Abstract

Peluru frangible memiliki kemampuan untuk terdisintegrasi menjadi fragmen-fragmen kecil ketika ditembakkan target keras atau disebut frangibilitas. Frangibilitas dapat mencegah dampak ricochet dan backsplash. Pada penelitian ini, pengujian frangibilitas dilakukan secara simulasi menggunakan metode explicit dynamics dengan solver ANSYS Autodyn yang terintegrasi oleh software ANSYS Workbench 18.1. Tujuan penelitan yaitu menganalisa frangibilitas peluru frangible melalui dua aspek yaitu material properties dan desain peluru. Dari hasil simulasi, FF peluru AMMO 1 dan AMMO 4 masing-masing adalah 12,93 dan 11,59. Error berdasarkan perbandingan FF hasil eksperimen dengan simulasi untuk peluru desain AMMO 1 dan desain AMMO 4 adalah sebesar 36,10% dan 0,08%. Dilakukan re-simulation pada peluru AMMO 1 agar didapatkan error yang lebih kecil dengan desain AMMO 1 yang telah dioptimasi, sehingga nilai FF menjadi 8,82 dengan error 7,14%. Secara visual pola hamburan peluru desain AMMO 4 menunjukkan jumlah partikel hamburan lebih banyak dibandingkan dengan desain AMMO 1, dengan jarak terjauh hamburan peluru AMMO 1 dan AMMO 4 1,01 meter dan 2,658 meter.

Frangible bullets has an ability to disintegrate into fragments by hitting a hard target objects. The ability to disintegrate is called frangibility. In this study, frangibility testing was tested theoretically by simulation using explicit dynamics method with ANSYS Autodyn solver integrated by ANSYS Workbench 18.1 software. The purpose of research is to analyze the frangible bullet frangibility through two aspects, material properties and design of the bullet. From the simulation results, the FF values of AMMO 1 and AMMO 4 bullets are 12.93 and 11.59 respectively. Errors based on FF comparison of experimental results with simulations for AMMO 1 design bullets and AMMO 4 designs are 36.10 % and 0.08 %. Re-simulation of AMMO 1 bullets is done to reach a smaller error using the optimized AMMO 1 design, so that the FF value becomes 8.82 with a 7.14% error. Based on simulation results, the AMMO 4 design bullet scattering pattern shows the number of scattering particles more than the AMMO 1 design, with the furthest distance scattering AMMO 1 and AMMO 4 bullets being 1.01 meters and 2.658 meters.
