带波纹盖板的高效螺栓连接抗滑移系数影响因素试验研究
Experimental Study on the Factors Affecting the Anti-slip Coefficient of Efficient Bolted Connections with Corrugated Cover Plates
摘要
Abstract
In order to improve the connection efficiency of slip-critical high-strength bolt connections,an efficient bolt connection form by combining hard metal corrugated plate with soft metal is proposed,which can significantly improve the anti-slip coefficient of bolted connection through the furrow effect and adhesion effect between contact surfaces.Using a combination of theoretical and experimental research methods,the mechanism and influencing factors of efficient bolted connection form were clarified.A total of 27 anti-slip coefficient tests and 4 surface hardness tests were designed and carried out to investigate the influence of different surface treatments and hole types on the anti-slip coefficient of bolted connection,and the results were compared with the theoretical analysis results.The test results show that the hardness ratio of hard metal and soft metal is an important factor affecting the anti-slip coefficient and the use of non-standard holes will reduce the anti-slip coefficient.The proposed efficient connection form can achieve an anti-slip coefficient value of up to 0.89,which can significantly improve the anti-slip coefficient of high-strength friction-type bolt connection,and greatly improve the efficiency of the connection of individual bolts.关键词
