Ulfa, Dewi Mariya (2019) Optimasi Parameter Desain Crash Box With Honeycomb Filler dengan Response Surface Methodology untuk Peningkatan Specific Energy Absorption. Sarjana thesis, Universitas Brawijaya.
Abstract
Crash box adalah suatu komponen keselamatan pasif yang berfungsi sebagai penyerap energi tabrak yang terpasang di antara bumper dan rangka utama pada mobil. Saat ini penambahan filler pada crash box banyak dikembangkan, salah satunya adalah penambahan honeycomb sebagai filler crash box yang bertujuan untuk memaksimalkan penyerapan energi. Tujuan dari penelitian ini untuk mendapatkan kondisi optimum parameter desain Crash Box with Honeycomb Filler. Penelitian ini menggunakan metode simulasi komputer dengan software berbasis Metode Elemen Hingga. Parameter desain yang digunakan adalah tebal crash box (T), panjang honeycomb dari atas (HU) dan panjang honeycomb dari bawah (HL) terhadap Spesific Energy Absorption (SEA) menggunakan Response Surface Methodology (RSM). Crash Box with Honeycomb Filler ditabrak oleh impactor menggunakan konsep Instrumented Drop Mass Setup, di mana massa impactor adalah 600 kg dan kecepatannya 15 m/s. Berdasarkan hasil dari simulasi, desain optimum Crash Box with Honeycomb Filler yang dipilih adalah desain dengan T=1.6999 mm, HU= 40.0184 mm, HL= 40.0466 mm. Model crash box tersebut memiliki nilai Spciific Energy Absorption sebesar 45058.4220J/ kg dan force reaction sebesar 84115.8739 N. Semakin besar nilai T, akan meningkatkan nilai SEA, sedangkan semakin besar nilai HU dan HL maka akan menurunkan SEA.
English Abstract
Crash box is a passive safety component that functions as an energy absorber which installed between the bumper and main frame of the car. Currently the addition of fillers in the crash box is widely developed, one of the addition is honeycomb as a crash box fill that aims to maximize energy absorption. The purpose of this study is to obtain optimum conditions for the design parameters of Crash Box with Honeycomb Filler. This study uses computer simulation methods with software based on the Finite Element Method. The design parameters are the crash box thickness (T), the length of the honeycomb from the top (HU) and the length of the honeycomb from the bottom (HL) to Specific Energy Absorption (SEA) using Response Surface Methodology (RSM). Crash Box with Honeycomb Filler is impacted by an impactor using the Instrumented Drop Mass Setup concept, the mass of impactor is 600 kg and the velocity is 15 m / s. Based on the results of the simulation, the optimum design of Crash Box with Honeycomb Filler is the design with T = 1.6999 mm, HU = 40.0184 mm, HL = 40.0466 mm. The crash box model has a Specific Energy Absorption value of 45058.4220 J / kg and a force reaction of 84115.8739 N. Increase of the value of crash box thickness (T), Specific Energy Absorption (SEA) increased whilst the increase of HU and HL will decrease SEA.
