【摘要】 通过试验测试了6个相同试验件的承载能力,同时建立了有限元模型。同试验对比,验证建模方法正确后,用此模型研究了不同干涉配合对结构承载能力的影响。研究发现:承载能力随着干涉量的增加先增加后减小,对于所研究的连接构型,理想的干涉量在1.5%左右。更多还原

【Abstract】 Quasi-Static tensile to failure test of the 6 two-bolt single lap specimens were carried out to get the load capacity.The finite element model was created using ABAQUS software.After validated to be true through comparing with the test results,the finite element model was used to investigate the influence of more different interference fit conditions.The results showed that,the load capacity increase at first and then decrease as the interference fit grows.The ideal level of interference fit is about 1.5 percent for this specific structure.更多还原
