Elastomer Test Stand BIA Turnkey Test Systems Hexapod
Item No.: PT-065
Designation: Elastomer Test Stand
Manufacturer: BIA Turnkey Test Systems
Fodewhdnhopfx Abhjfu

Description:
Test stand for determining and analyzing
mount characteristic curves and values at vehicle operating points
mount characteristic curves and values at operating points under specified temperature conditions
mount behavior under operational loading (compression set, change in characteristic curves)
functional noises at operating points
on elastomer mounts in the chassis/drivetrain area

Test specimens are clamped between an upper fixed plate and a lower mobile plate.
The mobile 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 the distance between the two plates to be adjusted,
enabling a wide variety of test specimens and fixtures to be clamped.

Mys ±10° 360°/s 50 Hz 3.75 kNm
Mzs ±25° 580°/s 50 Hz 3 kNm

Hydraulic Hexapod:
The hydraulic hexapod consists of 6 hydrostatically mounted hydraulic cylinders.
These have a cross-section of 12.53 cm².
Each cylinder is fitted with two parallel servo valves (38 l/min).
The six cylinders drive the mobile plate via six connecting rods.
The connecting rods are equipped with 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 by means of a linear actuator. The actuator consists of an electric motor,
a gearbox, and a leadscrew system. The linear actuator is fitted with an absolute encoder,
which is mounted on the gearbox input shaft.

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