“…With the designed chassis FEA method, the condition of the chassis under stress was examined with ANSYS program. Thus, the chassis design was realized with an accurate ultra-fast and cost-effective method [23]. A structurally balanced chassis was designed for an electric motorcycle in a 2018 study by Joel et al simulated the real-time forces on the chassis and suspension geometries.…”

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.

Metode Elemen Hingga (MEH) merupakan salah satu metode yang dapat digunakan untuk mendesain dan menganalisis kekuatan rangka chassis mobil. Penelitian ini bertujuan untuk mendesain rangka serta melakukan assessment pada desain tersebut. Dalam penelitian ini, MEH diterapkan melalui proses komputasi dengan bantuan Autodesk Inventor untuk mendesain rangka dan Autodesk Robot Structural Analysis untuk melakukan assessment. Material pipa logam yang digunakan berspesifikasi Steel AISI 1020 107 HR dan jenis rangka yang dipilih adalah model tubular space frame. Asumsi dimensi rangka mengambil contoh dari desain BMW i3 yang merupakan mobil listrik 4 penumpang. Beban yang diberikan berupa beban statis yang terdiri atas beban penumpang, beban kursi penumpang, beban baterai, dan beban motor listrik. Pada hasil desain, rangka terdiri atas 134 elemen dan 107 node dengan ukuran 2 in. x 0.154 in. pada dasar rangka dan 1.5 in. x 0.145 in. pada keseluruhan sisanya. Perpindahan maksimal terletak pada node 175 dengan nilai 1,3164 mm. Besar dan posisi gaya maksimal untuk tiap sumbu rangka adalah Fx: 1985,126 N (node 225), Fy: 959,480 N (node 14), dan Fz: 935,914 N (node 34). Tegangan maksimal terletak pada node 129 dengan nilai 35,443 MPa. Regangan maksimal terletak pada bar 70 dengan nilai 0,00450474. Dapat disimpulkan bahwa desain rangka mampu menahan beban yang diberikan dan tidak mengalami kerusakan.

“…On the other hand, there has been a need for lower conceptual design costs within a shorter time frame, and there has also been a need for new modeling techniques, which has led automotive manufacturers to find better ways to develop vehicles. Simulation through finite element analysis (FEA) is a cost and time efficient way to develop vehicle chassis while utilizing the saved time for innovative product development [8]. The modeling methodology of chassis is another important advantage associated with using FEA as it helps in studying the Steven Odi-Owei 1 , Emeka Obiora Anisiji 1 , and Frank Efe Erukainure 1*…”

This paper presents the design, modelling, and fabrication procedures for the chassis of a prototype car with the aim of achieving the objectives: rigid and high strength chassis, reduced vehicle weight, driver safety, and an energy efficient vehicle. The novelty of this work is that it demonstrates how aluminium alloy could be used to construct non-integrated chassis for super mileage vehicles through a load-stress calculation model. Furthermore, a method of Finite Element Analysis (FEA) was presented which achieves the same result as the analytical calculation. The work also presents a method of fabricating aluminium square tube for the chassis by joining two angle bars. The results show that the FEA approach agrees with the analytical design model thereby reducing the time consumed in conceptual design process. The fabricated chassis was found to show no cracks and it was able to resist bending and shear from the loads acting on the vehicle in line with the design data. The energy efficiency recorded from the first test-run of the vehicle was 250 km/L of gasoline. The methods presented could be characterized as accurate and reliable for manufacturers of super mileage racing cars for Shell Eco-marathon events.
