Task:
Fatigue strength test of torsion spring bars with a maximum length of 1500 mm at a maximum torque of 4000 Nm.
Solution:
- Mechanical design
- Base frame with base plate and integrated T-slot rails
- Drive unit with DC motor 15 kW
- Double eccentric with a maximum adjustment of ± 43.5°
- Bearing system with connecting rod extension and torque measurement
Technological test setup
Torsion bars can be supplied with an adjustable preload of up to 2000 Nm with an alternating load of max.
± 2000 Nm can be applied.
The test frequency is a maximum of 10 Hz.
To achieve the torsional moments, the torsion bar can be rotated by a maximum of ± 43.5°.
The torques that occur are recorded and monitored.
