“…This is because the T6-treated alloys undergo artificial aging, a treatment that requires a higher energy expenditure. In this heat treatment, the alloys are solubilized and subsequently heated between 100 °C and 200 °C so that the atoms diffuse and precipitation of hardening phases could happen, optimizing the mechanical properties 7,9 . Therefore, this need for a prolonged heating of the parts may generate a higher energy spending than that associated with the production of alloys in T4 condition, which underwent only solubilization treatment, while the aging is carried out at room temperature (naturally).…”

“…Studies have been conducted with the aim of improving the autonomy of electric vehicles in order to make them competitive with vehicles powered through internal combustion. As a result, the efficiency of the electric motors, battery, transmission, the weight of each component, and even intelligent acceleration control profiles are being developed to obtain the best balance between autonomy and performance 3,6,7 .…”

The market for electric vehicles is growing, seen as the best alternative to replace internal combustion-powered vehicles. Recent developments in electric vehicles have allowed them to reach a level of performance, comfort, and safety that enables them to compete with traditional vehicles. However, several studies are directed towards increasing the autonomy of these vehicles, aiming at weight reduction of structural components. Aluminum alloys are increasingly being chosen to produce structural elements, due to their low density and suitable properties. The 6000 Al alloys are often used in chassis and bodywork. In view of this, this work proposes a comparison of 6000 series alloys, by means of thermodynamic (using Thermo-Calc®) and property computations (Ansys® Granta EduPack and Selector) to select the best alloys considering application properties, processability, and environmental impact. It was observed that the T6 heat-treated alloys presented better mechanical properties, but, on the other hand, they have more impact on the environment. As such, the 6010-T6 alloy was classified as the best alloy regarding performance, the 6061-T4 alloy the best in terms of processability, and the 6009-T4 alloy presented the lowest environmental impact. The 6111-T4 alloy was highlighted as the alloy showing the best balance between the examined properties.

“…The first step was to calculate the instantaneous power required to achieve the kinematic response for the vehicle being measured [38]. It is known that at each step during the test the tractive force shall be such that it counteracts total driving resistance and causes the vehicle to accelerate as required.…”

Cities are experiencing a process of suburbanization and last-mile delivery has grown, worsening traffic congestion, pollutant emissions, and citizens’ quality of life. Based on a real-life case study, this research compares the environmental performance of different delivery routes carried out by Diesel Light-Duty Vehicles (LDV) according to delivery area, city center or peri-urban. Some 242 delivery routes performed by thirteen drivers were recorded for one month, including instantaneous GPS position, speed, and other parameters (7262 km travelled). Four different delivery routes typologies were compared, and the drag function of the vehicles was characterized. It enabled calibration and modelling dynamics to calculate fuel consumption and pollutant emissions according to delivery routes. The results show that pedestrian crossings, traffic lights, and traffic congestion reduce the average operating speed by up to 57% in the city center and consequently overall energy efficiency. Our results highlight the urgency of replacing diesel LDV for deliveries in the city center with no-motorized transport modes and of implementing intermodality to cover deliveries in residential peri-urban areas. Due to low speeds and frequent start-stops, the efficiency of vehicles in these areas is reduced to a minimum and pollutant emissions increase. The outputs set a basis for recommendations for using LDV only for delivery routes with less traffic interruptions and foster intermodal solutions.

“…In the 2020 study of Sánchez and his colleagues, an iteration algorithm was proposed, during which a path and reference period were given to determine the chassis that best suited to electric vehicles. Thanks to the proposed methodology, battery weight was reduced by about 20% compared to normal designs [27]. In the 2020 study conducted by Nandhakumar and his friends, an electric motor-powered bus chassis design was made.…”

With technological developments and carbon emission reaching dangerous levels in the world, it is inevitable that electric vehicles will become the dominant transportation technology of the future. Studies on electric vehicles have become very popular today. In the automotive sector, sectoral dynamics and needs are rapidly changing; restrictions and demands are bound by strict rules and high value-added innovative studies are applied intensively. Supporting this area with academic data will contribute to research and development activities in this field. In this study, analysis and production studies were performed on a 3-wheeled vehicle chassis driven by electric energy. The chassis structure was designed and analyzed with details. The chassis aimed to be produced as a result of the study was analyzed in detail according to brake, modal and cornering analysis. As a result of these analyses, it was found that this chassis has a reliable structure according to the specified driving dynamics parameters. By adopting new requirements, technologies and analysis outputs for the system, a modular platform structure that can be used for various applications were created. The design and production processes of an innovative and applicable chassis structure for the electric vehicle ecosystem are given in detail.
