Abstract

Tim Nogogeni ITS menjalankan riset dan mengikuti kompetisi kendaraan hemat energi. Pada Kontes Mobil Hemat Energi 2024, mobil urban listrik Nogogeni IX Evo mengalami kendala akibat ketiadaan sistem transmisi pemutus dan penyambung daya. Penggunaan freewheel clutch yang dihubungkan dengan chain & sprocket menyebabkan gesekan tinggi, waktu gliding saat deselerasi lebih cepat, dan meningkatkan konsumsi energi. Untuk mengatasi hal tersebut, sistem transmisi dirancang ulang menggunakan jaw clutch untuk mengurangi gesekan dan memperpanjang waktu gliding. Penelitian ini bertujuan untuk mendapat rancangan jaw clutch yang kuat dan aman untuk digunakan mobil urban listrik Nogogeni X Evo. Penelitian dimulai dengan membandingkan variasi desain jumlah gigi cakar 10 dan jumlah gigi cakar 12 serta menggunakan variasi material ST 37, Al 7075, dan Al 6061 yang memenuhi kriteria desain. Kriteria desain dari penelitian ini adalah tegangan kerja lebih kecil dari tegangan ijin material, safety factor lebih dari 2, dan massa yang ringan. Metode penelitian dimulai dengan studi literatur dan observasi lapangan, dilanjutkan perhitungan diameter jaw clutch, pemodelan desain menggunakan perangkat lunak CAD, serta penentuan boundary condition dilanjutkan proses meshing. Proses dilanjutkan dengan uji konvergensi dan simulasi static structural menggunakan finite element analysis yang berfokus pada analisa static structural dengan mengevaluasi von mises stress, total deformation, dan safety factor. Berdasarkan hasil peneltian didapatkan rekomendasi desain dari 2 variasi desain dan 3 variasi material yang digunakan. Dari 6 variasi rancangan jaw clutch dipilih variasi desain jaw clutch gigi cakar 10 dengan material Al 7075 karena memiliki von mises stress sebesar 21,241 Mpa, total deformation 0,017378 mm, safety factor 15, dan massa sebesar 177,56 gram. Hasil tersebut memenuhi kriteria desain yang ditentukan karena memberikan keseimbangan antara kekuatan mekanik dan massa yang ringan.

The Nogogeni ITS team conducts research and participates in energy-efficient vehicle competitions. In 2024 at Kontes Mobil Hemat Energi, Nogogeni IX Evo electric urban car experienced problems due to the absence of a transmission system for breaking and connecting power. The use of freewheel clutch connected by chain & sprocket causes high friction, faster gliding time during deceleration, and increases energy consumption. To overcome this, the transmission system was redesigned using a jaw clutch to reduce friction and extend gliding time. This research aims to obtain a robust and safe jaw clutch design for use in the Nogogeni X Evo electric urban car. The research began by comparing design variations of the number of claw teeth 10 and the number of claw teeth 12 and using variations of ST 37, Al 7075, and Al 6061 materials that meet the design criteria. The design criteria of this research are working stress smaller than the material allowable stress, safety factor more than 2, and light mass. The research method begins with a literature study and field observations, followed by the calculation of the jaw clutch diameter, design modeling using CAD software, and determination of boundary conditions followed by the meshing process. The process continued with convergence test and static structural simulation using finite element analysis which focused on static structural analysis by evaluating von mises stress, total deformation, and safety factor. Based on the results of the research, design recommendations were obtained from 2 design variations and 3 variations in the materials used. Of the 6 jaw clutch design variations, the 10 claw tooth jaw clutch design variation with Al 7075 material was chosen because it has a von mises stress of 21,241 Mpa, a total deformation of 0,017378 mm, a safety factor of 15, and a mass of 177,56 grams. These results meet the specified design criteria because they provide a balance between mechanical strength and light mass.
