摘　　要：文章以重组竹为材料,将CreoSimulate有限元分析应用于圆榫的力学性能模拟、计算及参数优化。通过有限元分析对圆榫的抗扭强度进行参数优化,研究不同圆榫榫头间的宽度d1、圆榫直径D、插入长度l等参数对圆榫榫卯抗扭强度的影响。对优化后的圆榫结构进行疲劳分析得到:圆榫抗扭强度最优径长比c=2.4、径厚比d=0.4,容易疲劳损坏的部位为榫头以及榫头与榫眼相接触的区域。方法可为有限元数值模拟榫卯结构的建模以及圆榫的设计和制造提供参考。In this paper,the Creo simulate finite element analysis is applied to the simulation,calculation and parameter optimi⁃zation of the mechanical properties of the dowel with the rebamboo as the material.Through the finite element analysis,the torsional strength of the dowel is optimized.The effects of the width,diameter and insertion length between different tenons on the torsional strength of the tenon are studied,and the fatigue analysis of the optimized tenon structure is carried out.It is obtained that the ratio of diameter to length c=2.4 and the ratio of diameter to thickness d=0.4 when the torsional strength of the dowel is optimal,and the parts prone to fatigue damage are the tenon and the area where the tenon contacts the mortise.The method can provide a reference for the fi⁃nite element numerical simulation of mortise and tenon structure modeling and the design and manufacture of circular tenons.
