摘要

传统的榫眼连接加工效率低，理论基础薄弱，使结构容易变形和损坏，降低了安全性，增加了资源浪费。本研究旨在确定倒角连接构件的最佳榫心间距参数，以及节点的抗折强度和抗拉强度的最大值。本研究采用单因素检验和单因素方差分析相结合的综合优化方法，研究木榫中心间距对柏木倒角接头构件抗弯强度和抗拉强度的影响。结果表明:倒角连接构件的抗弯强度随榫芯间距的增大呈线性降低;倒角接头构件的抗拉强度随销钉中心间距的增大先增大后减小，呈抛物线变化;得到了销钉中心间距与抗弯强度、销钉中心间距与抗拉强度之间的关系式。

Influence of Dowel Center Spacing on Chamfered-Joint Components Made by Cupressus funebris Wood

The traditional tenon and mortise joint has low processing efficiency and a weak theoretical basis, making the structure easy to deform and damage, reducing the safety, and increasing waste of resources. This study aims to determine the optimum dowel center spacing parameter for chamfered-joint components and the maximum value of the strength of joints loaded into bending strength and tensile strength. In this study, an integrated optimization method combining the single-factor test and one-way ANOVA analysis was proposed to study the influence of the dowel center spacing on the bending strength and the tensile strength of chamfered-joint components made by Cupressus funebris wood. The results revealed that the bending strength of chamfered-joint components decreases linearly with the increase of the dowel center spacing. In addition, the tensile strength of chamferedjoint components increases first and then decreases with the increase of the dowel center spacing, showing parabola change. The relational expression between dowel center spacing, the bending strength, dowel center spacing and the tensile strength were obtained.

期刊介绍： This journal publishes high quality peer reviewed original research and review articles on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. JRM showcases both fundamental aspects and applications of renewable materials. The fundamental topics include the synthesis and polymerization of biobased monomers and macromonomers, the chemical modification of natural polymers, as well as the characterization, structure-property relationships, processing, recycling, bio and environmental degradation and life cycle analysis of the ensuing materials, in view of their potential applications. Within this sustainability approach, green chemistry processes and studies falling within biorefinery contexts are strongly favored.
