宋式二级燕尾榫特殊结构的力学性能分析
Analysis of Special Structure of Song-Style Second Grade Dovetail Tenon
摘要
Abstract
To better analyze the mechanical properties of the dovetail tenon structure,a twofold line multi-parametric mechanical structure was established,and a mechanical analysis test suitable for wood-en structures was carried out.Then,the corresponding dovetail joints were proposed based on the me-chanical balance and a deformation coordination relationship formula.The above research results show that the deformation of the dovetail tenon is mainly concentrated around the contact between the tenon and mouth.When the unidirectional load becomes larger,its bending moment also becomes larger,which is easy to cause damage to the contact surface.The load-displacement curve and the ultimate load-vertical load curve obtained through the test also show that when the vertical load increases,the ultimate load also increases;when the ultimate load reaches the yield critical point,the increase in displacement becomes smaller and tends to be smooth.关键词
