摘要

通过对固体火箭发动机药柱材料黏弹性的分析决定了超声检测探头的最佳频率为1 MHz.采用双探头脉冲反射法

综合了穿透法和脉冲反射法的优点

实现了超声信号在固体火箭发动机药柱中传播时能量强衰减的情况下超声回波信号幅值的最优化.利用超声缺陷信号的时频域特征

较好地实现了该类型药柱的线性定量无损检测.

Abstract

The ultrasonic test probe with the frequency of 1MHz is optimal by analyzing viscoelastic property of material of solid rocket motor grain.The double-probe pulse echo method

combining the advantages of transmission technique and pulse reflection method

is used to optimize the ultrasonic echo signal amplitude in case of strong attenuation of energy when ultrasonic signal transmitting in solid rocket motor grain.The linear and quantitative nondestructive test of the grain defect is realized by using time-frequency domain character of the ultrasonic defect signal.
