STUDIES OF BOLTED FRICTIONAL-SLIPPAGE CONNECTION: Part1 Experiments of frictional-slippage connection using aluminum alloy sliding plates

In this paper, dynamic loading tests were conducted using the bolted frictional slippage connection specimens that sandwiched aluminum alloy sliding plates in order to investigate frictional slipping behavior such as the variation of slip coefficient while slipping and the influence of the initial bolt tension to the kinetic slip coefficient. As the result, specimens using high strength aluminum alloy sliding plates showed stable enough frictional slipping behavior rather than other two aluminum alloy sliding plates and the initial bolt tension had little influence on the slipping coefficient. In addition, in order to predict the slip coefficient of the specimen, a nonlinear regression equation was applied and its regression coefficients were obtained using nonlinear least squares fitting. This equitation predicted varying slip coefficient of specimens using high strength aluminum alloy approximately.
