ONLINE RESOURCES
Matlab Programs Used in Rao 4th Edition
The complete set of Matlab programs used in the textbook (Rao 4th Edition). This is a ZIP file that needs to be uncompressed into a single directory. Some of the programs are necessary or useful for solving homework problems.
Engineering Vibration Toolbox for Matlab (Wright State University)
A set of about 35 educational programs written in Matlab by by Prof. Joseph C. Slater. The programs can be run on any platform supported by MATLAB (Mac, Windows, VMS, Unix). Also included are help files, examples, and files containing raw experimental data. The codes include single degree of freedom response, response spectrum, finite elements, numerical integration, modal analysis and phase plane analysis. The files can be downloaded for free by students.
Online Vibration and Wave Book
A book on vibrations and waves in PDF available for free to students. This is more a physics rather than an engineering text that emphasizes waves and strings. However the basic ideas may be useful to engineering students in vibrations courses.
Wave and Vibration Portal
A site with links to very interesting pages on various wave and vibration phenomena. Make sure to visit the Tacoma Narrows Bridge Disaster site which contains clips of a movie showing the failure of a bridge under vibration-induced loads.
A list of links to various tutorial and animation sites related to vibrations and waves.
Acoustics and Vibrations of a Baseball Bat (Kettering University)
Very nice and interesting vibrations analyses of a baseball bat with animations of its modes by Prof. Daniel A. Russell.
The Tacoma Narrows Bridge Failure
A frame-by-frame analysis of the Tacoma Narrows bridge failure in 1940. Also includes link to video clip depicting a real-life failure of a large structure due to large vibrations.
A useful set of notes for practical measurements of vibrations in machinery and structures. Application Note 243 discusses various test protocols and the fundamentals of signal analysis. Application Note 243-1 describes the vibration characteristics resulting from common faults in machinery and methods of detecting and documenting them. Application Note 243-3 discusses the fundamentals of modal testing, frequency domain measurements, and modal parameter estimation.
