Abstract

PARA CONTROLAR UNA MAQUINA APISONADORA QUE TIENE UN RODILLO VIBRANTE (7) MIENTRAS COMPACTA EL MATERIAL DEL TERRENO, LA APISONADORA SE MUEVE SOBRE UN SEGMENTO DEL TERRENO MIENTRAS QUE EL COEFICIENTE DE CIZALLADO (G) Y UN PARAMETRO PLASTICO (P) DEL SEGMENTO PASADO SON DETERMINADOS. A PARTIR DE LOS VALORES OBTENIDOS, EN CONCRETO A PARTIR DEL VALOR DEL COEFICIENTE DE CIZALLADURA (G), SE DETERMINAN LOS NUEVOS VALORES DE LA FRECUENCIA Y/O DE LA AMPLITUD DE LA VIBRACION Y/O DE LA VELOCIDAD DE APISONADO DE LA APISONADORA, QUE SE UTILIZAN PARA AJUSTAR LA APISONADORA. EN LA MEDICION DEL COEFICIENTE DE CIZALLADURA, SE UTILIZAN DOS ACELEROMETROS (3, 5) PARA DETERMINAR, DURANTE LA PASADA DE UN SEGMENTO DEL TERRENO, LA ACELARACION DEL TAMBOR APISONADOR (7) EN AL MENOS UNA DIRECCION ESENCIALMENTE VERTICAL. LA AMPLITUD Y LA POSICION DE LA FASE DEL SISTEMA EXCENTRICO EN RELACION CON LA ACELERACION, SE DETERMINAN UTILIZANDO , ENTRE OTRAS COSAS, UN SENSOR DE PULSOS (2). A PARTIR DE ELLO Y DE DATOS FIJOS DE LAAPISONADORA Y DEL SISTEMA EXCENTRICO, EN CONCRETO LA MASA (M{SUB,D}) DE LA APISONADORA Y LA MASA Y LA AMPLITUD DEL SISTEMA EXCENTRICO, EL COEFICENTE DE CIZALLADURA (G) DEL TERRENO SE DETERMINA MEDIANTE LA INTEGRACION DE ECUACIONES DE ESTADO. A CONTINUACION SE OBTIENE TAMBIEN EL PARAMETRO PLASTICO (P).
