The invention discloses a method for verifying the bird strike resistance performance of a pitch link of a main blade of a helicopter, and belongs to the field of helicopter structural strength tests. The method is used for determining the performance of the pitch link of the main blade of the helicopter after bird strike damage is generated in the flight process. Aiming at the characteristics that the pitch link of the main blade of the helicopter is high in bird strike probability in low airspace, and damage is serous, the bird strike resistance performance of this kind structures is assessed accurately through the bird strike tests of the full size structure under simulated real working environment, fatigue life verification tests half hour after striking and residual strength tests, and it is guaranteed that catastrophic results cannot be generated even if bird strike occurs to the helicopter in the harshest flight process.
