Abstract

Setiap industri mobil terus berusaha meningkatkan invoasi keamanan pada kendaraan mobil. Salah satu inovasi yang dikembangkan adalah Crash box yang mana pengembangan perlu dilakukan demi keamanan kendaraan ketikan mobil kecelakaan atau tabrakan mobil (Crashworthiness). Dan perlu dilakukan pengembangan desain terhadap kelayakan tabrak mobil pada saat kecelakaan.
Pada Tesis ini akan dikembangkan beberapa desain dan penggunaan material yang tepat pada Crash box. Dan dilakukan Studi Numerikal dengan simulasi Finite Element Menggunakan Sofware Ansys Explicit Dynamics. Di mana hal ini dilakukan untuk mendapatkan hasil parameter Crashworthiness pada desain Crash box yang mencakup Penyerapan Energi (High Energy absorption) pada saat kecelakaan Full Frontal Impact dan diharapkan mampu mengurangi kerusakan pada mobil dan Cedera Fisik Pengemudi.
Pada Penelitian Ini didapatkan Hasil dengan Model Crash box Square dengan Penambahan Honeycomb, Front End Triggerm dan Trigger Slot (Model Square 3) Mempunyai Nilai Crashworthiness Struktur yang terbaik dibandingkan model lainnya, Model Square 3 Mempunyai Nilai Energi Absorption (EA) Sebesar 158,25 Kj, Specific Energi Absorption (SEA) 383,90 Kj, Initial Peak Force (IPF) 2713,3 Kn, Mean Crushung Force (MCF) 2886,67 kJ/mm, dan Crush Force Efficency (CFE) 106,39%. Dapat menaikkan Penyerapan Energi struktur sebanyak 362,5% di banding Base Model.

Every car industry continuously strives to improve safety innovations in vehicles. One of the innovations being developed is the Crash box, which needs to be further developed for vehicle safety during crashes (Crashworthiness). Design development is also required to ensure vehicle Crashworthiness during accidents.
This thesis will develop several designs and use appropriate materials for the Crash box. A numerical study will be conducted using Finite Element simulations with Ansys Explicit Dynamics software. This is done to obtain Crashworthiness parameters in the Crash box design, which includes high energy absorption during full frontal impact crashes and is expected to reduce vehicle damage and physical injuries to the driver.
In this study, results showed that the Square Crash box model with the addition of Honeycomb, Front End Trigger, and Trigger Slot (Square Model 3) has the best structural Crashworthiness values compared to other models. Square Model 3 has an Energi Absorption (EA) value of 158.25 kJ, Specific Energi Absorption (SEA) of 383.90 kJ, Intial Peak Force (IPF) of 2713.3 kN, Mean Crushing Force (MCF) of 2886.67 kJ/mm, and Crush Force Efficency (CFE) of 106.39%. It can increase the structural energy absorption by 362.5% compared to the base model.
