【Abstract】 Based on the theory of rotary mechanical vibration, the mathematic model of the laser phototypesetter vibration provoking by rotor unbalance was established, and the theoretical analysis matches the experimental results on the whole. The results shows that the vibration caused by the unbalanced rotor can be weakened by enhancing the base support rigidity, and the vibratory peak appears when the working frequency of rotor approaches the natural frequency of the laser phototypesetter system and supporting base, moreover the vibration and the request of base support rigidity can be weakened effectively by balancing the unbalanced rotor.更多还原
