High precision measurement technology of small diameter pipe

  • 摘要: 建立了一套基于离散信号周期分离与统计的小管径管材外形尺寸测量方法,在不苛求机械安装精度的前提下,提高核级小管径管材外形尺寸的测量精度。并通过自研的TESC-200管材高速检测系统在4 000 r·min-1的条件下进行试验,验证了该方法的有效性。
    Abstract: When the outer diameter of the small diameter pipe is measured by the double ultrasonic probe immersed in water, the axis of the probe group cannot be completely coincident, and the imeasurable deviation of the rotation center of the probe group and the axis of the tube to be detected shall result in the error of the outside diameter being beyond the nuclear level of small diameter pipe measurement requirements. To this end, the discrete signal cycle separation and statistics of small pipe diameter measurement method were established, which shall improve the nuclear grade small diameter pipe diameter measurement accuracy without demanding mechanical installation accuracy. And the validity of the method was verified by the self-developed TESC-200 pipe high-speed detection system under the condition of 4 000 r·min-1.
