Title (EN) METHOD AND SYSTEM FOR DETERMINING DEFORMATIONS BY MEANS OF AT LEAST TWO GAUGES
(FR) PROCEDE ET SYSTEME DE DETERMINATION DE DEFORMATIONS AU MOYEN D’AU MOINS DEUX JAUGES
Abstract: front page image
(EN)The invention relates to a method for determining the amplitude A of pseudo-sinusoidal deformations of a structural element area consisting in placing in said area at least two stress gauges (1) each of which produces a signal VI based on the deformation thereof, in forming at least two signals SI according to variations of at least one signal VI emitted by the gauges (1) during deformation, in forming two SIN and COS signals based on the signals SI for the same angle and the same A-dependent amplitude, and in calculating a SIN2 + COS2 expression in such a way that the amplitude A is derived therefrom. A system for determining by means of the inventive method is also disclosed.
(FR)L'invention concerne un procédé de détermination de l'amplitude A des déformations pseudo sinusoïdales d'une zone d'un élément structurel, ledit procédé prévoyant de disposer sur ladite zone au moins deux jauges (1) de contraintes, délivrant chacune un signal Vi fonction de la déformation subie par ladite jauge, de former au moins deux signaux Si qui sont fonction respectivement des variations d'au moins un signal Vi émis par les jauges (1) lors de la déformation, de former, à partir des signaux Si, deux signaux respectivement SIN et COS de même angle et de même amplitude, ladite amplitude étant fonction de A et de calculer l'expression SIN2 + COS2 de sorte à en déduire l'amplitude A. L'invention concerne également un système de détermination au moyen d'un tel procédé.
