“…designed a composite EAS for a certain subway vehicle to meet the requirements for passive safety protection during railway vehicle collisions. Peng et al (2015) presented a composite EAS mainly composed of a square tube and aluminium honeycomb structure for use in subway vehicles and discussed its collision performance: they found that a structural form that can induce more regular folding buckling will promote the energy absorption and crashworthiness of a structure.…”

“…In recent decades, composite structures [13][14][15][16] develop quickly and have been investigated in researches [17][18][19][20][21][22][23] and used in various kinds of structures [24][25][26][27][28][29][30][31][32] and infrastructures [33][34][35][36][37][38][39][40][41][42]. e steel truss CB is a special kind of steel CB that satisfies flexible layout, clear loading path, and adaptable architectural features; however, investigations on steel truss CB shear wall structures are scarce.…”

Based on existing experimental results, the finite element analyses were carried out on shear wall structures with steel truss coupling beams. is work studied the seismic behaviors and the working mechanism of the steel truss coupling beam at the ultimate state and put forward two parameters: the area ratio of web member to chord and the stiffness ratio of coupling beam to shear wall. e seismic optimum design method of the coupling beam was also proposed. Afterwards, a comparative analysis was implemented on the three-dimensional shear wall model with steel truss coupling beams designed by the proposed design method.e results show that the structures designed by the proposed method have excellent seismic behaviors, the steel truss coupling beams have enough stiffness to connect shear walls effectively, and its web members have appropriate cross sections to dissipate seismic energy.

“…J. Marzbanrad et al [8] investigated the crashworthiness of aluminum hollow tubes for vehicles, and the crash load for a single tube was 15 kN. Y. Peng et al [9] showed a composite energy-absorbing structure whose average crashing force was around 500 kN for subway vehicles. S.C. Xie et al [10] presented a front-end energy-absorbing structure for railway vehicles, whose crushing force could reach over 2,000 kN.…”

Abstract. In this paper, we carried out a structural optimization of an railcar coupler energy absorbing device. we established a finite element (FE) model and validated it by experimental results. We used a central composite design (CCD) and Hammersley design of experiments (DOE) to take samples for the variables. Based on these samples, we built an approximation model with the moving least squares method (MLAM). The maximum error percentage of the model was 2.30%. The main effect analysis indicated that the thickness T had the more significant effect on the average mean force (Favg) and the specific energy absorption (SEA). Considering the average mean force, fracture and buckling of the structure as constraints, we carried out parameter optimization using the global response surface method (GRSM) to gain a higher SEA. Finally, we obtained the optimum parameters (T = 7.72 mm, ɑ = 29.34º) with the SEA value of 35.28 kJ/kg. The value of SEA increased by 56.18%.
