Microcomputer controlled electronic tensile testing machine

The gantry style microcomputer controlled electronic universal material testing machine complies with national standards such as GB/T228-2010 "Method for Tensile Testing of Materials at Room Temperature", GB/T7314 "Method for Compression Testing of Materials at Room Temperature", GB/T232 "Method for Bending Testing of Materials", etc. The computer system uses a fully digital controller to control the servo motor to rotate through a speed regulation system. After being decelerated by a reduction system, it drives the moving crossbeam to rise and fall through a precision ball screw pair, completing various mechanical performance tests such as tension, compression, bending, and shear of the sample. The maximum force, tensile strength, shear strength, bending strength, compression strength, elastic modulus, Poisson's ratio (special customization required), fracture elongation, yield strength, and other parameters are calculated. Conduct tests and provide testing data in accordance with international standards such as GB, MT48-87, CECS22-2005, ISO, JIS, ASTM, DIN, etc.
