螺栓连接有限元模型的弹性接触研究OA北大核心CSCDCSTPCD
Research on Elastic Contact of Finite Element Model of Bolted Connection
采用刚性梁单元模拟螺栓连接结构来进行有限元分析不能准确计算螺栓连接区域的应力。根据真实螺栓连接结构的特点和连接原理,提出了基于弹性接触的螺栓连接模型,该模型引入GAP单元定义了被连接件之间的弹性接触与摩擦条件,并用实验验证了该方法的有效性。
Utilizing rigid--beam element to simulate the structure of culate the local stress of bolted connection. Therefore, an elastic contact ement was introduce to define the elastic contact and friction condition of posed according to the structure and characteristic of bolted connection. to verify the validity of the proposed method. bolted connection cannot cal- based bolted model (GAP el- bolted components) was pro Finally, a test was designed
