摘要:

针对目前关于铝合金盘式节点的几何参数影响因素研究较少的现状,参照试验试件PS1并结合通用有限元软件ABAQUS建立几何参数模型,分析几何参数对盘式节点整体刚度与变形性能的影响。结果表明:当铝合金盘式节点的节点盘厚度增加时,节点的抗弯承载力有所提高,但提高幅度较小,整体初始刚度的变化不明显; 截面高度增加时,节点抗弯承载力及整体初始刚度近似呈线性提高,提高较为明显; 箱型腹板厚度增加时,节点抗弯承载力及箱型杆件在节点处的初始刚度有所提高,工型杆件在节点处的初始刚度降低幅度较小; 工型腹板厚度增加时,节点抗弯承载力及工型杆件在节点处的初始刚度有提高的趋势,箱型杆件在节点处的初始刚度基本呈线性降低; 箱型翼缘厚度增加时,节点的抗弯承载力及箱型杆件在节点处的初始刚度提高较为明显,但对工型杆件在节点处的初始刚度影响较小; 工型翼缘厚度增加时,节点的抗弯承载力及箱型杆件在节点处的初始刚度提高幅度有所增加,工型杆件在节点处的初始刚度近似呈线性提高。

Abstract:

Aiming at the status that the research on geometric parameters influence factor of aluminum alloy TEMCOR joints was less, a geometric parameter model was established based on the test piece PS1 and the general finite element software ABAQUS, and the influences of geometric parameters on the overall stiffness and deformation performance of disc joints were analyzed. The results show that when the plate thickness of aluminum alloy TEMCOR increases, the flexural capacity increases with small amplitude and the overall initial stiffness is not obvious; when the section height increases, the flexural capacity and initial stiffness of joints increase linearly and improve more obvious; when the thickness of the box web increases, the flexural capacity and initial stiffness of joints increase with large amplitude; the initial stiffness of the limb type member decreases slightly; when the thickness of I-shaped web increases, the flexural capacity of the joint and the initial stiffness of the limb shaped member are improved; the initial stiffness of the box member is linearly reduced; when the thickness of the box flange increases, the flexural capacity of the joint and the initial stiffness of the box member are improved obviously, but the initial stiffness of the limb type member is less affected; when the thickness of I-shaped flange increases, the flexural capacity of the joint and the initial stiffness of the box member are improved; the initial stiffness of the limb type member is linearly increased.
