What is torsion testing? According to the Encyclopedia of Biomedical Engineering, torsion testing is a mechanical testing that involves the twisting of a sample material along its axis.It is an important test for collecting data regarding torsional shear stress, maximum torque, shear modulus, and breaking angle of a material or the interface between two materials.Torsion testing can be split into two distinct categories: testing raw materials like metal wires or plastic tubing to determine properties such as shear strength and modulus, or functional testing of finished products subjected to torsion, such as screws, pharmaceutical bottles, and .Audi Torsion Test Equipment . Click here to read more about torsion, why we test for it, and how torsion affects shielded cables. Drag Chain Tests. Drag chain cables are always on the move: high accelerations, tight bending radii and constant abrasion are continuous strains on the material. Our drag chain test systems allow us to apply .

Volume 1. Yusuf Khan, in Encyclopedia of Biomedical Engineering, 2019. Torsion testing. Torsion testing involves the twisting of a sample along an axis and is a useful test for acquiring information like torsional shear stress, maximum torque, shear modulus, and breaking angle of a material or the interface between two materials. Typically a longitudinal sample is placed in a .We offer bend test and torsion test devices for cables or wires in cooperation with our partner CCONRADT. The “flex life test” (or alternate bending test) is based on the standard specification ASTM B470. During the test, cables or wires under test are alternately bent over defined radii in cycles. The defined bending angle, weight load and . The torsion lever consists of a metal part containing a cable connector up to 30 mm of diameter and a lug at the opposite end of the metal part, where there is a Z-type (tension and compression) load cell with a capacity of 98.07 N (10 kgf) and gain of 2 mV/V, with a hinged piece used for traction.. The traction was performed manually at the end of the lever, allowing .

This test is best performed on a torsion testing system such as Instron's MT Series with Bluehill Universal software. Gripping solutions depend on the diameter and hardness of the material, and can range from collet grips for softer materials to chucks for harder materials. The jaw faces are recommended to have a hardness greater than 55 HRC.Learn more about our cable flex testing process, including our standards, including torsion test and continuous flexing. Contact us today to learn more. Skip to Header Skip to Main Content Skip to Footer . United States . . Several cable samples are cut to a specified length, allowed to relax and then are straightened if any bends or curves . More unique is a test tower for torsion testing cables and wires used in wind turbines. Machines stress cables and wires with torsion to ± 150°/m. This test condition pushes cables to greater extremes than they would ever experience in real applications. In the 27-ft (8-m) tall girder mast, a wind turbine’s cable loop is reproduced 1:1 and . Hence we arrive at the Quabbin Industrial Ethernet Torsion Test. Torsion tests were performed on Quabbin industrial Ethernet cables. The test is a 360-degree twist total per cycle (180° in each direction) over 34” of cable at 71 cycles per minute. . As you can see, Quabbin cables pass the torsion test for tough applications and high-cycles .

A very simple cable is made up of a solid wire and a plastic outer jacket. This cable can bend and retains this bending – as long as you don’t bend it too often, as otherwise the wire breaks. Simple cables like these are used in house installations. Once permanently installed, the cable remains in place for decades untouched.
