STUDY ON MECHANICAL PROPERTIES OF HONEYCOMB REGULAR HEXAGON DAMPER

Abstract

Traditional metal dampers have the advantages of easy processing, convenient production, and good mechanical properties. However, most of the traditional metal dampers are single design, and their application is limited by the size of the dampers. Based on the honeycomb metal damper, a honeycomb regular hexagon metal damper with a free connection is proposed in this paper. Firstly, the failure mechanism, hysteretic curve, skeleton curve, stiffness degradation curve, and energy dissipation curve of the single energy-dissipating supporting member and the triple two-row supporting member were obtained through the low-cycle reciprocating loading test. Then the R-O mechanical model was fitted to the skeleton curve obtained from the test. Then, three kinds of honeycomb regular hexagon dampers were modeled by ABAQUS finite element simulation software, and the finite element simulation results were compared with the test results. The results show that the energy dissipation support in this paper has a good bearing capacity and energy dissipation capacity, and the development trend of simulation results align with the experimental results. The energy dissipation capacity of the energy dissipation support can be improved, and the multi-section yield can be achieved by connecting multiple energy dissipation units.
