Abstract

EN DISPOSITIVOS CONOCIDOS PARA LA PRUEBA DE ABSORBEDORES DE IMPACTO DE VEHICULOS, LOS NEUMATICOS, QUE DISPONEN DE UN EFECTO DE AMORTIGUACION, NO SON TENIDOS EN CONSIDERACION SINO QUE LOS RESULTADOS DE MEDICION PUEDEN SER FALSIFICADOS EN UNA CANTIDAD DE APROXIMADAMENTE EL 30 %, DEPENDIENDO DE LA PRESION DEL NEUMATICO. ADICIONALMENTE, CUANDO LAS RUEDAS ESTAN MONTADAS SOBRE EL VEHICULO, NO PUEDEN SER MEDIDAS LAS CUEVAS CARACTERISTICAS ABSORBEDORAS DE CHOQUE, SOLO CON VALORES INDIVIDUALES. EN EL DISPOSITIVO DESCRITO, SE ELIMINAN EL EFECTO DE NEUMATICO VARIABLE DE ACTUACION MEDIANTE UN PROCESO DE REGULACION QUE CONSISTE EN LA NORMALIZACION DE LA AMPLITUD DE RESONANCIA, OBTENIENDOSE UNA MEDICION CONSIDERABLEMENTE MAS PRECISA. ADICIONALMENTE LA CONSTANTE DE RESORTE DE LA SUSPENSION DE RUEDA SE DETERMINA ANTES DE LA ACTUALIZACION DE LA PRUEBA DEL ABSORBEDOR DE CHOQUES, PERMITIENDO QUE SEAN DETECTADOS LOS RESORTES DEFECTUOSOS. FINALMENTE PUEDEN SER DETERMINADAS TAMBIEN LAS OSCILACIONES DEL CUERPO DEL VEHICULO, ORIGINANDO UNA GANANCIA DE PRECISION ADICIONAL. PARA EL PRIMER TIEMPO RESULTA POSIBLE LA DETERMINACION DE LA CURVA DE CARACTERISTICAS DEL ABSORBEDOR DE CHOQUES SIN TENER QUE DESMONTAR EL ABSORBEDOR DE CHOQUE.
