ANALYSIS OF TEST EQUIPMENT FOR INVESTIGATION OF MATERIALS UNDER A STRONG LOAD APPLICATION

Abstract

An analysis of modern testing equipment to establish the mechanical properties of different in structure and origin of building materials. As a result, it was established, that the most effective for testing are foreign electromechanical and servo-hydraulic machines of different configurations. It is determined that this type of technical systems allows to study different types of materials, including high-strength, compressive, tensile, bending and other types of loads in accordance with current international regulations. The article analyzes the principles of operation of the universal test machine INSTRON and the universal servo test machine UIT STM 100S. The configuration of such modern technical systems involves the availability of electronic computers and software, which allows testing in automatic mode, program research factors, determine the current and maximum values of mechanical properties of building materials, perform mathematical calculation of characteristics, reproduce information on the device screen, build research diagrams in electronic and printed form. It has been found that the advantages of such test machines are a load of up to 60 tons. It was determined that the universal machine UIT STM 100S is characterized by a large traverse stroke and a wide range of test speeds, which allows to expand the solution of quality control problems in industry. It is also established that the UIT STM 100S has software that includes a standard library of test methods according to regulatory documentation. The advantages of such a machine are the possible expansion of the standard information base necessary for the operation of the standards or the installation of an additional software module that provides the ability into independently supplement the standard library. Given the wide range of measurements of the universal testing machine UIT STM 100S, we envisage its use for the study of deciduous and coniferous wood in modern rigid test mode.
