The invention describes a test rig (1) for testing a component (20, 21), which test rig (1) comprises an adjustable radial weight arrangement (11, 12) mounted on a rotatable shaft (10); a driving means (13) for rotating the shaft (10) at a shaft rotational velocity (É); and an adjusting means (15, 150) for adjusting the centre of mass (CM_RW) of the adjustable radial weight arrangement (11, 12) relative to the shaft (10) while the shaft (10) is rotating. The invention further describes a wind turbine test setup (2) for testing components (20, 21) of a wind turbine, which wind turbine test setup (2) comprises such a test rig (1) mounted to a component (21) such that centrifugal forces (Fc) generated by the rotating radial weights (11, 12) during operation of the test rig (1) are transferred as lateral forces (F WT ) to the wind turbine component (21) under test. The invention also describes a method of testing a component (20, 21), which method comprises mounting such a test rig (1) to the component under test (20, 21) and operating the test rig (1). |
