Abstract

a presente invenção refere-se a um método para operar uma usina mecânica (1) que tem um trem de eixos, com as etapas de: a) determinar, computacionalmente, a frequência harmônica de pelo menos um modo de vibração de torção do trem de eixos, e determinar, computacionalmente, as tensões mecânicas do trem de eixos, que se originam durante um período de vibração do modo de vibração de torção; b) determinar em cada caso uma correlação para cada modo de vibração de torção, entre uma primeira amplitude de tensão, que surge em uma posição do trem de eixos que apresenta um risco de formação de dano de tensão, e uma segunda amplitude de tensão, que surge em um local de medida (7 a 11) do trem de eixos, usando as tensões determinadas computacionalmente para o respectivo modo de vibração de torção; c) estabelecer uma primeira amplitude de tensão máxima; d) estabelecer, usando a correlação, uma segunda amplitude de tensão máxima, correspondente à primeira amplitude de tensão máxima, para o local de medida; e) medir, no local de medida e ao longo do tempo, a tensão do trem de eixos, enquanto este está girando; f) determinar, da tensão medida, uma amplitude de tensão em cada frequência harmônica; g) emitir um sinal no caso no qual, em uma das frequências harmônicas, a amplitude de tensão, determinada das tensões medidas, atingir a segunda amplitude de tensão máxima.
