Computer Controlled Electro-Hydraulic Servo Universal Testing Machine
Introduction:
WAW-D series computer-controlled electro-hydraulic servo universal testing machine is an important instrument for testing the physical, mechanical, technological, structural, and internal and external defects of various materials and products. It can carry out tensile, compression, bending, and shear tests on metal or non-metal materials, and can automatically obtain the tensile strength, yield strength, specified non-proportional extension strength, elastic modulus, and other performance indexes of the materials tested. It can complete closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, constant rate strain, and so on.
Application:
It is widely used in universities, research institutes, inspection agencies, aerospace, military, metallurgy, machinery manufacturing, traffic construction, construction materials, and other industries for precision material analysis, material development, and quality control.
