基于太赫兹技术的轮胎用覆胶钢丝帘布厚度检测

建立了基于太赫兹技术时域的轮胎用覆胶钢丝帘布厚度检测方法。对覆胶钢丝帘布的厚度进行静态检测，得到样品不同层面反射波强度信息；通过对反射波波动出现的时间进行分析计算，得到覆胶钢丝帘布的厚度及覆胶厚度。试验结果表明，利用太赫兹技术可以对覆胶钢丝帘布的厚度进行检测，其准确度和稳定性达到测定要求。;A detection method of the thickness of coated steel cord for tire based on terahertz technology time domain was established.The static thickness test for coated steel cord was carried out to obtain the intensity information of sample different levels.The thickness of the coated steel cord and coating thickness were obtained by analyzing and calculating the time of reflection wave motion.The test results showed that the thickness of the coated steel cord could be detected by the terahertz technology，and the accuracy and stability met the measurement requirements
