Steering Sub System Test This machine offers efficient and flexible test solution to perform dynamic tests on complete steering sub-system. By simulating its real environment, the test system eval!uates accurately the steering behavior in any configuration. By simulating loads applied on steering wheel and steering rack, This test machine can performed relevant dynamic tests : Violent wheel swerve :. acceleration up to 15 000 °/s with 6 000 N resistance force on rack  Wheel release after wheel turn : steering column behavior after wheel releasing, under real load on the rack Frequency characterization (direct or reverse) : system response measurement under vibration (force/displacement) Derating : power electronics failure analysis For characterization of steering column, two optional modules are available to perform measurement of twist rigidity, friction torque and homokinetic defects.

The flow periodicity that could be affected by gravity is checked visually so we can assure the veracity of simulating only a sector of the actual plate for computational efficiency. Thermocouples monitor oil temperatures as it enters the plates and when it is ejected out from the outer radius and a heater warms the oil if needed. The temperature rise resulting from viscous
dissipation between the plates is small, at most 2C, and
hence viscosity can be assumed to be constant.
 A 15 hp inverter-type motor 400–3450 rpm drives the
rotating clutch plate. Centrifugal pump supplies oil throughout the system and the pump work and friction work between the plates increases the system temperature accordingly. The oil flow rate is precisely controlled by a displacement syringe pump that compresses two 50 ml syringes at a prescribed speed. When the inlet and outlet oil temperatures reach steady state, a valve attached to the centrifugal pump is closed to stop oil supply and the accurately metered, constant displacement syringe pump starts for the torque and optical measurements. A beam type single point load
cell measures the drag torque of the stationary plate.
Torque cell makes it possible to calculate the drag torque by multiplying the force measurement of the load cell by the moment length. A high-speed imager captures digital images through the transparent rotating plate at a rate of 4500 fps. A 500 W electrical heater installed in the oil sump allows experiments with elevated oil temperature.
Transparent quartz rotating disk plate allows visualization
of the flow pattern. The stationary plate is made of aluminum disk. To minimize the influence of the inner circular region, the stationary plate has a 4 mm depth very large compared to the clearances between the two plates that are 100 and 200 m step “d.” Five different stationary plates investigate the groove effect on drag torque. Four plates are made by two different
numbers of grooves 40 and 80 and 2 groove depths 200 and 400 m combinations and a no groove plate flat disk is tested for generic experiment.

 The circulation pump helps to maintain a steady oil temperature throughout. The syringe pump is used whenever a fixed flow rate of oil is to be prescribed.
