Test Bench for Scaled Bearings

The BEAT1.1 (Bearing Endurance and Acceptance Test) is a test bench for scaled wind turbine bearings, designed and supplied by IDOM to Fraunhofer IWES already fully operational in Hamburg.

The BEAT1.1 is based on the innovative design developed by IDOM for the BEAT6.1, a similar test rig conceived for large bearing testing.
This includes a Stewart Platform powered by 6 hydraulic servo-actuators that are able to apply loads up to 250 KNm and 1 MN. The test bench is able to apply dynamic loads with a frequency of 2 Hz, thus enabling the performance of highly accelerated life tests. The features of the bench are complemented by an additional electric pitch system, based on a pinion and crown mechanism powered by an electric motor, that simulates the pitch movement of the wind turbine blade.
