Resumo
O transporte de pessoas em ambulâncias nunca foi um bem desejável a ninguém, ainda mais sabendo que esse tipo de veículo pode também ser um dos motivos do número de mortes, incapacidades físicas e psicológicas que o transporte pode causar. Isso porque, não há modificações concisas no projeto de um veículo ambulância em relação a um furgão para carregamento de cargas. Pensando nisso, surgiu o Smooth Saving, que oferece um maior conforto para os pacientes, além de proporcionar também melhores condições de trabalho aos profissionais de saúde durante o trajeto. Isso pelo fato de que o objetivo deste trabalho é atenuar vibrações decorrentes aos declives provindos do solo e transferido ao veículo. Dessa forma, o foco para a solução empregada foi modificar o sistema de suspensão do veículo, alterando de uma suspensão convencional para sistema de suspensão com controle ativo utilizando amortecedores magneto reológicos. Obviamente só com essa modificação, não seria atingido a melhoria, já que para que esse novo sistema de suspensão tenha sua efetividade, foi necessário a mudança de outros componentes como adicionar acelerômetros, sensores de níveis, drivers de potência, ECU programável e ainda buscar um sistema de molas dimensionadas. Sendo assim, através de estudo de caso verificou-se que o comparativo entre as suspensões convencionais e suspensões ativas poderia aumentar o conforto de no mínimo 22%. Partindo deste número foi possível viabilizar a causa para implementação em veículos de ambulâncias, quando necessário de acordo com a sua aplicação. Para a validação do projeto, usou-se o modelo SkyHook controlado através da lógica Fuzzy, que utiliza de um processo de gerenciamento de dados para a escolha do coeficiente de amortecimento 𝐶𝑠𝑘𝑦. Após foi validado através de simulações na ferramenta interna do Matlab, o Simulink atigindo um ganho de 56% nas condições impostas pelo projeto.
Transporting people in ambulances has never been a desirable actto anyone, especially knowing that this type of vehicle can also be one of the reasons for the number of deaths, physical and psychological disabilities that transport can cause. This is because, there are no concise modifications in the design of an ambulance vehicle in relation to a van for loading loads. Thinking like that, Smooth Saving was created, offering greater comfort for patients, as well as providing better working conditions for health professionals during the journey. The objective of this work is to attenuate vibrations resulting from the slopes coming from the soil and transferred to the vehicle. Thus, the focus for the solution employed was to modify the vehicle's suspension system, changing from a conventional suspension to a suspension system with active control using magnetorheologicalshocks. Obviously, only with this modification, improvement would not be achieved, since in order for this new suspension system to be effective, it was necessary to change other components such as adding accelerometers, level sensors, power drivers, programmable ECU and even looking for a dimensioned spring system. Thus, through a case study it was found that the comparison between conventional suspensions and active suspensions could increase comfort by at least 22%. Based on this number, it was possible to make the cause feasible for implementation in ambulance vehicles, when necessary according to their application. For the validation of the project, the SkyHook model was controlled using the Fuzzy logic, which uses a data management process to choose the𝐶𝑠𝑘𝑦damping coefficient. After it was validated through simulations in the Matlab internal tool, Simulink achieving a gain of 56% in the conditions imposed by the project.
