Abstract

Abstract

In order to increase the energy absorption of the anti-impact hydraulic support and improve its safety, a lattice energy-absorbing device was designed. The specific energy absorption and unit mass support force of three typical lattice cells were studied with the finite element simulation. The pyramid structure was determined to be the best topology of the lattice cells. The three-factor and five-level orthogonal experiment was used to analyze the influence of their body height, body inclination width and body diameter on energy absorption and support force and to determine the best body structural parameters. The simulation analysis shows that the total energy absorption of the pyramid lattice energy absorbing device with the best structural parameters is 1 470 kJ and that its support force is 4 699.76 kN. The support force changes relatively smoothly. It proves that the lattice energy-absorbing device with the pyramid structure has superior energy absorption and can improve the safety of the anti-impact hydraulic support.
