Produktbeschreibung

Mechanical Wave Vibrations An elegant and accessible exploration of the fundamentals of the analysis and control of vibration in structures from a wave standpoint In Mechanical Wave Vibrations: Analysis and Control, Professor Chunhui Mei delivers an expert discussion of the wave analysis approach (as opposed to the modal-based approach) to mechanical vibrations in structures. The book begins with deriving the equations of motion using the Newtonian approach based on various sign conventions before comprehensively covering the wave vibration analysis approach. It concludes by exploring passive and active feedback control of mechanical vibration waves in structures. The author discusses vibration analysis and control strategies from a wave standpoint and examines the applications of the presented wave vibration techniques to structures of various complexity. Readers will find in the book: * A thorough introduction to mechanical wave vibration analysis, including the governing equations of various types of vibrations * Comprehensive explorations of waves in simple rods and beams, including advanced vibration theories * Practical discussions of coupled waves in composite and curved beams * Extensive coverage of wave mode conversions in built-up planar and spatial frames and networks * Complete treatments of passive and active feedback wave vibration control * MATLAB¯® scripts both in the book and in a companion solutions manual for instructors Mechanical Wave Vibrations: Analysis and Control is written as a textbook for both under-graduate and graduate students studying mechanical, aerospace, automotive, and civil engineering. It will also benefit researchers and educators working in the areas of vibrations and waves.
