摘要
Abstract
The transverse impact characteristics of a flexible rubber pipe joint are studied. A pair of joints assembled end-to-end with an inserted middle mass was tested in a drop shock testing machine. Based on the test results, an equivalent beam model with fixed-ends and polynomial varying stiffness and damping was applied to predict the transverse impact response and identify the nonlinear impact parameters. The least square residual between the computed and tested results was chosen as the target to perform the identification optimization. The results show that the equivalent bending stiffness of the flexible rubber pipe joint gradually decreases with the increasing of the transverse deformation and is greatly influenced by its internal working pressure.关键词
