| 摘 要： | 从梁的振动基本理论出发,寻求适合不同结构超声波电机的振动理论与振动方程,分析和计算了环形和柱体两类超声波电机的振动模态和固有频率,研究了剪切变形与转动惯量对超声波电机振动特性的影响.结果表明:估算大直径环形超声波电机的振动特性可采用伯努利欧拉梁理论;计算柱体超声波电机的振动特性时,必须考虑剪切变形和转动惯量的影响,即应采用铁木辛柯梁理论. |
| 关 键 词： | 超声波电机 振动特性 剪切变形 转动惯量 固有频率 |

| Abstract: | The basic vibration theories of beams are recommended and applied to analysis and calculation of vibration mode and natural frequency of both ring-type and cylindrical-type ultrasonic motor.The effect of shear deformation and rotatory inertia to the vibration characteristics of ultrasonic motor is investigated.The results show that Bernoulli-Euler beam theory can be used to estimate the vibration characteristic of large diameter ring-type ultrasonic motor,however,to calculate the vibration characteristic of cylindrical-type ultrasonic motor,Timoshenko beam theory must be applied because the effect of shear deformation and rotatory inertia need to be considered. |
| Keywords: | ultrasonic motor vibration characteristics shear deformation rotatory inertia natural frequency |
