The NDW series microcomputer-controlled material torsion testing machine is manufactured in accordance with the standards of GB/T2611-2007 "General Technical Requirements for Testing Machines", GB/T10128-2007 "Metal Torsion Testing Method at Room Temperature", YDT 988-2015 "Communication Optical Cable Junction Box", YD/T 814.1-2013 "Optical Cable Junction Box - Part 1: Outdoor Optical Cable Junction Box", and YDT 2150-2020 "Optical Fiber Distribution Box". This equipment is suitable for testing the mechanical torsion resistance of optical cables. By applying positive and reverse torsion forces, for qualified optical cables, it is required that the optical fibers do not break, the attenuation change of the optical fibers does not exceed the values specified in the detailed specifications of the optical cable products, the optical cable sheaths do not crack, and the core components of the optical cables do not damage.
Applicable standards: National Standards, ASTM, and other domestic and foreign standards. This machine has an attractive appearance, is easy to operate, and has stable and reliable performance.
The microcomputer-controlled torsion testing machine produced by our company combines advanced foreign control technology and exquisite appearance design. It uses high-precision ultra-wide linear guides from Taiwan's ABBA Company and ultra-thick mainframe steel plates to form a high-strength mainframe. It uses AC servo motors as the output power source to transfer to the efficient cycloidal pinwheel reduction system, thereby achieving high-performance torque and torsion angle output and control.
The control system adopts the world's popular high-speed PCI2.2 standard parallel bus design, uses amplifiers from BB Company in the United States, high-speed analog-to-digital converters from AD Company, and CPLD to form a data acquisition system and a high-precision torque sensor to form a measurement system. The software is written in the world's relatively popular C.NET advanced language and is upgraded simply and quickly.
The professional software of the testing machine can automatically calculate the maximum torque, torsional strength, upper and lower yield torque, specified non-proportional torque, shear modulus, etc. of data and indicators. The computer control system controls the test process and processes the data in accordance with the requirements of corresponding national standards, and the test reports can be in various forms such as WORD and EXCEL.
This machine is pollution-free, has low noise, high efficiency, and a wide speed adjustment range. It is suitable for testing the torsional performance indicators of various metals, non-metals, and composite materials, and fully complies with the requirements of relevant national standards.
This machine is widely used in material inspection and analysis in industries such as building materials, aerospace, mechanical manufacturing, wire and cable, rubber and plastic, automotive manufacturing, shock absorption systems, etc. It is an ideal testing equipment for research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commercial inspection and arbitration departments.
