Upgrading of “IMASh 20-78” unit with a computerized test management system and data processing

An electronic module of control and data acquisition and transmission “BUPSD 01” has been developed for the IMASh 20-78 test unit which can be used both as a stand-alone control device and in conjunction with a computer. The software has been developed that allows detecting of loads and deformations using sensors, setting the speed of the grasp movement, and carrying out photo and video shooting with simultaneous construction of test schedules. As a result of the deep modernization of the unit developed more than thirty years ago, an almost new testing machine equipped with modern electronics with a wide functionality was obtained. Three stationary control racks and module of video recorder-monitor playback system are replaced with data acquisition and transmission control module, WEB camera and personal computer. Combination of the reliable mechanics (reduction gears, electric motors, grippers), which is part of the original installation with modern electronic equipment and software, allowed using of the unit at a qualitatively new level of research. In a modernized form, the unit is capable of continuous recording of data on loading and deformation into a text file and plotting a process schedule using this information storing it in the file. The video system control the entire test process with a WEB camera mounted on a microscope and record it in a file with the possibility of subsequent playback. Moreover, the system can take photos at any time and save them on the computer. The device has been tested in the study of the samples of metal alloys with various galvanic coatings and polymer composite materials. Information about new characteristics of the studied materials became available now in addition to the mechanical characteristics obtained earlier.
