Abstract

Perkembangan kendaraan berbasis listrik di Indonesia terus mengalami peningkatan, termasuk dalam dunia balap motor drag. Salah satu tantangan utama dalam pengembangan sepeda motor drag listrik adalah merancang rangka yang mampu menahan beban berat komponen listrik seperti baterai dan motor listrik, tanpa mengorbankan performa akselerasi dan
stabilitas kendaraan. Penelitian ini bertujuan untuk merancang rangka sepeda motor drag listrik yang optimal dari sisi kekakuan dan kekuatan struktur menggunakan metode elemen hingga. Penelitian diawali dengan perumusan masalah mengenai kebutuhan rangka yang kuat dan ringan, dengan pembatasan pada analisis desain rangka tanpa mempertimbang-kan getaran. Pemodelan dilakukan dalam bentuk desain 3D pada soft ware Solidworks, dua desain rangka menggunakan material AISI 1020. Analisis numerik melalui perangkat lunak ANSYS, simulasi digunakan untuk mengevaluasi kekakuan torsional, longitudinal, dan lateral serta respons rangka terhadap pembebanan statis dan dinamis dalam kondisi akselerasi dan deselerasi. Berdasarkan analisa yang dilakukan, desain 2 memiliki performa struktural yang lebih baik dibanding desain 1. Nilai torsional stiffness desain 2 mencapai 3,2 kNm/deg, longitudinal stiffness 5,9 kN/mm, dan lateral stiffness 2 kN/mm. Sedangkan desain 1 hanya mencapai 2,4
kNm/deg, 1,6 kN/mm, dan 0,17 kN/mm. Pada simulasi kekuatan, desain 2 mampu menahan beban statis dengan deformasi maksimum 0,16 mm dan tegangan maksimum 36,949 MPa, serta
deformasi kondisi akselerasi dan deselerasi masing-masing 0,15 mm dan 0,17 mm. Seluruh nilai tegangan berada di bawah tegangan izin AISI 1020 sebesar 350 MPa, sehingga desain
dinyatakan aman dan layak digunakan.

The development of electric vehicles in Indonesia continues to increase, including in the world of drag racing. One of the main challenges in developing electric drag bikes is
designing a frame that can withstand the heavy weight of electrical components such as batteries and electric motors without sacrificing the vehicle's acceleration and stability. This study aims to design an optimal electric drag bike frame in terms of stiffness and structural strength using the finite element method. The study began with the formulation of the problem regarding the need for a strong yet lightweight frame, with the constraint of analyzing the frame design without considering vibrations. Modeling was conducted in 3D design using SolidWorks software, with two frame designs utilizing AISI 1020 material. Numerical analysis was conducted using ANSYS
software, with simulations used to evaluate torsional, longitudinal, and lateral stiffness, as well as the frame's response to static and dynamic loading under acceleration and deceleration conditions. Based on the analysis onducted, Design 2 demonstrates better structural performance
compared to Design 1. The torsional stiffness of Design 2 reaches 3.2 kNm/deg, longitudinal stiffness 5.9 kN/mm, and lateral stiffness 2 kN/mm, while Design 1 only achieves 2.4 kNm/deg, 1.6 kN/mm, and 0.17 kN/mm, respectively. In the strength simulation, Design 2 is capable of withstanding static loads with a maximum deformation of 0.16 mm and a maximum stress of 36.949 MPa, as well as deformation under acceleration and deceleration conditions of 0.15 mm
and 0.17 mm, respectively. All stress values are below the allowable stress limit of AISI 1020, which is 350 MPa, indicating that the design is safe and feasible for use.
