摘要：

对空心杆双锥构型点阵材料的压缩性能进行研究,对比了点阵材料与均质材料的压缩性能.点阵材料及均质材料的试件都采用多喷头光固化树脂增材制造技术制备,通过试验测试了均质材料件及 2 种元胞尺寸点阵材料件的压缩性能,获得了不同应变率载荷下的压缩应力-应变曲线,探索了元胞尺寸、加载应变率对材料压缩性能的影响,得到了材料破坏前的应力-应变关系预测表达式,应力预测结果与试验结果相吻合. 研究结果表明:点阵材料的元胞尺寸对材料压缩性能影响显著;不同应变率下点阵材料的屈服应变变化不大, 屈服强度差异相对较大;制备的点阵材料屈服应变大于均质材料屈服应变, 但屈服强度不具备优势.

Abstract:

The compression properties of the dual-pyramid lattice materials consisting of resin hollow tubes were studied and compared with those of the homogeneous materials. Specimens of lattice materials and homogeneous materials were fabricated using multi nozzle plastic additive manufacturing technology. The compression properties of homogeneous materials and lattice materials of two cellular sizes were tested. The compression stress-strain curves of different strain rates were obtained. The effects of geometry size of unit cell and strain rate were researched. The equations for predicting the stress-strain relations before material failures were obtained by fitting experimental data. The stress prediction results agree with the experimental results. The research results show that the cellular size significantly affects the compressive properties of lattice materials. The yield strain changed little under different strain rates, and the yield strength difference is relatively large. The yield strain of the presented lattice materials is greater than that of the homogeneous resin materials, and the yield strength is not greater than that of the homogeneous resin materials.

Key words: lattice material, dual-pyramid, compression properties, strain rate, additive manufacture
