Tests and activities of the Laboratory

Bolt hole resistance test
Functional tests

A test that measures the resistance to the deformation of the bolt holes of the steel wheel.

Corrosion tests (salt spray)
Functional tests

A test to verify the corrosion resistance of the surface-treated wheel subjected to extreme conditions.

Impact test (wheel with tyre)
Functional tests

A resilience test to evaluate the resistance of alloy wheels subject to impact through a collision simulation.

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.

Rim-rolling test (wheel with tyre)
Functional tests

A fatigue test that allows to evaluate the wheel resistance during rolling under load, as on a road drive.

Rotating bending
Functional tests

A fatigue test with rotating bending moment that simulates the load condition to which the wheel is subject to when in use.

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
Dimensional measurements

3D coordinate-measuring machine for single measures in manual or automatic mode, profiles and surface scans.

Profile scanning (profilometer)
Dimensional measurements

A machine to record profiles by means of a touch-probe for the 2-dimensional comparison of real profiles with theoretical ones.

Road simulation on biaxial test bench | MTS
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.

Strain-gauge analysis
Simulation and numerical experimental correlation

A test that evaluates the surface stress of a component subjected to a load by measuring the material surface strain.
