METHOD OF MEASURING DAMPING USING OPTICAL IMAGING TECHNIQUE

摘要

A method of measuring damping of a work piece is provided. The method includes exciting the work piece, measuring a dynamic response of the work piece with an optical imaging system and calculating a damping factor and a Q factor from said dynamic response. The method links two processes: an optical imaging system to out put dynamic motion response data, and using the data to obtain a damping factor and a Q factor.
