Servo-Hydraulic 4-Post Test Bench

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

Possible applications of the test bench include:

  • Testing of the durability of individual components
  • Investigation of e.g. squeak and rattle noise
  • Simulation of rolling noise excitation in the vehicle (up to approx. 150 Hz)
  • Comfort testing (e.g. engine vibration or micro-jitter in convertibles)
