Abstract

ACELEROMETRO DE RELUCTANCIA VARIABLE. EL ACELEROMETRO (1) INCLUYE SUSTANCIALMENTE UN IMAN PERMANENTE (12) EL CUAL, EN POSICION DE REPOSO, SE MANTIENE DINAMICAMENTE EQUILIBRADO GRACIAS A LOS CAMPOS MAGNETICOS QUE ACTUAN SOBRE LADOS OPUESTOS RESPECTO A SUS POLOS, Y ESTA DISEÑADO PARA DESPLAZARSE A LO LARGO DE UNA GUIA CORRESPONDIENTE (7). EL ACELEROMETRO (1) INCLUYE UNA BOBINA (8) DISPUESTA COAXIALMENTE RESPECTO A LA DIRECCION DEL IMAN (12) Y DISEÑADA PARA GENERAR UNA FUERZA ELECTROMOTRIZ CUYA INTENSIDAD DEPENDE DE LA ACELERACION RELATIVA DE LA BOBINA (8) CON RESPECTO AL IMAN (12) Y EN LA DIRECCION DE DESPLAZAMIENTO DEL MISMO.SE HA PREVISTO IGUALMENTE UN DISPOSITIVO DE PROCESADO ELECTRONICO (21, 22) PARA EL TRATAMIENTO DE LA FUERZA ELECTROMOTRIZ MENCIONADA Y PARA CONTROLAR UN DISPOSITIVO DE SEÑALIZACION (10) Y/O UNOS DISPOSITIVOS DE ACCIONAMIENTO APROPIADOS.EL ACELEROMETRO ES UTIL PARA MEDIR LA ACELERACION VERTICAL DE UN PUNTO DE UN SISTEMA EN MOVIMIENTO TAL COMO UN VEHICULO.
