METHOD AND APPARATUS FOR MEASURING DAMPING IN A WORKPIECE |
| 摘要 |
A method and apparatus for measuring damping of a work piece are provided. The method includes determining at least one suitable location to measure damping on the work piece, exciting the work piece at the at least one suitable location, measuring a dynamic response of the work piece at the suitable location, and calculating a damping factor and a Q factor from the dynamic response. The apparatus includes a response measurement device configured to obtain response data, such as displacement data and/or velocity data, used in determining the at least one suitable location to measure damping. |
