Vertical test bench

Motivation

Road excitations lead to vibrations of the entire vehicle and the mounted components

The resulting vehicle movements, vibrations and noises affect the driving and acoustic comfort of the vehicle occupants

Effect of road excitations on vehicle motion and vibrations can be tested under laboratory conditions

Nominal force per cylinder: 16 kN

Maximum cylinder stroke: 250 mm

Feed pressure: 280 bar

Maximum wheelbase: approx. 3.10 m

Maximum track width: approx. 1.66 m

Road unevenness is measured or calculated using mathematical approximation methods

Vehicle is positioned with wheels mounted on four hydraulic stamps

Simulation of road excitation by moving the hydraulic rams in and out → Measurement of the vehicle reaction

For subjective driving comfort evaluation, performance of subject studies

Objective and subjective ride comfort evaluation

Evaluation of damping and suspension characteristics

Development of new chassis control systems and functions

Evaluation of chassis control behavior

Objective and subjective evaluation of ride comfort, damping and suspension characteristics, and chassis control behavior
