Abstract

LA INVENCION SE REFIERE A UN PROCESO DE MEDICION DE LA FORMA Y/O DE LA PLANITUD DE UNA FIBRA LONGITUDINAL DE UNA ANDA DE PASO. SE TOMAN ALTITUDES (YI) DE UN CONJUNTO DE N PUNTOS DE HILERA (I) DE DICHA FIBRA, Y SE DETERMINA UNA FUNCION (Y(I) DEPENDIENTE DE LA FORMA DE DICHA FIBRA. CUANDO SE TOMA LA ALTITUD DEL PUNTO DE HILERA (I), SE TOMAN SIMULTANEAMENTE LOS PUNTOS DE ALTITUD DE AL MENOS DOS OTROS PUNTOS QUE ESTAN CERCA Y SE SITUAN POR AMBAS PARTES DE ESTE. SE CALCULA APROXIMADAMENTE LA CURVATURA (K(X)I) DE DICHA FIBRA CERCA DE DICHO PUNTO DE HILERA I, Y DESPUES SE DETERMINAN UNA FUNCION (K(I)) REPRESENTATIVA DE LA EVOLUCION DE LA CURVATURA ENTRE DICHOS PUNTOS DE HILERA 1 Y DE HILERA N, Y POR INTEGRACIONES SUCESIVAS DE (K(I), SE DETERMINA UNA FUNCION (Y(I) REPRESENTATIVA DE LA FORMA PROPIA DE DICHA FIBRA ENTRE DICHOS PUNTOS DE HILERA 1 Y DE HILERA N, Y LA LONGITUD L DE DICHA FIBRA A PARTIR DE LA CAL SE CALCULA SU NIVEL DE ALARGAMIENTO. LA INVENCION SE REFIERE TAMBIEN A UN DISPOSITIVO PARA LA APLICACION DE ESTE PROCESO.
