One, WDW-200 / 200KN / 20 吨 computer-controlled electronic universal testing machine main purposes of this subsection computer-controlled electronic universal testing machine can perform mechanical testing and analysis of the performance of metals, non-metallic and composite materials, widely used in aerospace, petroleum chemical industry, machinery manufacturing, plastics, rubber, ceramic materials, metal materials, construction and other industries, as well as universities, research institutions, technical supervision, inspection stations and other departments. Can be drawn according to GB / ISO / ASTM / JIS / DIN standards, compression, bending, shear, and a variety of high and low temperature test can detect the material yield strength, tensile strength (pressure, bending) strength, elongation, non- proportion of strength, elastic modulus and other parameters. Two, WDW-200 / 200KN / 20 吨 computer-controlled electronic universal testing machine host structure which electronic universal testing machine with double floor-space structure, the space stretching space under compression, bending. Host part consists of four columns, on the beam, the beam, floor-to-table composition framework, speed control system installed in the lower part of the table, by the speed and high precision, wide range, stable performance of Panasonic AC servo motor by synchronizing toothed belt deceleration system driven ball screw rotates, the ball screw drive beam, driving accompanied by stretching (or compression, bending accompanied) moves up and down to achieve the loading and unloading of the specimen. This structure has a high stiffness, high efficiency, driving stability. Host main components in the processing center for processing, to ensure the accuracy of the host.
