w+b Materials Testing Systems Closed-Loop Controlled Rotary Bending Fatigue Testing Machines UBM Series w+b offers a complete series of closed-loop controlled Rotary Beam Fatigue Testing Systems designed for applying a constant rotating load and bending moment on standard rod-like specimens in accordance with ISO 1143, DIN 50113 or BS 3518-2. The specimen has a round cross section and is subjected to dead-weight loading while swivel bearings permit rotation. The UBM series provides constant bending moment over the entire sample length with maximum stress on the circular test-section surface...

w+b Materials Testing Systems This series of UBM’s feature best in class spindle system suitable for high frequency testing. The machine is closed loop driven by a high responsive, water cooled spindle. The spindle on the opposite side is not powered and features extremely low friction so that the torque loading on the sample is minimized. To reduce the friction, minimize the torque loading on the sample, remove the heat and to extend the lifetime, the spindle is water-cooled. When connecting additional pressurized air a small overpressure avoids dust and dirt enters into the spindle. The...

w+b Materials Testing Systems The machines are closed loop driven / controlled by a high responsive AC motor with closed loop controller providing stable high speed even when line voltage fluctuations appears. No voltage stabilizer is needed. The system operates on a low noise level. To avoid any damage in the sample through torque peaks the system features a start procedure where the motor ramps slowly to its maximum speed, thus torque peaks that could invalid our test are avoided. Specimen Gripping System This UBM’s features Collet Chuck sample clamping system for cylindrical smooth shank...

w+b Materials Testing Systems Closed-Loop Controlled Rotary Bending Fatigue Testing Machines Series UBM with Load Cell instead of Dead-Weights The full line of rotary bending testing machines is also available with incorporated Force Transducer with digital closed loop force control and application software. In this case is the rotary bending machine is equipped with a high precision electronic load cell (instead of dead-weights) with electromechanical spindle drive and digital closed loop controller PCS8000. The spindle system and load cell are located on the rear side of the machine. The...

w+b Materials Testing Systems Statistical Analysis of Fatigue Data (SAFD) To ease the statistical evaluation of fatigue tests the software SAFD has been developed at the Institute for Materials Science (IWK) of the RWTH Aachen University. For practical statistical evaluations of fatigue tests we are offering the software interface to the SAFT statistical evaluation software. SAFD offers: • niversal evaluation of stress controlled fatigue tests in high cycle fatigue (HCF) and long life fatigue region (LLF) U • resentation of the evaluation results and the test data as S-N diagram (semi-or...

w+b Materials Testing Systems High Temperature Accessories for UBM Our Rotary Bending Fatigue Testing Machines Series UBM are beside of room temperature tests also well suited to conduct tests at elevated temperature in air. Depending on specimen dimensions and required temperature range we are offering different heating and clamping solutions To archive an accurate temperature gradient along the test section of the specimen during the test a appropriate heating zone length is required. This furnace is specifically optimized for the B use in combination with our rotary bending testing...

w+b Materials Testing Systems Slidable Thermocouple Arrangement Due to the nature of rotating bar bending fatigue testing, direct temperature measurement is not possible. For this the HTO-19 furnace comes along with a slidable thermocouple arrangement allowing to move the thermocouples close to the extension rods and the middle one close to the specimen. All thermocouples are spring loaded. Each thermocouple can be moved independently in horizontal position for adjustment purpose. Additionally all three (3) thermocouples can be moved together if further specimens are tested. Additional...
