Compressive behavior and energy absorption of polymeric lattice structures made by additive manufacturing

Sheng WANG, Jun WANG, Yingjie XU, Weihong ZHANG, Jihong ZHU

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 2,   Pages 319-327 doi: 10.1007/s11465-019-0549-7

Abstract: Lattice structures have numerous outstanding characteristics, such as light weight, high strength, excellent shock resistance, and highly efficient heat dissipation. In this work, by combining experimental and numerical methods, we investigate the compressive behavior and energy absorption of lattices made through the stereolithography apparatus process. Four types of lattice structures are considered: (i) Uniform body-centered-cubic (U-BCC); (ii) graded body-centered-cubic (G-BCC); (iii) uniform body-centered-cubic with -axis reinforcement (U-BCCz); and (iv) graded body-centered-cubic with -axis reinforcement (G-BCCz). We conduct compressive tests on these four lattices and numerically simulate the compression process through the finite element method. Analysis results show that BCCz has higher modulus and strength than BCC. In addition, uniform lattices show better energy absorption capabilities at small compression distances, while graded lattices absorb more energy at large compression distances. The good correlation between the simulation results and the experimental phenomena demonstrates the validity and accuracy of the present investigation method.

Research of the effect of the component proportion in the new water mist additive to extinguishing performance

Ji Huanle,Zhang Qingsong,Wu Binbin,Liang Tianshui

Strategic Study of CAE 2012, Volume 14, Issue 11,   Pages 82-87

Abstract:

Water mist technology provides efficient firefighting performance while there is still room for improvement, so varieties of additives have been studied recent years both abroad and domestic. The self-made additives are used to compare the firefighting performance of diesel and heptane fire in open space. By adjusting the concentration of substance in the additives and conducting the experiment under the pressure of 0.3 MPa, 0.5 MPa and 0.7 MPa, extinguishing time, flame shape and temperature are measured in the experiment. Through the experiments using different fuels, it can be found when the fuel is heptane who has a lower ignition point and a higher evaporation, the water mist additives can still significantly improve the firefighting performance. According to the data based on different concentrations of fluorinated surfactants, we can see fluorinated surfactants are the main substance to prove the performances by changing physical property of water mist. Maximize fire performance proportion of the additives are find by experiments results.
