Servo-Hydraulic 4-Post Test Bench

The servohydraulic 4-post test bench at FKFS enables vertical excitation for all four wheels of a vehicle. The posts can be equipped with linear guides in order to avoid lateral force components on the wheels.

Some applications of the test bench include:

  • Testing the durability of individual components
  • Investigation of noise (e.g. rattling and creaking noises)
  • Simulation of rolling noise excitation in the vehicle (up to approx. 200 Hz)
  • Comfort testing (e.g. engine vibration or micro-jitter in convertibles)
