O livro Investigation of Lateral Vibrations in Turbine-Generator Unit 5 of the Inga 2 Hydroelectric Power Plant analisa as vibrações laterais de um sistema essencial para a produção de eletricidade na República Democrática do Congo. O estudo, baseado em medições efectuadas com doze sensores e sondas, revela que as vibrações das chumaceiras de guia e do rotor excedem os limites aceitáveis a velocidades de 100 a 250 rpm. Estes excessos podem provocar desequilÃbrios de massa, excentricidade do eixo e deformações dos veios de acoplamento. Efectuada em condições estáticas e dinâmicas, a análise revela desvios significativos em relação à s normas internacionais, alertando para problemas crÃticos. O artigo conclui sobre a urgência de intervenções, em particular o realinhamento de componentes, para garantir o desempenho e a segurança da unidade, recomendando ainda a monitorização das flutuações de pressão e dos problemas térmicos associados.
