Abstract
Non-Pneumatic Tires (NPT) have been used in several sectors since the wide application and following with advantages of the simplicity in maintenance. In this paper, the static and explicit dynamic behavior of NPTs is investigated with several different honeycomb spokes. The component of NPT with a hexagonal honeycomb type consists of a hub wheel, outer ring, spokes, and tread. The six models of NPT are denoted with the variation of spokes thickness (20 and 30 mm) and thickness of the wheel tread (3, 5 and 7 mm). Based on the computer simulation results, the B3 type NPT has an excellent ability to accept loads with deformation, which is 14,358 mm and the stress is 270 MPa.

Summary
Penelitian ini diselesaikan dengan menggunakan simulasi komputer yaitu menggunakan software ANSYS Workbench 16.2 untuk proses awal dan penyelesaiannya. Gambar 1 menunjukkan ban tanpa udara dengan tipe sarang lebah heksagonal yang terdiri dari roda hub, lingkar luar, jari-jari, dan tapak. Lingkar luar terbuat dari baja berkekuatan tinggi ANSI 4340 dengan densitas = 7800 kg⁄m3, E = 210 GPa, dan Poisson rasio = 0,29. Jari-jari sarang lebah heksagonal terbuat dari bahan Poliuretan dengan densitas = 1200 kg⁄m3, E = 32 MPa, dan Poisson rasio = 0,49. Tabel 2 menunjukkan enam model NPT yang diatur dengan variasi ketebalan jari-jari dan ketebalan tapak. Tabel 3 dan Gambar 4 menunjukkan hasil simulasi pada 6 jenis model ban tanpa udara dengan pembebanan statis dan dinamis. Grafik Hasil Simulasi Statis dan Dinamis Pada simulasi statis dan dinamik terlihat bahwa NPT tipe A2 menghasilkan deformasi dan equivalent stress yang paling tinggi, dengan tebal dinding jari-jari 5 mm dan tebal tapak 20 mm. Gambar 5 dan 6 menunjukkan Plot deformasi dan equivalent stress pada uji model statis
