Abstract

a presente invenção refere-se a um processo para determinar os parâmetros estruturais de uma via férrea, que compreende um conjunto de sensores. o processo compreende medir pelo menos as irregularidades verticais e/ou laterais do dito trilho com o conjunto de sensores ao longo do trilho, desse modo, proporcionando os sinais correspondentes às irregularidades geométricas, a diferentes distâncias da roda - carga. um modelo é proporcionado, que descreve a forma de deflexão de um trilho, em que a forma de deflexão é dependente dos parâmetros estruturais do trilho e das cargas nele, o dito modelo sendo armazenado no processador. no processador, as ditas irregularidades geométricas são comparadas, sob diferentes influências de cargas, para gerar uma forma de deflexão medida. pelo uma forma de deflexão do trilho teórica é gerada por uso do modelo, por variação dos parâmetros estruturais e da carga no dito modelo. pelo uma das ditas formas de deflexão teóricas é comparada com a dita forma de deflexão medida, para cada ponto do trilho, e os parâmetros estruturais dessa forma de deflexão teórica, que melhor se ajustam à dita forma de deflexão medida, são determinados. um aparelho configurado para executar o processo é também proporcionado.
