摘要

摘要: 随着我国内河航道桥梁建设规模扩大，船舶撞击导致的桥墩安全事故频发，蜂窝结构凭借轻质高强、吸能效率高的优势，成为桥梁防撞领域的潜在替代方案。但传统正六边形直蜂窝存在共面性能薄弱的缺陷，船舶斜撞时需额外导向机构，现有折纸蜂窝虽能提升共面强度，却常以牺牲异面强度为代价，难以兼顾实际防撞需求。为此，基于中面偏移法聚焦折纸型蜂窝结构，构建参数化建模体系，区分A、B、C三类构型，明确其三维形态由五类核心参数决定，并重点探究关键参数对结构性能的影响规律。通过有限元仿真对比折纸蜂窝与传统直蜂窝的共、异面抗压性能，同时针对性能较优的构型深入分析参数变化对其力学性能的作用机制。研究发现：B型折纸蜂窝能有效兼顾 “削峰” 与耗能需求，综合性能最优，且特定参数组合可实现结构性能与经济性的平衡。该研究为折纸蜂窝在桥梁防撞领域的参数优化与工程应用提供关键选型依据，对提升内河桥梁桥墩防撞安全性具有重要实践价值。

Abstract: As China’s inland waterway bridge construction grows， ship collisions frequently damage piers. Honeycomb structures—lightweight， high-strength， and effective at absorbing energy—are promising for pier collision protection. However， traditional straight hexagonal honeycombs have weak in-plane performance and require additional guides for oblique ship impacts； while existing origami honeycombs enhance in-plane strength， they lack out-of-plane strength， failing to meet practical needs. This study used the mid-plane offset method to develop a parametric modeling framework for origami honeycombs. The framework classified the structures into three types （A， B， and C）， defined their three-dimensional morphologies as being governed by five core parameters， and investigated the influence of key parameters on structural performance. Finite element simulations were conducted to compare the in-plane and out-of-plane compressive performance between origami honeycombs and traditional straight honeycombs. A detailed analysis of the parameter influence on mechanical properties was further performed for the superior configuration. The results indicated that Type B origami honeycomb offers the optimal overall performance by effectively balancing “peak force reduction” and energy absorption requirements. Moreover， specific parameter combinations were identified to achieve a balance between structural performance and cost-effectiveness. This research provides a critical reference for parameter optimization and engineering application of origami honeycombs in the field of bridge collision protection， holding significant practical value for enhancing the safety of inland waterway bridge piers against ship impacts.
