Quasi-static crush, Aluminum silinder, Energi absorberAbstract
Energy absorber merupakan peralatan pengaman kendaraan yang diperlukan untuk melindungi penumpang kendaraan saat terjadi kecelakaan. Sejak awal tahun 1960 an, setelah Alexander memperkenalkan teorinya tentang penyerapan energi. Penemuan baru peralatan ini terus berkembang secara berkelanjutan. Bersamaan dengan berjalannya waktu, teori proses penyerapan energi pada peralatan ini juga terus dikembangkan oleh ilmuwan lainnya Tujuannya untuk memperoleh peralatan penyerap energi yang lebih baik. Sementara penelitian dibidang ini membutuhkan biaya yang tidak murah. Perkembangan teknologi komputer saat ini, analisa dengan metode elemen hingga dapat digunakan sebagai method alternatif. Persoalan yang ada terletak pada tingkat akurasi hasil simulasi bila dibandingkan dengan hasil percobaan. Hasil penelitian ini menunjukkan tingkat akurasi penggunaan teknologi simulasi baik. Hasil pengujian dan simulasi hampir sama, nilai penyerapan energi yang dihasikan maupun bentuk deformasi yang terjadi pada tabung silinder aluminium 6063-T5 dengan beban quasi-statics compresion crush menunjukkan hasil yang hampir sama.Downloads
