Novel cylindrical hinge rotating bracket for static force loading experiment

Abstract

The invention discloses a novel cylindrical hinge rotating bracket for static force loading experiment. The novel cylindrical hinge rotating bracket for static force loading experiment mainly comprises a lower base, upper node plates and a clamp support, wherein the lower base mainly comprises a flat plate and a semi-cylindrical supporting part; the upper node plates mainly comprise an upper node plate I, an upper node plate II and an upper node plate II; the clamp support mainly comprises a screw, a lug plate, a baffle plate and a round reinforcing rib. The novel cylindrical hinge rotating bracket for static force loading experiment, disclosed by the invention, is simple to configure, convenient to manufacture and install, strong in loading force, capable of effectively stimulating the boundary condition of one-way hinge joint, suitable for static force loading experiment of compression members with various section forms such as a rectangular form and an H-shaped form, and can be widely applied to the experiment of shaft center compression members and eccentric compression members.

Description

technical field [0001] The invention belongs to the technical field of compression component experiments, and relates to a novel cylindrical hinged support for static loading experiments. Background technique [0002] In the compression member experiment, in order to simulate the boundary conditions of the hinged joint at both ends of the compression member, it is necessary to set the rotating hinge support at both ends of the compression member. Existing rotary hinge supports mainly exist in the form of knife hinges, pin shafts, etc., but the bearing capacity of the knife hinge support is small, and the pin shaft support often suffers from excessive friction when the force is large, causing the rotation to be subject to a relatively large limit. However, other bearings with large bearing capacity often have the disadvantage of excessive self-weight. Therefore, it is necessary to make a new type of rotating hinge support for static loading experiments that has a large beari...
