【摘要】 本研究是在大量的实验数据的基础上,通过建立物理、数学模型,用计算机计算模拟弯曲型驱动器的振动模式,得到了驱动器受激时的振动状况,如各阶谐振频率和各阶谐振振型等.另外还给出了各阶谐振频率的拟合经验公式.最后,计算模拟并且分析了加轴驱动器振动模态,对加轴的可行性给予了评价.更多还原

【Abstract】 Based on a large amount of experimental data,the oscillation of bending piezoelectric ceramic antuator wassimulated by setting up the physical and mathematical model. The resonance frequencies and modes were calculatedby FEM. An experiential formula was given by fitting the experimental and calculated results. The effects of adding anaxis at the center of the mirror on the oscillations were analyzed. The results showed that the axis can reduce theoscillation of the actuators.更多还原
