Abstract

Ban-ban konvensional memiliki risiko kebocoran dan pecah ban yang dapat memengaruhi keselamatan berkendara, sehingga diperlukan alternatif berupa Non-pneumatic Tire (NPT). Penelitian ini bertujuan menganalisis pengaruh variasi geometri spoke honeycomb dan kecepatan terhadap respons mekanik ban non-pneumatic sepeda motor serta membandingkan respons mekanik Model A dan Model B. Penelitian dilakukan menggunakan metode Finite Element Method (FEM) dengan analisis Transient Structural pada ANSYS Workbench 2026 R1. Model A dan Model B dirancang menggunakan Autodesk Inventor 2025 dan disimulasikan pada kecepatan 20, 40, 60, dan 80 km/jam dengan beban sebesar 1425 N. Beban tersebut diperoleh dari asumsi distribusi 60% beban total kendaraan dan dua penumpang pada roda belakang. Parameter yang dianalisis meliputi Equivalent (von Mises) Stress, Maximum Shear Stress, Strain Energy, dan Safety Factor. Hasil penelitian menunjukkan bahwa variasi geometri dan kecepatan memengaruhi respons mekanik struktur spoke honeycomb. Peningkatan kecepatan menyebabkan perubahan nilai Equivalent Stress, Maximum Shear Stress, dan Strain Energy, serta kecenderungan penurunan Safety Factor. Perbandingan kedua model menunjukkan adanya perbedaan respons mekanik pada setiap variasi kecepatan. Model B secara umum menunjukkan respons tegangan yang lebih terkendali dan kemampuan menyimpan energi elastis yang lebih tinggi dibandingkan Model A. Analisis ini digunakan untuk menentukan pengaruh kecepatan dan geometri terhadap karakteristik mekanik struktur selama pembebanan dinamis secara dinamis. Simulasi juga mempertimbangkan interaksi kontak antara tread dan permukaan jalan dengan koefisien gesek. Hasil setiap variasi dibandingkan untuk mengidentifikasi perubahan distribusi tegangan, kemampuan struktur menyimpan energi elastis, dan tingkat keamanan berdasarkan nilai Safety Factor sebagai dasar pemilihan geometri paling sesuai untuk aplikasi ban non-pneumatic sepeda motor./***** Conventional tires are susceptible to punctures and tire blowouts, which can compromise driving safety, necessitating alternatives such as Non-pneumatic Tires (NPT). This study aims to analyze the effects of spoke honeycomb geometry and speed variations on the mechanical response of motorcycle non-pneumatic tires and to compare the mechanical responses of Model A and Model B. The research was conducted using the Finite Element Method (FEM) with Transient Structural analysis in ANSYS Workbench 2026 R1. Models A and B were designed using Autodesk Inventor 2025 and simulated at speeds of 20, 40, 60, and 80 km/h with a load of 1425 N. The load was determined based on an assumed distribution of 60% of the total vehicle and two-passenger load acting on the rear wheel. The analyzed parameters included Equivalent (von Mises) Stress, Maximum Shear Stress, Strain Energy, and Safety Factor. The results indicate that variations in geometry and speed affect the mechanical response of the spoke honeycomb structure. Increasing speed causes changes in Equivalent Stress, Maximum Shear Stress, and Strain Energy, along with a tendency for the Safety Factor to decrease. Comparison of the two models shows differences in mechanical responses at each speed variation. Model B generally exhibits a more controlled stress response and a higher capacity to store elastic energy than Model A. This analysis is used to determine the effects of speed and geometry on the mechanical characteristics of the structure under dynamic loading. The simulation also considers contact interaction between the tread and road surface with a friction coefficient. The results for each variation were compared to identify changes in stress distribution, the structure's ability to store elastic energy, and the level of safety based on the Safety Factor as a basis for selecting the most suitable geometry for motorcycle non-pneumatic tire applications.
