| 摘 要： | 为了很好的模拟带预紧力受剪螺栓的复杂应力状况,本文应用ANSYS非线性接触算法对螺栓连接进行了仿真,利用降温法模拟了螺栓的预紧力,给出了螺栓连接刚度计算公式,通过一系列不同厚度构件的螺栓连接刚度计算,得到了构件厚度与螺栓连接刚度间的关系曲线;为复杂结构中螺栓连接的简化计算提供了可靠参考依据.

| Abstract: | Nonlinear contact arithmetic of ANSYS is applied for simulating complex stress of sheared bolt with pre-tightened force and emulating bolt joint well. By cool method, pre-tightened force of bolt is caused. In this paper, we present a computational formula of bolt joint stiffness, and obtain relative curve between bolt joint stiffness and thickness of components by varying thickness of components. Reliable references are provided for simplified computation of bolt connection from complex structure. |
