Abstract

Beban Impact pada baterai pack fin komodo akan mengakibatkan kerusakan mounting baterai pack pada struktur kendaraan. Desain eksisting mempunyai risiko mudah terlepas apabila diberi beban Impact dengan kecepatan yang rendah. Keamanan dari sambungan ini dapat ditingkatkan dengan ditambahkan material yang mendisipasikan energi Impact yaitu adhesive. Penulis mengusulkan adhesive hybrid joint untuk mounting baterai pack fin komodo untuk menyerap energi tumbukan sehingga mengurangi kerusakan pada sambungan.
Penelitian ini menggunakan metode elemen hingga untuk mengamati serapan energi dan tegangan akibat beban impact pada sambungan baterai pack. Ketebalan, jenis adhesive dan kecepatan impact akan menjadi variabel dari penelitian ini. Metode penelitian ini menggunakan indentor yang mengacu pada standar J2464 mengenai abuse testing pada Battery Pack. Indentor diberikan initial velocity sebagai beban impact pada Battery Pack. Kemudian akan diamati nilai serapan energi impact maksimum yang mampu diterima oleh mounting.
Melalui penelitian ini diperoleh bahwa adanya hubungan antara ketebalan adhesive terhadap serapan energi Impact yang diterima sambungan. Ketebalan 0,2 mm hingga 2 mm memiliki hubungan monoton naik sedangkan pada ketebalan 2 mm hingga 4 mm memiliki hubungan monoton turun. Serapan energi tertinggi terjadi pada Epoxy 3501-6 ketebalan 2 mm dimana adhesive ini memiliki nilai modulus yang paling rendah dibandingkan adhesive lainnya yang digunakan. Terdapat kenaikan kecepatan maksimum dari impactor sebesar 16 %. Implikasi penelitian ini yaitu terdapat adhesive hybrid joint dengan parameter desain penelitian ini mampu mengutilisasi kemampuan adhesive menyerap energi. Maka dapat disimpulkan, sambungan Battery Pack sedikit lebih kuat dibandingkan sambungan mounting hanya dengan baut.
=======================================================================================================
Impact Load on the Fin Komodo battery pack will result in damage to the battery pack installation on the vehicle structure. The existing design has the risk of being easily detached if given an impact load at a low speed. The safety of this joint can be increased by adding a material that dissipates impact energy, namely adhesive. This author proposes a hybrid adhesive joint to be installed to the Fin Komodo battery pack to absorb impact energy so as to reduce damage to the joint.
This study uses the finite element method to observe the energy absorption of the impact load on the pack connection. Thickness, adhesive type and impact speed will be the variables of this research. This research method uses an indenter that refers to the J2464 standard regarding abuse testing on the Battery Pack. The indenter is given the initial speed as the impact load on the Battery Pack. Then the maximum impact energy absorption value that can be received by the mounting will be observed.
Through this research, it was found that there is a relationship between adhesive thickness and Impact energy absorption received by the connection. The thickness of 0.2 mm to 2 mm has a monotonic relationship while at thicknesses of 2 mm to 4 mm it has a decreasing monotonic relationship. The highest energy absorption occurs in Epoxy 3501-6 with a thickness of 2 mm where this adhesive has the lowest modulus value compared to other adhesives used. There is an increase in the maximum speed of the impactor by 16 %. The implication of this research is that there is a hybrid joint with the design parameters of this study able to utilize the adhesive's ability to absorb energy. That said, the Battery Pack connection is slightly stronger than the bolt-only connection.
