摘　　要：下文对新型不锈钢端板攻丝连接与传统高强度螺栓连接抗拉受力性能进行试验对比,并对不锈钢端板攻丝连接进行有限元分析,研究其破坏形态、受力机理和极限承载能力。分析结果表明:随着攻丝端板板厚的增加,连接件破坏形态由攻丝端板破坏转向螺栓第一排螺纹处拉断破坏,揭示了新型不锈钢端板攻丝连接形式的破坏机理,且攻丝连接件极限承载力达到了传统连接理论值,表明连接件的可靠。In this paper,the tensile and mechanical properties of the new stainless steel end plate tapping connection are compared with the traditional high-strength bolted connection,and the finite element analysis of the stainless steel end plate tapping connection is carried out to study its failure mode,force mechanism and ultimate bearing capacity.The analysis results show that with the increase of the thickness of the tapping end plate,the failure mode of the connector changes from the failure of the tapping end plate to the breakage failure at the first row of threads of the bolt,which reveals the failure mechanism of the new stainless steel end plate tapping connection form,and the ultimate bearing capacity of the tapping connector reaches the theoretical value of the traditional connection,indicating the reliability of the connector.
