Mechanical Problems of Faired Tricycles: Investigation of Features Using Smartphones (Low Consumption Electrical Vehicles Eco Marathon)

Abstract: The choices involved in designing a road-ready streamlined electric recumbent bicycle are numerous (tyres, suspension, centre of gravity, brakes, lighting, etc.). The fairing offers protection from poor weather conditions and improves the aerodynamics but increases the mass by 20 kg. This weight of the fuselage and an average speed of 50 km/h requires motorization. The vehicle’s range is defined by the energy required by a given motor as a function of road grades and average speed. Vehicle performance profiling requires instrumentation and recordings that can be achieved with a simple smartphone (lux meter, deceleration brakes, acceleration suspension, GPS and power, acoustic noise). The mechanical and electrical characterization is presented in this article with the aim of identifying the limits and possibilities of the vehicle. This article demonstrates that the realization of a low-energy vehicle is an excellent teaching tool that can be reintroduced into everyday life on any vehicle.
