摘要
介绍了一种超声导波激励信号发生器的设计方法,选择扭转模态的超声导波为发生对象,通过导波分析确定设计的导波频率,并根据所需信号的特点进行设计.采用ATmega32,AD9851和DAC0832进行硬件设计并调试系统.仿真及结果表明此方法可行.
A method of ultrasonic guided-wave signal generator design is introduced. A torsion modal is choosed and designed in accordance with the characteristics of the desired signal and using ATmega32, AD9851 and DAC0832 to design signal generator. Simulation results show that this method is feasible.
