Abstract

Ban non pneumatic merupakan salah satu inovasi pada sistem roda yang dikembangkan untuk mengatasi kelemahan ban konvensional, terutama menanggulangi risiko kebocoran dan kehilangan tekanan udara selama pengoperasian. Kinerja ban non pneumatic sangat dipengaruhi oleh geometri struktur spoke yang berfungsi menopang beban dan mendistribusikan gaya selama proses rolling. Penelitian ini bertujuan menganalisis pengaruh variasi sudut spoke terhadap respons mekanis pada struktur spoke trapezoid ban non pneumatic sepeda motor. Pemodelan geometri dilakukan menggunakan Autodesk Inventor 2025, sedangkan analisis numerik dilakukan menggunakan ANSYS Workbench 2026 R1 melalui simulasi Transient Structural. Variasi sudut spoke yang digunakan adalah 10° dan 15° dengan variasi kecepatan 20, 40, 60, dan 80 km/jam. Material spoke menggunakan polyurethane, sedangkan parameter yang dianalisis meliputi strain energy, maximum shear stress, equivalent stress, dan safety factor. Hasil simulasi menunjukkan bahwa peningkatan kecepatan putar memengaruhi respons mekanis struktur spoke. Dibandingkan desain 10°, struktur spoke dengan sudut 15° menghasilkan nilai strain energy yang lebih tinggi,menunjukkan kemampuan struktur dalam menyerap dan menyimpan energi elastis akibat pembebanan secara lebih efektif. Selain itu, desain 15° menghasilkan nilai maximum shear stress dan equivalent stress yang lebih rendah sehingga distribusi beban menjadi lebih merata dan konsentrasi tegangan dapat diminimalkan. Kondisi tersebut berdampak pada nilai safety factor yang lebih tinggi dibandingkan desain 10°, sehingga menunjukkan tingkat keamanan struktur yang lebih baik selama menerima pembebanan dinamis. Berdasarkan hasil penelitian, variasi sudut spoke berpengaruh terhadap respons mekanis ban non pneumatic, dan struktur spoke trapezoid dengan sudut 15° direkomendasikan sebagai desain yang lebih optimal untuk aplikasi pada ban non pneumatic sepeda motor ***** Non-pneumatic tires are an innovative wheel system developed to overcome the limitations of conventional pneumatic tires, particularly the risks of punctures and pressure loss during operation. The performance of non-pneumatic tires is strongly influenced by the geometry of the spoke structure, which functions to support the applied load and distribute forces during rolling. This study aims to analyze the effect of spoke angle variation on the mechanical response of a trapezoidal spoke structure for a motorcycle non pneumatic tire. The tire geometry was modeled using Autodesk Inventor 2025, while the numerical analysis was performed using ANSYS Workbench 2026 R1 through a Transient Structural simulation. Two spoke angle variations, 10° and 15°, were evaluated under operating speeds of 20, 40, 60, and 80 km/h. The spoke structure was made of polyurethane, and the mechanical response was evaluated based on strain energy, maximum shear stress, equivalent stress, and safety factor. The simulation results indicate that increasing rotational speed affects the mechanical response of the spoke structure. Compared with the 10° design, the 15° spoke configuration exhibited higher strain energy, indicating a greater capability to absorb and store elastic energy under loading. Furthermore, the 15° design produced lower maximum shear stress and equivalent stress, resulting in a more uniform load distribution and reduced stress concentration. Consequently, the 15° spoke structure achieved a higher safety factor, indicating better structural reliability under dynamic loading conditions. Based on these findings, the spoke angle significantly influences the mechanical response of non-pneumatic tires, and the trapezoidal spoke structure with a 15° spoke angle is recommended as the optimal design for motorcycle non-pneumatic tire applications.
