Fundamentals of Mechanical Vibrations

Fundamentals of Mechanical Vibrations

This introductory book covers the most fundamental aspects of linear vibration analysis for mechanical engineering students and engineers. Consisting of five major topics, each has its own chapter and is aligned with five major objectives of the book. It starts from a concise, rigorous, and yet accessible introduction to Lagrangian dynamics as a tool for obtaining the governing equation(s) for a system, the starting point of vibration analysis. The second topic introduces mathematical tools for vibration analyses for single degree-of-freedom systems. In the process, every example includes a section Exploring the Solution with MATLAB. This is intended to develop student's affinity to symbolic calculations and to encourage curiosity-driven explorations. The third topic introduces the lumped-parameter modeling to convert simple engineering structures into models of equivalent masses and springs. The fourth topic introduces mathematical tools for general multiple degrees of freedom systems, with many examples suitable for hand calculation, and a few computer-aided examples that bridges the lumped-parameter models and continuous systems. The last topic introduces the finite element method as a jumping point for students to understand the theory and the use of commercial software for vibration analysis of real-world structures.

• Thorough and clear explanation of the fundamental concepts and theories without straying into more advanced topics
• Rigorous and yet accessible treatment of Lagrangian dynamics to arrive at the starting point of vibration analysis with confidence
• Expanding the horizon by exploring the capabilities of MATLAB for examples of many degrees of freedom and even complete finite element code
• Instilling the philosophy that, as an engineer, having a solution means the beginning of an exploration
