The most complete laboratory road simulator for wheel & hub durability testing of passenger cars as well as heavy duty vehicles is the BiAxial Wheel/Hub Fatigue Test Machine which is using an inner drum as the moving ground.

The wheel assembly is loaded by vertical and lateral actuators which are capable to introduce service-like operational conditions such as straight driving on rough roads or heavy dynamic cornering. To guarantee the correct replication of conditions experienced by a vehicle in service, the wheel gets assembled on original wheel hubs.

Beside wheel/hub fatigue tests examinations regarding unintentional wheel bolt loosening or bearing failures can be performed.
