摘要

为了研究木质缠绕圆管在不同缠绕角度（从 0 度到 90 度，每隔 15 度）下的抗压行为，我们设计了 28 个试样进行实验研究。结果发现，试样的破坏模式与缠绕角有关：标注为 WD0 和 WD15 的试样表现为脆性断裂，标注为 WD45 至 WD90 的试样表现为渐进式破碎，其余试样则表现为混合破坏。结果表明，随着卷绕角的增加，抗压强度逐渐降低。此外，比能量吸收（SEA）、平均压碎力（MCF）和压碎力效率（CFE）随卷绕角的增大而增大，而峰值压碎力（PCF）则先减小后增大。此外，还提出了一个基于正弦和三次函数的经验公式，用于预测不同缠绕角度下木质缠绕圆管的抗压强度。此外，还引入了理论公式来预测平均压碎力。

Compressive behavior of wood winding circular tubes at different winding angles

In order to study the compressive behavior of wood winding circular tubes at different winding angles (from 0 degrees to 90 degrees, with intervals of every 15 degrees), 28 specimens were designed for experimental research. The failure modes of the specimens were found to be dependent on the winding angle: specimens labeled WD0 and WD15 exhibited brittle fracture, specimens labeled WD45 to WD90 showed progressive crushing, and the remaining specimens experienced mixed failure. The results indicated that the compressive strength gradually decreased with the increase of winding angle. Additionally, specific energy absorption (SEA), mean crushing force (MCF) and crush force efficiency (CFE) increased with the winding angle, while peak crushing force (PCF) initially decreased and then increased. Further, an empirical equation based on a sine and cubic function was proposed to predict the compressive strength of wood winding circular tubes at different winding angles. Theoretical formulas were also introduced to predict the mean crushing force.

期刊介绍： European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets. European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
