Abstract

Mobil listrik semakin populer, mendorong Nogogeni untuk mengembangkan kendaraan listrik sebagai alternatif bahan bakar fosil. Tim Nogogeni ITS berpartisipasi dalam perlombaan Teknofest untuk menciptakan mobil ramah lingkungan dengan fokus pada keamanan dan kenyamanan, khususnya dalam desain sistem kaki-kaki dan komponen upright mobil double seat. Penelitian ini bertujuan merancang komponen upright yang kuat, menggunakan material Al 6061 dan Al 7075, serta mengevaluasi tegangan, deformasi, safety factor, dan fatigue life melalui simulasi. Metode perancangan komponen upright menggunakan SolidWorks 2020 untuk desain parametrik, menghasilkan file komponen dan gambar terkait. Simulasi dengan finite element analysis hingga menganalisis tegangan pada rangka, fokus pada variabel von mises stress, deformasi, dan safety factor untuk memilih desain terbaik. Setelah dilakukan penelitian ini didapatkan upright dengan material Al 6061 memiliki massa 369,85 gram sedangkan dengan material Al 7075 memiliki massa 384,92 gram. Sehingga material Al 6061 lebih ringan dibanding Al 7075. Nilai deformasi Al 6061 lebih besar 10,36x dari material Al 7075. Nilai tegangan upright yang terjadi sama pada material Al 6061 dan Al 7075 sebesar 42,54 MPa saat akselerasi, 42,57 MPa saat deselerasi, dan 106,48 MPa saat berbelok. Nilai safety factor upright menggunakan material Al 6061 sebesar 6,49 saat akselerasi, 6,48 saat deselerasi, 2,6 saat berbelok sedangkan material Al 7075 sebesar 11,82 saat akselerasi, 11,82 saat deselerasi, 4,72 saat berbelok. Nilai life cycle dari Material Al 7075 lebih besar dari Al 6061. Kondisi yang paling ekstream diterima upright yakni kondisi berbelok. Dan material Al 7075 mampu menahan beban hingga 200 kg dan memenuhi desain kriteria.===============================================================================================================Electric cars are growing in popularity, prompting Nogogeni to develop electric vehicles as an alternative to fossil fuels. The Nogogeni ITS team participated in the Teknofest competition to create an environmentally friendly car with a focus on safety and comfort, especially in the design of the leg system and upright components of the double seat car. This research aims to design strong upright components, using Al 6061 and Al 7075 materials, and evaluate stress, deformation, safety factor, and fatigue life through simulation. The upright component design method uses SolidWorks 2020 for parametric design, generating component files and related drawings. Simulation with the finite element method analyses the stress in the frame, focusing on von mises stress, deformation, and safety factor variables to select the best design. After this research, it was found that the upright with Al 6061 material has a mass of 369.85 grams while the Al 7075 material has a mass of 384.92 grams. So that the Al 6061 material is lighter than Al 7075. The deformation value of Al 6061 is 10.36x greater than Al 7075 material. The upright stress value that occurs is the same in Al 6061 and Al 7075 materials of 42.54 MPa when accelerating, 42.57 MPa when decelerating, and 106.48 MPa when turning. The upright safety factor value using Al 6061 material is 6.49 when accelerating, 6.48 when decelerating, 2.6 when turning while Al 7075 material is 11.82 when accelerating, 11.82 when decelerating, 4.72 when turning. The life cycle value of Al 7075 material is greater than Al 6061. The most extreme condition received by the upright is the turning condition. And Al 7075 material is able to withstand loads of up to 200 kg and meets the design criteria.
