The invention discloses a corrugated pipe elastic load equivalent device, relates to the technical field of spaceflight, and aims at simulating the real state of a corrugated pipe in the flight process of an aircraft and achieving the purpose that the bending rigidity of a corrugated pipe simulation part is consistent in the ground testing process. The corrugated pipe elastic load equivalent device comprises a corrugated pipe simulation piece, the corrugated pipe simulation piece is provided with two opposite end faces, one of the two end faces is used for being connected with a rack of an engine, the other end face is used for being connected with a spray pipe of the engine, and the corrugated pipe elastic load equivalent device further comprises a swing mechanism and two fixing connecting pieces. The corrugated pipe simulation piece is provided with a spiral groove which spirally extends along the distribution direction of the two end surfaces, and the corrugated pipe elastic load equivalent device further comprises two mounting structures. The corrugated pipe elastic load equivalent device provided by the invention is used in spaceflight experiments.
