Detailed description of the invention
Below in conjunction with the accompanying drawings and the utility model is described further by embodiment.
Refer to Fig. 1, the present embodiment provides a kind of vertical viscoplasticity collision tuned mass damper structure, including the shell being made up of upper cover plate the 11st, lower cover the 12nd, first member plate 13 and right end plate 14, also including the mass being arranged in described shell, described mass includes that the 21st, horizontally disposed rigid rod is arranged at prismatic mass in the middle part of described rigid rod 21 and the 22nd, is arranged at the spherical mass 23 at described rigid rod 21 both ends；Described rigid rod 21 can be one, runs through described prismatic mass, or described rigid rod 21 is two, is individually fixed in the both sides of described prismatic mass 21, and its tail end is connected with spherical mass 23 respectively；Particularly, described rigid rod 21 is with the connection of spherical mass 23 for threadeding, i.e. the end of rigid rod 21 is provided with screw thread, spherical mass 23 is provided with the groove with described rigid rod 21 matching ends, and has been provided with internal thread.
