Abstract
A test bench for wind turbines, comprising a test bed (1) on which the assembly (6) to be tested is mounted, and load application means for applying loads on said assembly. The assembly (6) to be tested is mounted on the foundation through a cylindrical support (5), provided with an upper rotary flange, which can be operated by means of a series of geared motors. The load application means comprise a fixed structure (7) anchored to the foundation, a mobile structure (8) which is anchored to the assembly (6) to be tested and a series of actuators (9) relating the mobile structure (8) with the fixed structure (7).
Claims8
A test bench for wind turbines, comprising a test bed (1) on which the assembly (6) to be tested is mounted, load application means for applying loads on said assembly, a data collection system, and a general control system, characterised in that the assembly (6) to be tested is mounted on the foundation (1) through a cylindrical support structure (5) which is anchored to said foundation (1) and includes a rotary flange (35) for the anchoring of the assembly to be tested, a geared ring (36) fixed to the rotary flange, a series of geared motors (38) with pinions (37) engaging with the geared ring (36), and a series of brakes (39) capable of acting on a brake disc (40) solidly connected to the rotary flange;
- and in that the load application means comprise a fixed structure (7), which is anchored to the test bed, a mobile structure (8) which has means for anchoring it to the assembly to be tested, and a series of actuators relating the mobile structure with the fixed structure (7).
A bench according to the previous claims, characterised in that the mobile structure (8) is of a three-dimensional configuration, of an approximately hexagonal truncated pyramidal shape, on the major base of which the anchoring means (15) to the assembly to be tested are situated in a central position, and the jointing points (13) of the dynamic actuators (12) being in a position coinciding with its vertices.
