An automatic device based on flexivity precise measurement technique

When temperature change, the flexivity will be changed for various components level's thermal-expansion coefficient is different for sheet of Metal Composite. The performance of sheet of metal composite is affected enormously and the change quantity is a micron level. Based on the pattern displacement sensor, according to related national examination standard, the automatic precise measurement device of sheet of metal composite is designed. The testing is realized automatically, because that the data is transmitted through the RS-232 connection, then analyzed and the report is resulted after this. The test result indicated that the flexivity accuracy amounts to 4 microns, The efficiency, precision and technology of the device have been rapidly improved. © 2010 IEEE.
