Abstract

LA INVENCION SE REFIERE A UN METODO PARA INVESTIGAR RUTAS DE RUIDO TRANSMITIDO POR ESTRUCTURAS EN UNA ESTRUCTURA COMPLEJA COMPUESTA DE AL MENOS DOS PARTES UNIDAS POR ELEMENTOS DE CONEXION, POR EJEMPLO AMORTIGUADORES O APOYOS ELASTICOS DE MOTOR O AISLADORES DE SUSPENSION, EN DONDE UNA DE ESTAS PARTES GENERA VIBRACIONES QUE CAUSAN RUIDOS. EL METODO COMPRENDE LOS SIGUIENTES PASOS: OMPRENDE UNA MASA INERCIAL ADICIONAL Y UN ACTUADOR EN UN PUNTO SITUADO EN LAS PROXIMIDADES DE UN ELEMENTO DE CONEXION (4) ENTRE DOS PARTES DE LA ESTRUCTURA, ESTANDO CONECTADO DICHO ACTUADOR (6) A UN CONTROLADOR (20); 8) PARA DETECTAR LA CANTIDAD DE VIBRACION CERCA DEL PUNTO EN EL QUE ESTA MONTADO EL DISPOSITIVO ACTUADOR (6) O EN EL PROPIO DISPOSITIVO ACTUADOR, ESTANDO CONECTADO(S) DICHO(S) SENSOR(ES) AL CONTROLADOR; RTE QUE GENERA VIBRACIONES; EXCITAR EL CONTROLADOR (20) DE ACUERDO CON UNA ESTRATEGIA DE CONTROL PREDETERMINADA TENIENDO EN CUENTA DICHA SEÑAL DE REFERENCIA; ON O RUIDO EN LUGARES PREDETERMINADOS DE LA ESTRUCTURA; ULAR LA INFLUENCIA DE LA FUERZA DE VIBRACION TRANSMITIDA POR EL ELEMENTO DE CONEXION (4) EN LOS VALORES MEDIDOS.
