The ZWARP technology can be introduced to examine the fatigue behaviour of wheels and hubs of commercial vehicles. The accelerated life testing proves the structural durability of the wheels in service by simulation of realistic loading. Furthermore ZWARP is very common in the sector of vehicle and wheel manufacturers.

Since the first developed and patented ZWARP test rig hardware in the 1980’s Fraunhofer LBF is the world leading provider for R&D services in the field of biaxial wheel/hub fatigue test technology having expertise both in test rig hardware as well as in load file development since decades.
