带衬套沉头螺栓复合材料/金属接头拉伸性能
|
摘要
对带衬套沉头螺栓连接复合材料/金属接头进行拉伸试验,测量了接头的载荷-位移曲线和面外变形等性能,研究了接头的拉伸行为。利用ABAQUS软件,建立了接头的有限元模型,计算得到的条件挤压载荷、极限破坏载荷和破坏模式与试验结果吻合较好,证明了所建有限元模型的有效性。利用该模型,分析了接头破坏的机理,并进一步研究了螺栓与衬套过盈量、拧紧力矩和钛板厚度等因素对接头拉伸性能的影响。结果表明:适度的增大螺栓与衬套的过盈量能有效提高接头的刚度和强度;在一定范围内增加拧紧力矩能提高接头的承载能力;增加钛板的厚度,对接头的刚度有明显提升,但对极限破坏载荷影响较小。
The tensile test of the countersunk bolted composite material/metal joint with sleeve was carried out,load-displacement curve and out-of-plane deformation of the joint were measured,and the tensile behavior of the joint was analyzed. A finite element model of the joint was established by using ABAQUS software. The offset bearing load,ultimate load and failure mode calculated by finite element model were in good agreement with the experimental results,which proved the validity of the finite element model. Using this model,the mechanism of joint failure was analyzed,and the effects of bolt and sleeve interference,tightening torque and thickness of titanium plate on tensile performance of joints were further studied. The results show that moderately increasing the interference between the bolt and the sleeve can effectively improve the stiffness and strength of the joint; increasing the tightening torque within a certain range can increase the bearing capacity of the joint; increasing the thickness of the titanium plate can improve the rigidity of the joint obviously,but the impact on the ultimate breaking load is small.
