Title
(EN) METHOD FOR SUPPLYING VALUES OF PARAMETERS OF A HEAT SOURCE INTENDED TO CREATE A WELDED SEAM BETWEEN TWO PLATES, CORRESPONDING COMPUTER PROGRAM AND CORRESPONDING DEVICE
(FR) PROCEDE DE FOURNITURE DE VALEURS DE PARAMETRES D'UNE SOURCE DE CHALEUR DESTINEE A REALISER UN CORDON DE SOUDURE ENTRE DEUX PLAQUES, PROGRAMME D'ORDINATEUR ET DISPOSITIF CORRESPONDANTS
Abstract
(EN) This method comprises: - receipt of a desired value of at least one spatial characteristic (L1, L2) of the welded seam (202); - determination of several samples of the parameters of the heat source (104); - for each sample, determination of a value for each spatial characteristic (L1, L2) of the welded seam (202) for this sample; - several successive iterations of the following steps: the determination of points, referred to as extrapolated points, from simulated points, determination of a point, referred to as target point, of the function, at which each spatial characteristic (L1, L2) of the welded seam (202) exhibits a value close to the desired value, and determination of a value for each spatial characteristic (L1, L2) of the welded seam (202) from the values of the parameters of the heat source (104) for the target point, so as to obtain a new simulated point; and - the supply of the values of the parameters of the heat source (104) of the target point obtained in the last iteration.
(FR) Ce procédé comporte : - la réception d'une valeur souhaitée d'au moins une caractéristique spatiale (L1, L2) du cordon de soudure (202); - la détermination de plusieurs échantillons des paramètres de la source de chaleur (104); - pour chaque échantillon, la détermination d'une valeur de chaque caractéristique spatiale (L1, L2) du cordon de soudure (202) pour cet échantillon; - plusieurs itérations successives des étapes suivantes : la détermination de points, dits extrapolés, à partir de points simulés, la détermination d'un point, dit cible, de la fonction, où chaque caractéristique spatiale (L1, L2) du cordon de soudure (202) présente une valeur proche de la valeur souhaitée, et la détermination d'une valeur de chaque caractéristique spatiale (L1, L2) du cordon de soudure (202) à partir des valeurs des paramètres de la source de chaleur (104) pour le point cible, afin d'obtenir un nouveau point simulé; et - la fourniture des valeurs des paramètres de la source de chaleur (104) du point cible obtenu à la dernière itération.
