery and engineering structures. The entire book consists of 12 chapters. Chapters 1 to 5 elaborate on the basic concepts of vibration measurement, signal conditioning, data acquisition, sensor technology, and conventional measurement methods. Chapters 6 and 7 introduce the fundamental theories of vibration signal processing and analysis, the basic concepts of random vibration, and signal analysis, including a comparison of Laplace transform and z-transform, as well as the random decrement method. Chapters 8 and 9 focus on the physical concepts of frequency response analysis and modal analysis, as well as basic modal analysis methods, with a special introduction to strain modal theory. Chapters 10 and 11 primarily explain the theory and methods of vibration and shock isolation, mechanical fault signal analysis, and operational monitoring. Chapter 12 introduces the model theory of structural vibration experiments and provides a special introduction to the similarity theory of model modal analysis. The book progresses from simple to complex, emphasizing basic concepts and experimental techniques, and systematically introduces modern vibration experiment and analysis techniques. All figures and formulas introduced are carefully considered for engineering applicability. This book can serve as a textbook or reference for senior undergraduate and graduate students in fields such as mechanics, aerospace, mechanical engineering, precision instruments, automotive engineering, power engineering, civil engineering, and engineering physics. It can also be used as a learning and reference material for a broad range of researchers and engineering professionals engaged in related research and applications.
