Dedicated procedures for temporal identification in a flexible multi-body system

The aim of this paper is to evaluate forces and torques in flexible joints of a flexible multi-body system (FMS). To represent such a FMS a 2D non-linear model based on finite element method is built. Its numerical form solution based on a stable integration scheme and on the non-linear Newton-Raphson method is described. As the evaluation procedure first requires that some model physical properties are obtained as identified parameters, two procedures are used: direct and indirect identification. They are respectively based on dynamic equilibrium verification and on comparison between simulat...
