摘要
利用弹性动力学理论对半无限长弹性细长梁进行了分析 ,得出在弹性细长梁上激励出大振幅弯曲行波振动的条件 ,对以此为基础研制的直线超声行波马达的定子进行了振动特性分析 ,着重分析了行波反射对定子振动状态的影响 ,认为一般情况下定子上的振动是含有驻波场的行波 ,并对不同反射系数条件下的定子振动波形进行仿真 ,最后通过实验研究了驻波场对超声马达驱动特性的影响 .
Semi-infinite slender beams were analyzed with the theory of elastodynamics, and the conditions for large amplitude of slender beams were calculated. Based on the conditions, a linear traveling-wave Ultrasonic Motor (USM) was developed. Vibration of the stator of USM was analyzed based on the consideration of traveling-wave reflection. With the help of simulation, it was shown that the reflected wave exhibits a great influence on drive characteristics of USM. A series of experiments proved the validity of the conclusions.
