Whether interest is in fatigue or development tests for steering sub-systems, BIA provides the most adapted installation to designers or steering components manufacturers.
Since most steering systems use electric or hydraulic power system, full communication under CAN protocol is available. In addition, BIA also offers a real turnkey solution by providing a climatic module.
STEERING COLUMN CHARACTERIZATION
To characterize steering column, an electric actuator is used to simulate steering wheel actions. On the output side, several modules had been developed to measure:
• Twist rigidity by applying torque on rack side
DYNAMIC EVALUATION BENCH
Additionally, hydraulic actuators can be added in order to apply loads on steering rack and to simulate wheel loads. Many tests can then be performed.
STEERING COLUMN FATIGUE
For fatigue & durability tests, steering column is adjusted in height and angle. Two hydraulic rotating actuators are positioned on wheel and rack side. They are used to drive steering column up to 150 N.m in static tests, whether in dynamic tests frequency can reach 10Hz. In addition, another linear actuator aims at oscillating on rack side, at a 10Hz frequency.
