Abstract

UN VIBRADOR TORSIONAL (1) COMPRENDE UN MOTOR DE CORRIENTE CONTINUA (2) PROVISTO DE BOBINADOS INDUCIDOS (7) ALIMENTADOS CON CORRIENTE CONTINUA A TRAVES DE UN MEDIO INVERSOR (10) CAPAZ DE CAMBIAR SU POLARIDAD DE FORMA ALTERNATIVA CON UNA FRECUENCIA PRESELECCIONADA. CON EL EJE (8) DEL MOTOR ELECTRICO (2) SE FORMA INTEGRALMENTE UNA RUEDA (13) QUE ESTA CONSTITUIDA POR UNA LLANTA (14) Y POR UN NEUMATICO (15) Y SE ASOCIAN TRANSDUCTORES DE ACELERACION (18, 19, 20, 21) CON LA LLANTA Y CON EL NEUMATICO DE LA RUEDA. EL EJE (8) DEL MOTOR (2) ES IMPULSADO PARA EJECUTAR OSCILACIONES ANGULARES (27) QUE EXCITAN TORSIONALMENTE LA RUEDA (13) Y PROVOCAN QUE VIBRE EN LA DIRECCION ROTACIONAL. LOS TRANSDUCTORES DE ACELERACION DETECTAN LAS VIBRACIONES ROTACIONALES Y SUMINISTRAN MEDIDAS DE LA ACELERACION DE LA LLANTA (14) Y DE LA RUEDA (15).
