Rangka sepeda motor listrik, Analisis modal, Frekuensi alami, Structural steel, Titanium alloyAbstrak
Perkembangan sepeda motor listrik menuntut struktur rangka yang memiliki karakteristik dinamis yang baik untuk menjamin kestabilan, kenyamanan, dan keamanan selama beroperasi. Penelitian ini bertujuan untuk menganalisis pengaruh material Structural Steel dan Titanium Alloy terhadap frekuensi alami dan bentuk mode getar rangka sepeda motor listrik menggunakan ANSYS Workbench 2024 R1. Metode penelitian dilakukan melalui pembuatan model rangka 3D, penentuan sifat material, penerapan kondisi batas free-free, proses meshing, serta simulasi modal analysis untuk memperoleh dua belas mode getar pertama. Hasil penelitian menunjukkan bahwa mode 1–6 pada kedua material memiliki frekuensi yang mendekati nol yang menandakan rigid body motion, sedangkan mode elastik yang relevan mulai muncul pada mode 7–12. Rangka berbahan Structural Steel menghasilkan frekuensi alami yang lebih tinggi dibandingkan Titanium Alloy, yaitu 60.101 Hz dan 54.166 Hz pada mode 7, serta 107.51 Hz dan 96.803 Hz pada mode 12. Hasil ini menunjukkan bahwa Structural Steel memiliki kekakuan dinamis yang lebih baik dibandingkan Titanium Alloy pada geometri rangka yang sama. Dapat disimpulkan bahwa pemilihan material berpengaruh signifikan terhadap respons dinamis rangka sepeda motor listrik. Penelitian selanjutnya disarankan untuk mempertimbangkan kondisi pembebanan aktual, eksitasi jalan, dan validasi eksperimental agar diperoleh hasil yang lebih komprehensif.
