Provided in the invention is a dynamic load factor experimental device for solving a plurality of beams. The dynamic load factor experimental device comprises a first experimental table; a vertical boss is integrally formed at the left side of the first experimental table; and a U-shaped iron hoop member is fixed at the lower side of the right side of the vertical boss. A horizontal connecting groove is formed in the middle part of the right side of the right upper surface of the first experimental table. Besides, a first vertical mounting frame is fixedly connected to the upper right surfaceof the first experimental table; and a first clamping device is installed at the upper side of the first vertical mounting frame. A tack is arranged on the upper surface of the vertical boss and is arranged horizontally in a left-right direction; a power spring is fixed at the left end of the track; the right end of the track extends to the right side of the vertical boss; a first lead block is arranged in the track in a sliding manner; a tachymeter is arranged at the right end portion of the track; and central lines of a vertical connecting groove, the first vertical mounting frame, the firstclamping device and the track are located in the same vertical plane in the left-right direction. Therefore, the dynamic load factor experimental device has advantages of scientific design and reasonable structure; and impact experiments of various beams can be met and the demand of mechanical experiment teaching can be satisfied.
