Unparalleled Testing Capacity
Testing for Bending and Torsion
The SinusJet GEN 4.0 offers advanced capabilities: bending tests according
to EN 13262, torsion tests, or combined loading with separate control for
both natural modes.
Shortest Possible Response Time
The intelligent electronic control enables testing of rapidly changing load
scenarios (including crack propagation tests).
High Compatibility
Floating Specimen Design
The horizontal and symmetrical design of the test stand allows for testing
both sides of the specimen simultaneously, without interruption or the need
for reconfiguration between tests.
Innovative Clamping System
The innovative clamping system enables quick and easy specimen changes.
The specimens themselves do not need to be machined or equipped with special
clamping discs. The machine is compatible with standard wheelsets that meet
their final specifications.
Speed and Efficiency
High Testing Frequencies
The ideal frequency range of the SinusJet GEN 4.0 is between 40–60 Hz.
Economical Operation
All specimens are excited close to their natural bending and torsion frequencies.
This allows the test stand to generate the highest dynamic loads with low
motor power (10 kW max.). The maximum test moment is 250 kNm (bending) and
100 kNm (torsion).
