Elastomer Test Rig BIA Turnkey Test Systems Hexapod
Ref. No.: PT-065
Description: Elastomer Test Rig
Manufacturer: BIA Turnkey Test Systems

Description:
Test rig for the determination and analysis of
bearing characteristics and values at vehicle operating points
bearing characteristics and values at operating points under specified temperatures
bearing behavior under operational load (compression set, change in characteristics)
operational noise at operating points
on elastomer mounts in the chassis/powertrain area

Test specimens are mounted between an upper fixed plate and a lower movable plate.
The movable plate is driven by a hydraulic hexapod.
The fixed platform is connected to the test structure via a 6-axis force sensor. A linear actuator
allows for adjustment of the distance between the two plates
to accommodate a wide range of specimens and fixtures.

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).
The six cylinders drive the movable plate via six connecting rods.
The connecting rods are equipped with a hydraulic spherical bearing 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 ball 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.
