摘要:

针对现在超声测厚出现的精度不够高、测量误差比较大、噪声的干扰问题,除了在硬件方面的改进,还利用相关算法,来提高测试的精度和减少噪声干扰问题;利用10 M测厚探头对30 mm带细微螺纹铁标准试块和1 mm的不锈钢试标准试块测量,验证了测量的有效性和准确性;该系统运行稳定,能够可靠地进行检测厚度,在超声测厚领域将会具有极高的应用价值。

Abstract:

Now the problems of ultrasonic thickness measurement include that precision is not high、measurement error is relatively large and the noise is relatively large.To solve these problems, cross-correlation algorithm can be used to improve the precision and reduce the noise jamming, in addition to improvements in hardware. Through the calculation of the thickness of The 30mm with fine thread iron standard test block and 1mm stainless steel test standard test block, the effectiveness and accuracy of the measurement is verified. The system runs steadily,detects thickness reliably and the application value is much higher in ultrasonic thickness measurement field . 
