Resumo
Veículos são um dos principais meios de transporte no Brasil e no mundo, com uma frota que cresce ano a ano e que apresenta soluções cada vez mais avançadas para os diversos componentes e sistemas que compõe um veículo convencional. Dentre esses sistemas, temos como exemplo o sistema de freios, composto por alguns dos principais componentes responsáveis pela segurança dos ocupantes. Todavia, observa-se que na maioria dos casos possuímos um plano de manutenção estático para esses componentes, geralmente medido por quilometragem, que é definido previamente pelas montadoras. Nesse sentido, uma das preocupações é de que as condições que um veículo será submetido ao longo de sua utilização pode fugir do que foi estipulado para o plano de manutenção, encontrando, por exemplo, diferentes condições de terreno, clima, carregamento, perfil de condução, entre outros. Com isso em mente, este trabalho tem como objetivo realizar a previsão da taxa de desgaste (milímetros cúbicos por quilometro [mm³/km]) do material de atrito do sistema de freio. Foi feita uma fundamentação teórica, apresentando os principais conceitos na engenharia que podem ser empegados a fim de chegar a um modelo de monitoramento do desgaste das pastilhas de freio e fornecendo informações e dados ao motorista através de uma interface conforme seu modo de condução e condições que o veículo estará sujeito, fornecendo dados em tempo real que irão guiar o usuário para realizar a manutenção deste sistema no período correto. Previsão esta que foi desenvolvida durante este estudo através de testes realizados em uma bancada de freios para aquisição de dados e através do uso de softwares de computação numérica e análise de dados, os quais possibilitaram obter um método de predição de desgaste do material de atrito. Com o método desenvolvido foi possível então propor um sistema composto de uma central eletrônica de monitoramento e predição de manutenção e uma adaptação em uma pinça de freio genérica para que o método desenvolvido seja introduzido ao mercado automotivo.
Vehicles are one of the main means of transport in the world, with a fleet that grows year after year and presents increasingly advanced solutions for the various components and systems that make up a conventional vehicle. Among these systems, we have as an example the braking system, made up of some of the main components responsible for occupant safety. However, it is observed that in most cases we have a static maintenance plan for these components, generally measured by mileage, which is defined during the vehicle development by the car manufacturers. On this topic, one of the concerns is that the conditions that a vehicle will be subjected to throughout its use may deviate from what was stipulated for the maintenance plan, encountering, for example, different conditions of terrain, climate, loading, driving profile, between others. This work aims to predict the wear rate (cubic millimeters per kilometer [mm³/km]) of the brake system's friction material. A theoretical foundation was made, presenting the main engineering concepts that can be used to reach a model for monitoring brake pad wear and providing information and data to the driver through an interface according to their driving style and conditions that the vehicle will be subject, providing real-time data that will guide the user to carry out maintenance of this system in the correct period. This prediction was developed during this study through tests carried out on a brake bench for data acquisition and using numerical computing and data analysis software, which made it possible to obtain a method for predicting wear of the friction material. With the method developed, it was then possible to propose a system composed of an electronic maintenance monitoring and prediction center and an adaptation to a generic brake caliper so that the developed method could be introduced to the automotive market.
