Press able to measure force, pressure and displacement of the actuator.

Non-destructive tests (liquid penetrant inspection)
Functional tests

Non-destructive tests by means of liquid penetrant inspection to assess materials defects with no product damage.

 

Rim deformation test
Functional tests

A test for steel wheels for the evaluation of rim deformation by simulating a frontal contact with obstacles.

Harmonic response test
NVH (Noise, Vibration, Harshness) tests

A test to evaluate the harmonic response of the wheel, recording generated frequencies and vibration modes, and how this influences the dynamic behaviour of the vehicle.

Wheel stiffness test (static)
NVH (Noise, Vibration, Harshness) tests

A test to measure the static stiffness of the wheel.

Brake envelope (contour) test
Dimensional measurements

A test for the detection of the deformation inside the wheel under load.

Coordinate-measuring machine

Simulation and numerical experimental correlation

A road simulator that applies radial and lateral loads with dynamic variations during the test to evaluate the wheel fatigue resistance.

Road simulation on test bench
Simulation and numerical experimental correlation

The dynamometric wheel is mounted to measure the loads and forces the wheel is subjected when operating.

Shifting fork fatigue test

Materials analyses

Ideal system for the testing of components and materials such as plastics, elastomers, aluminum, composites, steel, super alloys and more.

Metallography

Materials analyses

The SEM (Scanning Electron Microscope) is a very useful tool in micro and nano-structural investigation. It allows the study of high magnification of surfaces (fractures, topography).

Chemical Analysis - Optical Emission Spectroscopy (OES)
Materials analyses

The material to be analyzed is subjected to a powerful electrical discharge. Under the effect of this discharge, part of the surface vaporizes creating a cloud of excited ions that emit electromagnetic radiation.

Materials analyses

In a tensile test the specimen, usually a dog bone, is deformed by gradually increasing the axial load until failure.

Mechanics - Hardness
Materials analyses

The Vickers microdurometer is used to perform high precision hardness tests (hardened surface layers, surface coatings of small parts, inclusions, second phases ...).
