Processo de desenvolvimento de suspensão para veículo elétrico de pequeno porte

Abstract

This work aimed to carry out a methodical analysis of the development process of products based on the Unified Reference Model to generate a project’s strategic plan to assist in the development of a vehicle suspension for AMR’s and AGV’s small size robots. Throughout the text it was discussed the influence and importance of technological development and automation in production lines, the history and evolution of the product development processes, construction of a roadmap referring to the model previously mentioned, furthermore the concepts and definitions of vehicle suspensions and springs with a focus on helical springs designed for dynamic loads were also discussed. From the planning management and organizational tools proposed, it was possible to design a suspension system with the intention of guaranteeing the vehicle’s wheels traction at all times, as well as its stability when carrying loads across a relatively flat and well-maintained factory floor. It was also carried out the dynamic energies’s dimensioning for the springs used in the project with the aim of guaranteeing their good functioning and resistance to fatigue resultant from the cyclic efforts applied to them.
