Technology meets future.

Test device for torsion bars

The fatigue strength test of torsion spring bars with a length of up to 1500 mm and a torque of 4000 Nm is carried out using a test stand that enables an adjustable preload of up to 2000 Nm and an alternating load of ±2000 Nm with a test frequency of up to 10 Hz, whereby the torques occurring are recorded and monitored.

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.
