Abstract
In order to better solve anti-impact problem of hydraulic support, based on the previous study of anti-impact device by the author’s team, a thin-walled tube component with vertical strip which works as an energy absorbing component is designed and simulation model of the component is established, and energy absorption characteristics of the component is studied. Experimental verification is done and the simulation model is optimized based on the experimental data. Based on the above works, parameters of the component are re-optimized and energy absorption characteristics of the component are tested. Through supporting reaction force–deformation curve of the thin-walled tube component with vertical strip, it can be seen that deformation stability of the component is high, and the initial peak force difference ratio of energy absorbing components before and after structural optimization is reduced from 4.8% to 1.04%. The results show that energy absorption characteristics of the thin-walled tube component with vertical strip are further improved, and accuracy of the simulation model is also further improved.
