Rubber shock insulation cushion for monitoring interface peeling and system for monitoring interface peeling thereof

Abstract

The invention discloses a rubber shock insulation cushion for monitoring interface peeling and a system for monitoring interface peeling thereof. The rubber shock insulation cushion comprises a plurality of rubber layers, a plurality of steel sheet layers, a plurality of shear type piezoelectric ceramic drivers, a plurality of shear type piezoelectric ceramic receivers, an upper sealing plate, a lower sealing plate, an upper connecting plate and a lower connecting plate, wherein the multiple rubber layers and the multiple steel sheet layers are alternatively staggered to form a main body of the rubber shock insulation cushion; the upper sealing plate and the lower sealing plate are respectively fixedly arranged at the upper surface and lower surface of the main body of the rubber shock insulation cushion; the upper connecting plate is fixedly arranged at the upper surface of the upper sealing plate, and the lower connecting plate is fixedly arranged at the lower surface of the lower sealing plate; the shear type piezoelectric ceramic drivers and the shearing type piezoelectric ceramic receivers are respectively distributed at both sides of at least one interface. The rubber shock insulation cushion has the advantage that a shear type piezoelectric ceramic sensor is applied to monitor the interface peeling in the rubber shock insulation cushion, so as to accurately monitor the slight change of the interface peeling degree.

Description

technical field [0001] The invention relates to the technical field of health monitoring of rubber shock-absorbing pads, in particular to a rubber shock-absorbing pad capable of monitoring interface peeling and an interface peeling monitoring system thereof. Background technique [0002] So far, most of the seismic isolation projects applied to building structures, bridges, and equipment at home and abroad have adopted the "laminated rubber bearing" seismic isolation technology. Buildings or bridges using this technology have successfully withstood the earthquake test in my country, Japan, and the United States. Therefore, it is a relatively mature seismic isolation technology that can be widely promoted and applied. The laminated steel plate and the rubber layer are tightly bonded to ensure the deformation constraint of the steel plate to the rubber, so that the rubber has a high vertical compressive bearing capacity and a certain tensile capacity, a large horizontal defor...

AI Technical Summary

Problems solved by technology

The failure and destruction of the rubber shock-isolating pad is largely due to the peeling of the interface between the rubber and the steel plate, but there is currently no effective method to monitor this situation in related fields
