Abstract

Penelitian ini menganalisis pengaruh variasi sudut rotasi spoke, volume fraction sel RPAS (Rotated Primitive-based Auxetic Structure), dan tipe alur tapak terhadap kinerja mekanik ban non-pneumatik ukuran 130/70 R13 untuk sepeda motor. Model geometri didesain menggunakan Autodesk Inventor 2025, sedangkan analisis numerik dilakukan pada ANSYS Static Structural. Simulasi statis dilakukan pada beban sebesar 1.600 N dengan penyederhanaan jumlah simulasi menggunakan Taguchi L16 untuk kombinasi ketiga faktor tersebut. Hasil yang dianalisis meliputi deformasi maksimum dan gaya rolling resistance yang dikonversi menjadi koefisien rolling resistance. Hasil menunjukkan bahwa volume fraction merupakan faktor dominan yang memberikan kontribusi terbesar terhadap variasi deformasi (50,64%) dan koefisien rolling resistance (56%), sedangkan sudut rotasi dan tipe alur tapak memberikan pengaruh lebih kecil untuk optimasi desain. Secara umum, sudut rotasi yang semakin tinggi akan semakin menurunkan deformasi, tetapi meningkatkan koefisien rolling resistance. Volume fraction optimal berada di tingkat -1,30 berdasarkan deformasinya dan -1,20 berdasarkan koefisien rolling resistance-nya. Alur tapak terbaik adalah jenis lug kompleks berdasarkan deformasi dan koefisien rolling resistance-nya. Meskipun uji ANOVA pada tingkat signifikansi 0,05 tidak menunjukkan perbedaan yang signifikan antar level, analisis kontribusi faktor memperjelas prioritas untuk optimasi kedepannya. Temuan penelitian merekomendasikan fokus awal pada penentuan volume fraction optimal untuk RPAS sebelum melakukan penyesuaian sudut rotasi dan pengembangan pola alur tapak. ***** This study analyzes the effect of variations in the spoke rotation angle, the volume fraction of the RPAS (Rotated Primitive-based Auxetic Structure) cell, and the tread groove type on the mechanical performance of a 130/70 R13 non-pneumatic tire for motorcycles. The geometry model was designed using Autodesk Inventor 2025, while the numerical analysis was performed on ANSYS Static Structural. Static simulations were performed at a load of 1,600 N with a simplified number of simulations using Taguchi L16 for the combination of the three factors. The analyzed results include maximum deformation and rolling resistance force converted into rolling resistance coefficient. The results show that the volume fraction is the dominant factor that gives the largest contribution to the variation of deformation (50.64%) and rolling resistance coefficient (56%), while the rotation angle and tread groove type have a smaller influence on design optimization. In general, a higher rotation angle will further reduce deformation, but increase the rolling resistance coefficient. The optimal volume fraction is at -1.30 based on its deformation and -1.20 based on its rolling resistance coefficient. The best tread pattern was a complex lug type based on its deformation and rolling resistance coefficient. Although ANOVA at the 0.05 significance level did not show significant differences between levels, factor contribution analysis clarified priorities for future optimization. The study findings recommend an initial focus on determining the optimal volume fraction for RPAS before adjusting the rotation angle and developing the tread pattern.
