Elastomer Test Bench BIA Turnkey Test Systems Hexapod

Item No.: PT-065
Designation: Elastomer Test Bench
Manufacturer: BIA Turnkey Test Systems

Description:
Test bench for determining and analyzing
bearing characteristic curves and values at vehicle operating points
bearing characteristic curves and values at operating points under specified temperature conditions
bearing behavior under operating loads (compression set, change in characteristic curves)
functional noise at operating points
on elastomer bearings in the chassis/drivetrain area

The test specimens are fixed between an upper fixed plate and a lower movable plate.
The movable plate 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,
enabling the clamping of a wide variety of test specimens and mounts.

Hydraulic Hexapod:
The hydraulic hexapod consists of 6 hydrostatically mounted hydraulic cylinders.
These have a cross-sectional area of 12.53 cm².
Each cylinder is equipped with two parallel servo valves (38 l/min each).
The six cylinders drive the movable plate via six connecting rods.
The connecting rods have a hydraulic spherical 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 plate
can be adjusted using a linear actuator. The actuator consists of an electric motor,
a gearbox and a lead screw system. The linear actuator is equipped with an absolute encoder
which is mounted on the input shaft of the gearbox.

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