Abstract
The invention discloses a two-dimensional laser continuous scanning vibration measurement method for the high-precision full-plane modality under thermal operating condition, belonging to the technical field of high temperature modal testing. The invention comprises the following steps: quartz lamp arrays heat the free suspension plate; the excitation rod hits the free suspension plate to make it forced to vibrate; the laser vibrometer continuously scans the free suspension plate. The invention adopts the two-dimensional laser continuous scanning vibration measurement method for the high-precision full-plane modality under thermal operating condition, which improves the precision of the high temperature modal vibration mode by 20 times.
