Abstract

Polymer lattice structures, also known as polymeric cellular structures or polymeric foams, are widely used in various applications because of their unique properties, such as low density, high strength-to-weight ratio, and exceptional energy absorption. The objective of this work is to thoroughly examine the compression mechanical properties of strut-based truss constructions. As part of the study, these structures were created using an MSLA 3D printer, and both empirical and computational studies were conducted. Furthermore, the Taguchi method was employed for optimization purposes, and a thorough examination of statistical analyses was conducted. Lattice structures were developed using the SpaceClaim program and produced using the Ancubic M3 MSLA technology, which employs additive manufacturing. The LS-Dyna module of ANSYS Workbench was employed to create the finite element model of the lattice structures, and the manufactured specimens were subjected to compression experiments under the same conditions. The novelty of this work lies in generating MSLA 3D printer strut-based truss structures using both experimental and numerical analysis. Results show that increasing the cell counts also increases the compressive strength and absorbed energy. Similarly, struts and additional supports, which act synergistically, reduce stress concentration and improve stress distribution. Hence, compressive strength and absorbed energy increase. While structures consisting of pyramidical cells can be preferred in constructions where construction weight is not a limiting factor, it is preferable to use regular lattice structures in constructions where construction weight is a limiting factor.

基于支柱的优化设计提高晶格结构的力学性能
聚合物晶格结构,也被称为聚合物细胞结构或聚合物泡沫,由于其独特的性能,如低密度、高强度重量比和特殊的能量吸收,被广泛应用于各种应用。这项工作的目的是彻底检查基于支柱桁架结构的压缩力学性能。作为研究的一部分,这些结构是使用MSLA 3D打印机创建的,并进行了实证和计算研究。此外,采用田口法进行优化,并对统计分析进行了彻底的检查。点阵结构使用spacecclaim程序开发,并使用Ancubic M3 MSLA技术生产,该技术采用增材制造。利用ANSYS Workbench的LS-Dyna模块建立了网格结构的有限元模型,并在相同的条件下对制作的试件进行了压缩实验。这项工作的新颖之处在于使用实验和数值分析生成MSLA 3D打印机支柱桁架结构。结果表明,细胞数的增加也增加了材料的抗压强度和吸收能量。同样,支撑和附加支撑协同作用,减少应力集中,改善应力分布。因此,抗压强度和吸收能量增加。虽然在结构重量不是限制因素的情况下,由金字塔单元组成的结构是首选的,但在结构重量是限制因素的情况下,更可取的是使用规则的晶格结构。
