摘要

摘要: 针对工程中常见预紧力作用下的搭接接头,研究其在小幅切向位移激励时的切向位移响应问题,为此提出一种新的基于实际表面形貌和材料性能参数的滑移力密度分布函数.应用该分布函数得到搭接接头切向响应本构模型,并获得单位加载周期内的迟滞曲线和能量耗散值, 通过与已出版的实验结果相对比,发现得到的模拟值与实验结果吻合, 证明该模型的合理性.在此基础上利用该分布函数研究了接合面切向位移与切向力、切向接触刚度及能量耗散之间的关系,结果表明: 建立的模型能很好地描述接合面间切向力与切向位移之间的关系,临界滑移力函数开始迅速上升, 到达最大值后迅速收敛到零;切线力与切向位移之间表现出非线性特性, 随着切向位移的增大,切向接触刚度表现出"软化"现象;初始切向刚度与法向载荷、粗糙度参数及塑性指数有关, 对于确定的接触表面,法向力越大, 初始切向刚度越大; 初始切向刚度同样也随着塑性指数的增大而增大.

Abstract: Aiming at the problems of tangential displacement response of common used pre-tightening lap joints under tangential displacement excitation in engineering, a new slip force density distribution function based on actual morphological parameters and material performance parameters was proposed. The tangential response constitutive model of lap joint was obtained by using the distribution function, and the hysteresis curve and energy dissipation value per loading cycle were obtained. Compared with the published experimental results, it is found that the simulation value was consistent with the experimental, which proves the rationality of the model. Based on this, the relationship between the tangential displacement of the joint surface and the tangential force, tangential contact stiffness, and energy dissipation was studied. The results showed that the model could well describe the relationship between tangential force and tangential displacement. The trend of critical slip force function rise rapidly and then converges to zero after reaching its maximum value. The tangential force and tangential displacement show a non-linear characteristic, and with the increase of tangential displacement, the tangential contact stiffness shows softening phenomenon; the initial tangential stiffness is related to normal load, roughness parameters and plastic index. For a given contact surface, the greater normal force is given, the greater initial tangential stiffness is observed; the initial tangential stiffness also increases with the increase of plastic index.
