In order to improve the online detection precision and the reliability of high speed piezoelectric shape measuring roll,a set of industrialized integrated test platform of high speed Piezoelectric Shape Measuring Roll ("ICP-ITS" for short) was developed to analyze the effect of tension distribution,velocity schedule,load character and other factors on the shape detection signal.For ensuring the accuracy of flatness detection signal,the accurate dynamic calibration and the error measurement were first realized in the platform.On this basis,the platform adopts the strip driving structure and the axially moving press wheel mechanism to simulate the shape of the industrial rolling sheet,which can achieve the simulation of different wave shape and the detection of the shape of the plate.The experimental results indicate that the platform can improve the detection precision,shorten the calibration cycle and have an important practical significance to promote industrial application of the shape meter.
