It has three control modes: stress control, strain control, and displacement control. During the test process, the three modes can be smoothly switched according to the set program. It can automatically obtain test parameters such as ReH, ReL, Rp0.2, Fm, Rt0.5, Rt0.6, Rt0.65, Rt0.7, Rm, E, and can conduct tests and provide data according to international standards such as GB, ISO, DIN, ASTM, JIS, etc. Widely used in industries such as aerospace, petrochemicals, plastics and rubber, metal materials, construction engineering, as well as higher education institutions, research institutions, technical supervision, quality inspection stations, and other departments. Meet or exceed national and international standards related to material testing systems: GB/T16491-2008 Electronic universal testing machine GB/T2611-2007 General Technical Requirements for Testing Machines JB/T6146-2007 Technical Conditions for Stretchers JJG475-2008 Metrological Verification Regulations for Electronic Universal Testing Machines JJG139-2014 Verification Regulations for Tensile, Pressure, and Universal Testing Machines 2. Overview of Product Structure 2.1 Host Structure Adopting high-strength self-lubricating guiding light bar to fix the upper crossbeam and worktable, forming a high rigidity frame structure, while ensuring linear motion of the crossbeam, ensuring coaxiality, and reducing differences in measurement data. Adopting Yifu high-precision preloaded ball screws and heavy-duty bearings to ensure long-term zero clearance operation of the equipment, the two ends of the screw nut are equipped with dust-proof sealing rings to ensure that no dust, impurities, etc. enter the screw nut during operation, thus ensuring the working life of the screw nut. The accuracy and repeatability of the test results are effectively guaranteed.
* The elaborately designed power transmission adopts Panasonic AC servo motors and silent synchronous belts, which are reliable,require little maintenance and have excellent force/speed characteristics. This ensures that the transmission system is efficient, smooth and low-noise, and guarantees that the relative error limit of the speed indication is within ±0.20%. 2.2 Test force measurement device It adopts high-stability and high-precision strain-type force sensors, combined with a high-stability measurement system, ensuring that the resolution remains constant throughout the entire range and guaranteeing that the relative error limit of the test force indication is within ±0.50%. Multiple sensors can be automatically switched for use to achieve a wide range of test force measurement. 2.3 Displacement measurement device Displacement measurement is carried out using brand photoelectric encoders, with a minimum displacement resolution of 0.015um. 2.4 Microcomputer Control System The brand computer is adopted as the main control to complete the functions of setting the test parameters of the entire machine,controlling the working status, data acquisition, processing and analysis, storage, and printing. Supports Windows98,Windows2000, Windows-Me, multi-language selection and switching, and the test mode can be configured with various test standards such as GB, DIN, JIS, ASTM, ISO, etc., or self-developed test standards. 2.5 Fixture It adopts a detachable standard connector, supports special fixtures for various reliable materials, and is easy to operate. 2.6 Safety Devices The emergency stop control switch, when pressed in case of an emergency, can reliably lock the equipment.
