摘 要: 介绍以小信号正弦电磁激振和脉冲敲击激振,加速度计进行信号检测的扭振超声变幅杆谐振频率和角位移放大系数的测定方法。该法已应用于科研试验中。 Methods for measuring the resonat frequency and the angle amplification ratio of torsional transformers are introduced in which a small-signal sine electromagnetic excitation or an impulsive mechanical knock excitation is used to excite the horn and accleromoters are used to measure the response signals. The methods have used in experimental studies.
