Combination deformation mechanics experiment apparatus

Abstract

A combination deformation mechanics experiment apparatus is disclosed. One end of a thin walled tube is fixed on a vertical arm of a rack so as to form a solid supported end. A first ball bearing is sleeved on the thin walled tube. An upper surface and a lower surface of the thin walled tube are sticked with strain rosettes respectively. A cantilever end of the thin walled tube fixes a sector framework. An upper vertex angle of the sector framework is clamped with a flexible cable, a flexible cable tandem connection tension sensor and a spinning wheel loading mechanism. A lower end is fixed on a pedestal of the rack. A stud, whose height can be adjusted continuously, is arranged under the first ball bearing. A double U-shaped position of the stud is provided with two second ball bearings. The stud and a spinning wheel are spinningly connected to a support. A spacing taper pin is installed on the support and is guided into a spacing chute of the stud. By using the apparatus of the invention, multiaspect experiment projects can be realized. There are a plurality of mechanics model boundary conditions, many kinds of test conditions, various kinds of test schemes and changeable group bridge forms. A design is novel and reasonable. A structure is compact. Operation and usage are convenient. The apparatus has many other advantages.
