工作中发现,按Camp公式设计的磁致伸缩换能器,有载或空载时的工作频率低于设计频率.对Camp公式进行实验修正后,可以使换能器的工作频率基本等于设计频率,从而简化了声学振动系统的设计程序,保证换能器处于良好工作状态. Work found that, according to Camp formula design magnetostrictive transducer, with or without load at lower than the design frequency of the working frequency of the Camp formula for experimental correction, you can make the transducer operating frequency is substantially equal to the design frequency , Thus simplifying the design process of the acoustic vibration system to ensure that the transducer is in good working condition.
