Abstract

Konversi kendaraan Internal Combustion Engine (ICE) menjadi kendaraan Listrik dapat mempercepat peningkatan jumlah populasi Electric Vehicle (EV) yang mengurangi emisi gas carbon. Makalah ini menjelaskan proses analisis statik yang merupakan salah satu bagian penting saat mengkonversi bus berbasis ICE menjadi bus listrik. Bus yang dikonversi perlu memperhatikan pembebanan statik, khususnya berat dan posisi Center of Gravity (CoG) pada struktur sasis karena mempengaruhi performa Bus. Penimbangan massa dilakukan pada sasis untuk mengetahui letak CoG setiap kondisi. Massa sasis dengan muatan komponen elektrik setelah ditimbang adalah 2774 kg sedangkan massa sasis model CAD 2760,78 kg. Persentase error massa sasis pada CAD terhadap massa sasis hasil pengukuran cukup baik, yaitu 0,48%. Total perhitungan massa komponen elektrik dan upperstructure adalah 1612 kg dan 2854,4 kg. Analisis distribusi beban sepanjang sasis menggunakan pendekatan Finite Element Analysis dengan menerapkan metode analisis linear statik. Pembebanan komponen elektrik menghasilkan maksimum displacement 3,49 mm, von Mises stress 78,47 MPa dan reaction force -577,4 N pada sasis. Sedangkan, pembebanan total dengan menambahkan upperstructure menghasilkan maksimum displacement 4,58 mm, von Mises stress 83,95 MPa, dan reaction force -1174 N dengan nilai safety factor 5,24. Perbandingan error nilai defleksi suspensi depan dan belakang antara simulasi dengan teoritik adalah 4,99% dan 4,93%. Hasil investigasi menunjukan nilai kekakuan pada suspensi pegas daun depan dan belakang masing-masing sekitar 285 N/mm dan 320 N/mm. Selain itu, struktur sasis dengan pembebanan total mengalami tegangan maksimum di sekitar suspensi belakang.

Abstract

This paper presents a comprehensive design methodology and mechanical evaluation of an electric motorcycle battery pack that fulfils both international safety standards and Indonesian regulations. As the country with the world’s largest motorcycle fleet, Indonesia faces significant challenges in transitioning to electric mobility—particularly in preventing battery malfunctions and mitigating accident risks. The design process begins by defining minimum technical requirements, ensuring regulatory compliance, and addressing geometric constraints, then moves on to develop component architectures in accordance with industry best practices. Detailed models of the pack and its subassemblies are subjected to finite element analysis to verify structural integrity under demanding operational conditions. Key performance targets include an IP68 ingress protection rating, sufficient rigidity to withstand vibrational loads, and impact resistance for accident scenarios. Simulation results confirm that the final design maintains mechanical robustness across a variety of load cases. Building on these findings, the paper offers specific recommendations to further enhance pack performance and safety. The described methodology is fully reproducible and provides practical insights for efficient product development, even when resources are limited.
