Abstract

A double-direction vibration resistant test bed comprises an upper platform, a middle platform and a lower platform which are sequentially arranged in parallel from top to bottom, the middle platform is arranged on a horizontal rail on the upper surface of the lower platform, the upper platform is arranged on a horizontal rail on the upper surface of the middle platform, and a certain included angle is formed between the horizontal rail on the upper surface of the lower platform and the horizontal rail on the upper surface of the middle platform; the upper platform and the middle platform are respectively connected with a corresponding power mechanism, the upper platform and the middle platform are respectively driven by the corresponding power mechanism to move along the corresponding horizontal rail, and one end of the upper platform and one end of the middle platform are respectively connected with a spring set which can generate reverse acting force when the corresponding power mechanism drives the corresponding platform to horizontally move. The double-direction vibration resistant test bed resolves the technical problems that a vibration resistant simulator stand in the prior art is single in input mode, complex in structure, relatively high in cost, poor in reliability and the like, and is simple in structure and principle, easy to operate, easy to obtain, relatively low in cost and suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of civil engineering experiment equipment, in particular to a test bench device capable of outputting bidirectional vibration loads. Background technique [0002] In terms of space, the ground motion during an earthquake can be decomposed into six components, including 3 translational components and 3 rotational components. At the same time, structures exhibit spatial motion under the action of multidimensional earthquakes. The degree of this spatial effect depends on The degree of irregularity and integrity of the structure, even if it is a regular and symmetrical structure, due to reasons such as materials and construction, the vibration of the structure under the action of strong earthquakes is definitely not regular and symmetrical, and the degree of irregularity and integrity will occur over time Variety. The analysis of seismic damage data shows that the action of two-way horizontal earthquakes will f...
