| Abstract: | Vibration measurement of rotating blade is mainly non-contact.Nowadays,the hardware technology is growing mature and various arithmetics are now the focus study both home and abroad.Blades synchronization vibration arithmetic by blade-tip-timing was discussed.The vibration frequency and breadth of rotating blades on some fan sample were measured by this system.And the blade resonance at 6 700 r/min was analyzed.Compared with measurement results and theoretical calculation results,it showed conformity in vib... |
