Evaluation of the applicability of the lugre model for modelling the dynamic behaviourofbolt connected frames

Abstract

In this paper the dynamics of a frame with bolted connections is studied both theoretically and experimentally. The connections are described using the Lund-Grenoble(LuGre) model. The problem of the dynamic response of the frame to a pulse load is studied using the Galerkin approach that reduces the governing equations to a set of nonlinear ODE's. They are latter solved numerically. It is shown that the theoretical predictions match the experimental observations well.
