Resumen
A melhoria da segurança operacional e da eficiência energética do transporte ferroviário de passageiros é um requisito importante para os operadores. Assim, avaliar a perda de energia é um fator crítico a ser estudado. Neste artigo é apresentada uma abordagem para determinar as perdas de energia dos diferentes componentes de um veículo de passageiros. Empregando modelagem de dinâmica multicorpos, um trecho medido de 33 km de uma ferrovia compartilhada de carga/passageiros no Brasil foi utilizado para determinar as principais fontes de dispêndio de energia durante a operação, que incluem o contato roda/trilho, a suspensão do veículo e os elementos de conexão entre veículos. Um vagão com truqueY32RS de bitola métrica com capacidade para 80 passageiros foi modelado. O estudo inclui tanto a dinâmica lateral como a longitudinal, levando em conta as irregularidades das vias. O consumo de energia por elemento foi analisado para determinar as perdas de eficiência no uso de combustível decorrentes das características de operação do veículo. Além disso, a metodologia proposta pode ser aplicada para otimizar outros parâmetros de veículos ferroviários visando a economia de energia.
The improvement of operational safety and energy efficiency in passenger rail are important requirements for railway operators. For this reason, analyzing the energy losses in the system is a critical factor. This article presents an approach to determine the energy losses in the different components of a passenger vehicle. Using multibody dynamics modeling, a 33 km section of a shared cargo/passenger railroad was utilized to determine the main sources of energy loss in operation. These sources include the wheel/rail contact, the vehicle suspension, and the connection devices between vehicles. A wagon equipped with Y32 RS, metric gauge, bogies with an 80-passenger capacity was modeled. The study includes both the lateral and longitudinal dynamics, while considering the track irregularities. The energy consumption per vehicle element was analyzed to determine the fuel efficiency losses during operation. Also, the proposed methodology could be used to optimize railway vehicle parameters in relation to energy savings.
