Elastomer Test Rig BIA Turnkey Test Systems Hexapod
Item No.: PT-065
Name: Elastomer Test Rig
Manufacturer: BIA Turnkey Test Systems

Description:
Test rig for determining and analyzing
bearing characteristic curves and values at vehicle operating points
bearing characteristic curves and values at operating points under specified temperatures
Rjdpfx Aewhdnhjchju
bearing behavior under operating load (settlement behavior, characteristic curve changes)
functional noise at operating points
on elastomer bearings in the chassis/drive system

Test specimens are mounted between an upper fixed platen and a lower mobile platen.
The mobile platen is driven by a hydraulic hexapod.
The fixed platform is attached to the test structure via a 6-axis force sensor. A linear actuator
allows adjustment of the distance between the two plates,
to accommodate a wide variety of test specimens and fixtures.
Degrees of freedom Amplitude Velocity Frequency Dynamics
Xs ±25 mm 1.5 m/s 85 Hz 25 kN
Ys ±25 mm 1.3 m/s 85 Hz 25 kN
Zs ±25 mm 0.8 m/s 85 Hz 50 kN
Mxs ±15° 340° / s 50 Hz 3.75 kNm
Mys ±10° 360° / s 50 Hz 3.75 kNm
Mzs ±25° 580° / s 50 Hz 3 kNm
Hydraulic hexapod:
The hydraulic hexapod consists of six hydrostatically mounted hydraulic cylinders.
These have a cross-section of 12.53 cm².
Each cylinder has two parallel servo valves (38 l/min).
The six cylinders drive the mobile plate via six connecting rods.
The connecting rods have a hydraulic ball joint at their base. The oil pressure for this
hydrostatic bearing comes directly from the cylinder.

Linear actuator:
The distance between the upper and lower plates
can be adjusted using a linear actuator. The actuator consists of an electric motor,
a gearbox, and a screw-nut system. The linear actuator is equipped with an absolute encoder.
This is attached to the input shaft of the gearbox.

Hydraulic actuator:
The hydraulic cylinders are equipped with magnetostrictive position sensors.
