DEVELOPMENT AND DETERMINATION OF THE MAIN PERFORMANCE INDICATORS OF THE CALIBRATION PLATE BASED ON A COMBINATION OF CONCRETE AND GLASS

Abstract

The work considers a surface plate, designed and manufactured from glass and reinforced concrete as a working surface and the base of the plate, respectively. The results of researching of the main metrological and operational characteristics of the plate are presented, such as surface flatness and irregularity of the working surface, the greatest surface deflection under the action of a distributed load. It has been established that the developed experimental sample of the composite plate is suitable for accuracy class 000 in terms of surface irregularity, and for other characteristics, it does not even suit for accuracy class 3. In addition, the reasons are identified and further directions for improving the design and manufacturing method are established in order to improve the metrological and operational characteristics of the composite plate
