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:
Fpodpfx Abewhdnheken
- 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 loads (compression set, characteristic curve changes)
- Functional noise in operating points
on elastomer mounts in the chassis / drivetrain area

Test specimens are clamped between a fixed upper plate and a movable lower 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 the distance between the two plates to be adjusted, enabling a wide range of test specimens and fixtures to be accommodated.

Hydraulic Hexapod:
The hydraulic hexapod consists of 6 hydrostatically supported hydraulic cylinders. These have a cross-section of 12.53 cm². Each cylinder is equipped with two parallel-mounted 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 is supplied 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 screw nut system. The linear actuator is equipped with an absolute encoder, mounted on the input shaft of the gearbox.

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