On a new computational method for the simulation of periodic structures subjected to moving loads

Abstract: The purpose of the paper is to present a new numerical method suitable for the computation of periodic structures subjected to repeated moving loads. It directly derives from the stationary methods proposed for cylindrical and axisymmetrical structures. Its mains features are the use of a calculation reference related to the moving loads and the periodic property of the thermomechanical response. These methods are developped by PSA and the Ecole Polytechnique, in order to design vented brake discs. In this pap… Show more

“…An extrapolation technique, which significantly reduces the calculation time, has been developed by [14], if creep constitutes the damage criterion. To evaluate the stabilized cyclic behavior directly, the direct cyclic algorithm (DCA) was developed in [15]. DCA uses a combination of Fourier series and time integration of the nonlinear material behavior to obtain the stabilized response of a component iteratively [16].…”

“…Cependant, parmi les travaux numériques antérieurs (Lee et al, 1969 ;Altaweel et al, 1999 ;Floquet et al, 1996 ;Laraqi et al, 2001 ;Gao et al, 2002 ;Roussette et al, 2003 ;Nguyen et al, 2002Nguyen et al, , 2004Choi et al, 2004), rares sont les travaux qui tiennent compte du déplacement angulaire de la zone de frottement patin-disque, siège d'un flux de chaleur dissipatif variable ou discontinu. Parmi ces rares travaux, on peut citer ceux de Floquet et Dubourg (1996), qui ont développé un modèle numérique en vue de la simulation du comportement thermomécanique d'un disque de frein ventilé.…”
