Vibration Testing Machines - Model 208 - 1

Friction coefficient testing machines clamp force and then exposed, at a variable frequency (depending on the model), to dynamic transverse loading. The temporal variation of the clamping force and the release angle (optionally) are directly presented during the test. The graphical plotting immediately provides the user with quality-relevant information on the release behaviour of the bolted connection. Vibration testing machines Bolted connections in rail networks and trains, as well as in vehicles and machinery, are exposed to various vibration levels during operations. These are caused by irregularities in the subgrade or by engine vibrations. During operations, these vibration loads occur over extended periods of time and with differing dynamics. The vibration intesting machine acc. to Junker is designed for dynamic testing of fasteners under transverse loading. It permits, among other things, control in accordance with DIN 65151. The test specimens are tightened in the machine with a dened Technical designs / model Screw dimensions Sensor clamp force Sensor shear force Release angle sensor (optional) Transversal stroke Frequency shear force Accuracy class Measurement uncertainty force Measurement uncertainty stroke ≤ 0.5 % of indicated value ≤ 1 % of indicated value Combined error Supply voltage Working table Electrics / Electronics Safety device EC – Certicate of Conformity 230 V / 1P+N+PE Option Desktop case yes yes Measurement range extensions T208.ALC.100/20 T208.ALC.100/20 T208.ALC.100/20 Screw dimensions M5…M10 M5…M10 M5…M10 Sensor clamp force 2…100 kN 2…100 kN 2…100 kN Sensor shear force 0.4…20 kN 0.4…20 kN 0.4…20 kN Measurement range extensions T208.ALC.300/30 T208.ALC.300/30 Screw dimensions M10…M18 M10…M18 Sensor clamp force 6…300 kN 6…300 kN Sensor shear force 0.6…30 kN 0.6…30 kN Parameters: Axial force, shear force amplitude, shearing distance amplitude effective, count of cycles, release angle (optional)
