Abstract
Formula Student Society of Automotive Engineer (FSAE) adalah sebuah kompetisi
tahunan yang diadakan oleh Society of Automotive Engineer (SAE). Pada kompetisi ini,
diadakan dua jenis event, yaitu static event dan dynamic event. Pada dynamic event, rata-rata
raihan waktu pada acceleration adalah 6,394 detik dan Anargya Mark 3 hanya mampu meraih
7 detik. Salah satu penyebab mobil Mark 3 memiliki performa dibawah rata-rata adalah massa
yang terlalu besar.
Drivetrain pada mobil mengacu pada komponen yang berfungsi untuk menyalurkan
power dari mesin atau motor listrik ke roda. Pada mobil formula student Anargya ITS Mark 3,
komponen drivetrain memiliki massa total 39 kg padahal pada rata-rata massa komponen
drivetrain termasuk dengan motor listrik berkisar antara 19,5 sampai dengan 23 kg. Melalui
pernyataan tersebut, dapat disimpulkan bahwa salah satu faktor mengapa mobil formula student
Anargya ITS Mark 3 masih memiliki kemampuan dibawah rata-rata adalah massa komponen
drivetrain yang terlalu besar. Namun, hal ini bisa diatasi dengan melakukan optimasi pada
komponen drivetrain, seperti mechanical packaging atau mount.
Pada penelitian ini akan digunakan metode Quality Function Deployment (QFD)
sebagai pendekatan untuk mendesain dan Finite Element Analysis (FEA) untuk menganalisis
struktur dari desain differential mounts saat menerima beban. Metode QFD digunakan pada
penelitian ini agar dilakukan pendekatan pada proses pendesainan yang berfokus pada Voice Of
Customer (VOC). Sedangkan FEA akan digunakan untuk menganalsis model yang berguna
untuk memprediksi bagaimana reaksi differential mounts saat berada dalam kondisi
pembebanan.
Hasil dari penelitian ini adalah dibuatkan tiga desain yang memenuhi hasil pendekatan
QFD dan desain kriteria dari differential mounts. Melalui analisis stiffness to weight ratio
didapatkan rekomendasi desain terpilih yaitu desain kedua dengan massa 0,511 kg, factor of
safety 2,38, stiffness 4.407,89 N/mm dan stiffness to weight ratio 8.628 N/mm/kg.
==================================================================================================
Formula Student Society of Automotive Engineer (FSAE) is an annual competition held
by the Society of Automotive Engineer (SAE). In this competition, two types of events are held,
namely static events and dynamic events. In the dynamic event, the average time achievement
in acceleration is 6,394 seconds and Anargya Mark 3 formula student car testing results were
only able to achieve 7 seconds. One of the reasons why the Mark 3 car has below-average
performance is that the mass is too large.
The drivetrain in a car refers to a component that channels power from the engine or
electric motor to the wheels. In the Anargya ITS Mark 3 formula student car, the drivetrain
component has a total mass of 39 kg. In contrast, on average the mass of the drivetrain
component including the electric motor ranges from 19,5 to 23 kg. Through this statement, it
can be concluded that one of the factors why the Anargya ITS Mark 3 student formula car still
has below-average capabilities is the mass of drivetrain components that are too large.
However, optimizing drivetrain components, such as mechanical packaging or mounts, can
overcome this.
In this research, the Quality Function Deployment (QFD) method will be used to design
and Finite Element Analysis (FEA) to analyze the structure of the differential mounts design
when receiving loads. The QFD method is used in this research to approach the design process
that focuses on the Voice Of Customer (VOC). Meanwhile, FEA will be used to analyze a
useful model for predicting how the differential mounts will react under loading conditions.
This research results in the creation of three designs that meet the results of the QFD
approach and the design criteria of the differential mounts. Through the stiffness-to-weight ratio
analysis, the selected design recommendation is the second design with a mass of 0.511 kg,
safety factor of 2,38, stiffness of 4.407,89 N/mm, and stiffness-to-weight ratio of 8.628
N/mm/kg.
