The objective of the paper is to design a trailer structure that can carry a payload of 15 tons. This payload capacity suggests that the trailer is intended for heavy-duty transportation. It emphasizes the need for innovative solutions to reduce the weight of trailer structures, ultimately leading to lower fuel consumption and emissions. The transportation industry's commitment to sustainable practices and the adoption of advanced materials are crucial steps toward achieving environmental goals and creating a greener future. The use of advanced light-weight materials is a key aspect and include high-strength alloys, composites, or other innovative materials, have a higher strength-to-weight ratio compared to traditional materials. By using advanced lightweight materials, designing efficiently, and analyzing the structure's performance, actively contributing to reduced fuel consumption, lower emissions, and a greener future. In the present work, an advanced lightweight material, AlBeMet AM162 Extruded Bar was selected, and the structure has been designed and analyzed for weight reduction. The trailer structure has been modeled in ANSYS and significant reduction has been observed in the weight of trailer structure which leads to decrease in consumption of fuel with an appreciable reduction in CO2 emission preventing the environment from pollution. By reducing the weight of the trailer structure, the overall load on the towing vehicle is diminished. This leads to improved fuel efficiency and decrease in vehicular emissions.
