“…These simulations serve as the foundation of our theoretical approach, allowing us to generate data that would otherwise necessitate extensive physical experimentation. To validate the model's adequacy, we cross-reference our simulation outcomes with existing scholarly literature and theoretical calculations [18]. A deviation of less than 5 % from these benchmarks is deemed acceptable [18,19].…”

This paper focuses on the design and evaluation of hollow frame structures for the development of two-passenger electric vehicles targeted for urban use. The primary problem addressed is the lack of focused research on efficient, lightweight, and safe electric vehicle frame designs, particularly for urban transportation needs. Through 3D simulation and Finite Element Analysis (FEA), this paper successfully develops a hollow frame design with dimensions of 2,148×800×640 mm and a weight of 40.77 kg that meets strength and stiffness criteria. The analysis shows that the design has an adequate safety margin with a safety factor of 2.053e+01. ASTM A36 steel is chosen as the material, balancing strength, stiffness, and cost. The results offer an innovative and practical solution to urban transportation issues, with broad potential applications in the electric vehicle industry. In particular, this study focuses on the specialized needs of urban-centric, two-passenger electric vehicles. The Finite Element Analysis (FEA) used here serves as a robust validation method, effectively reducing the need for extensive physical testing. This accelerates the R&D process and opens possibilities for future studies on alternative materials and dynamic loading conditions. The study's limitations and future research directions are also discussed. Moreover, the study's computational methods offer an eco-friendly alternative to traditional physical prototypes. This aligns with sustainability goals and provides methodologies for future studies. With rising urban populations, the demand for efficient vehicles is increasing. This study paves the way for city-focused, two-passenger electric cars that meet modern urban needs and sustainability goals

During car races, strong vibrations appear in the chassis of the vehicle, due to the high power created by the engine which are then transmitted and, therefore, affect the driver’s condition. The study of these vibrations is a subject frequently addressed by researchers, analyzing the influence of different parameters on the forces to which the pilot’s body or certain sensitive body parts are subjected. In this paper, we analyze the particular case of a racing car made to meet safety requirements in the event of an accident. For the analysis of the forced vibrations induced by the running track, the finite element method was used. This method proved to be a useful and stable modeling and analysis method, validated by practical applications. A standard-equipped racing car with a mannequin inside was studied. Once the natural frequencies of the structure were determined, the response of some points of the mannequin’s body to the movement caused by the running track or the engine was analyzed. Modeling and discretization were performed using well-known classical procedures. The obtained results revealed the parameters that can negatively influence the body of the mannequin which were communicated to the design team. The conclusion of this study is a racing car that was successfully used in Formula Student competitions.

The advancement of automotive technology is rapid in this era, as evidenced by the existence of autopilot vehicles that have been developed by a scientist. This progress is balanced with the knowledge that continues to develop in the world of education. Many prestigious automotive competitions are held to be a venue for student creativity and research in developing automotive technology, one of which is the Formula Student SAE. This is the background of a study to develop an engineered electric vehicle chassis, especially in Formula Student. This study aims to produce a chassis design that has torsional rigidity based on the selection of materials that have stiffness, strength, lightweight, and optimization of material cost. The structure of the vehicle was designed following Formula Student SAE regulations. To select material, initial screening was used by the Ashby method which produce 4 material types. Optimum of selecting the material used the Simple Additive Weighting (SAW) method. Meanwhile, chassis with material selected was analyzed by using Solidworks Simulation Education software. The results of this study produced Aluminum Alloys 7075-T6 material and torsional rigidity value of 552.65 x 103 Nmm/degree of chassis, which could achieve the minimum torsional rigidity value set at 500 x 103 Nmm/degree.
