The invention relates to a multifunctional test device for a rigid suspender of a fabricated arch bridge and a test method for simulating impact or explosion. The multifunctional test device comprises a test device body, and the test device body comprises a rigid suspender test piece; two ends of the rigid suspender test piece are respectively fixed with the first steel box concrete pedestal and the loading device, and the loading device is connected with a twisted steel bar or a steel strand penetrating through the second steel box concrete pedestal, that is, the loading device tensions the rigid suspender test piece through the twisted steel bar or the steel strand so as to simulate the axial stress state of the rigid suspender of the arch bridge; straining beams are arranged between the first steel box concrete pedestal and the second steel box concrete pedestal and on the two sides of the rigid suspender test piece respectively; an impact hammer or an explosive is mounted at any position of the rigid susp
