摘要
介绍一种基于声循环多次脉冲反射法的辊型在线测量系统,并给出了系统的误差补偿分析,本测量法克服了多次反射法中对回波脉冲个数的限制,测量精度得到了明显改善,试验表明测量标准差为7.69μm,在高精度滚型模型在线获取方面具有广阔的应用前景。
A novel measurement of roll profile is introduced, and the composition and the error compensation analysis of this system are present. The testing method of the system is based on the sonic circulation and multi-pulse echo technique which can conquer the limitation of pulse-echo times and improve the accuracy of measurement. Experiment indicates the standard deviation of measure data is 7.69μm. It seems that it will get well applications foreground in the field of roll profile measurement.
