Aeroelastic model for concrete heat absorption tower wind tunnel test

The invention discloses an aeroelastic model for a concrete heat absorption tower wind tunnel test. The device comprises a bottom plate used for fixing an aeroelastic model during a test, a core beamis vertically arranged on the bottom plate; wherein the core beam is provided with a plurality of discs from bottom to top, the periphery of the core beam is further provided with a plurality of coatsfrom bottom to top, the coats are arranged on the outer walls of the discs in a sleeving mode and are detachably connected with the discs, a gap is reserved between every two adjacent coats, and eachgap is covered with an adhesive tape pasted to the two corresponding adjacent coats. The bending rigidity of the concrete heat absorption tower structure is simulated through the core beam; the discand the coat are weighted along the height according to the mass distribution of the actual structure; accurate distribution of rigidity and mass of the aeroelastic model is ensured, at least first three-order modes can be simul
