Torsion Testing Machine WNJ Series │ WNJ-100~2000 1 Introduction WNJ Series Computer Controlled Torsion Testing Machine or Twist Testing Machine are used to determine the torsional properties of various components – from fasteners to biomedical devices. HUALONG offers a full range of torsion load frames range from 100 to 30,000 Nm, higher capacity and other longer length models are available upon request. These uniquely superior torsion testers provide loading and weighing capabilities in both directions of rotation. This feature makes it possible to conveniently determine not only the ultimate torque load of a specimen, but how that specimen behaves under conditions of continuous or intermittent torque loading in both directions. Essentially, each torsion tester comprises a variable speed drive loading system and a digital control and indicating system in a fixed unit. The weighing head with its strain gage torque sensor is mounted on a moveable unit which can positioned on the rails to accommodate specimens of varying lengths. HUALONG TestWorld-WNJ V4.1 allows complete machine control along with capture and analysis of the resultant torsional test data, showing the material behavior throughout the test. Application ASTM E143: Standard Test Method for Shear Modulus at Room Temperature; ASTM F543, ISO 6475: Implants for surgery-Metal bone screws with asymmetrical thread and spherical under-surfaceMechanical requirements and test methods. Software system: Software package under Windows platform of English version with straightforward interface. Dynamic display of data: The test data during the test process (such as: torque, twist angle, stroke and so on.) will be real time displayed. Ability to recall, report, and rescale curves. User configurable testing method: specimen information, controlling methods and measuring method can be configured saved according to different materials for future needs. User configurable report: Ms. EXCEL report formats can be freely tailored to different report template. Multiple control modes: It has stroke control, torque control, twist angle control, stress control, and shear strain control and so on. Test conclusion: Torsional strength ( ), yield strength ( yield strength ( Torsion fixtures capable of holding a wide variety of materials, products, and components. Fixtures can be customized for special applications. Adjustable crosshead locking system allows crosshead to be free-floating or fixed during testing. ), lower yield strength ( sl ), Max. Torque (Tb), proof stress of non-proportional torsion ( proportional shear strain ( max ), shear modulus (G), twist angle for the corresponding torque , and torque for the corresponding twist angle and so on. Multiple statistics function: Average value, standard deviation, coefficient of variation, Max. Value, Min. Value, and median value and so on. User can edit and define the test results on curve if the some data seem to be uncertainly
