Abstract

Student Formula Japan (SFJ) adalah bagian dari Formula Student of Automotive Engineering (FSAE) region Asia wilayah Jepang yang dimulai sejak tahun 2003 dengan tema Monozukuri yaitu menantang mahasiswa untuk membangun sebuah mobil balap yang terbaik dari berbagai aspek. Kompetisi tersebut dibagi menjadi 2 event yaitu static event terdiri dari design report, cost report and manufacturing, dan business presentation serta dynamic event terdiri dari acceleration, skidpad, autocross, endurance and efficiency. Permasalahan yang dialami mobil Sapuangin Speed adalah kemampuan maneuvability mobil pada event skidpad sehingga perlu dilakukan penelitian lebih lanjut untuk mendapatkan rancangan mobil yang terbaik pada event tersebut sehingga tujuan dari penelitian ini adalah melakukan analisa kestabilan arah mobil Sapuangin Speed VI sehingga meningkatkan kecepatan mobil pada skidpad event Student Formula Japan. Metode penelitian adalah simulasi pemodelan mobil menggunakan software Matlab Simscape-Multibody. Parameter mobil Sapuangin Speed VI disesuaikan pada data spesifikasi mobil yang sudah ditentukan oleh divisi Vehicle Dynamic. Tahapan penelitian adalah melakukan simulasi menggunakan software Matlab SimscapeMultibody dengan input yang diberikan adalah torsi di roda belakang dan sudut belok roda dengan travel rack steering kemudian menganalisa hasil simulasi dan mengganti parameter-parameter yang sudah ditentukan untuk mendapatkan rekomendasi desain yang terbaik. Hasil yang diperoleh berupa posisi lateral dan longitudinal kendaraan untuk melihat kestabilan arah understeer/oversteer, kecepatan, yaw rate, dan tire load yang ditampilkan dalam bentuk gambar dan grafik. Hasil dari penelitian berupa rekomendasi desain terbaik seperti 50: 50 untuk variasi posisi titik berat, 1525 mm untuk variasi wheelbase, 290 mm untuk variasi tinggi center of gravity, 30000 N/mm untuk nilai kekakuan pegas depan dan 52000 N/mm untuk nilai kekakuan pegas belakang.

Student Formula Japan (SFJ) is part of Formula Student of Automotive Engineering (FSAE) Japan region started in 2003 with Monozukuri theme which is challenge students to build the best race car from various aspects. This competition is divided into 2 event, static event consist of design report, cost report and manufacturing, business presentation and dynamic event which consist of acceleration, skidpad, autocross, endurance and efficiency. The problem of Sapuangin Speed car is it’s maneuveraability at skidpad event so it is necessary to conduct a research to get the best car design at that event so the purpose of this research is doing an analysis about stability of Sapuangin Speed VI direction so it could increase the car speed on skidpad event Student Formula Japan. Research method is doing a simulation of car modelling with Matlab Simscape-Multibody software. Sapuangin Speed VI car parameters is adjusted to the car specification data which is determined by Vehicle Dynamic division. Research steps are doing simulation with Matlab Simscape-Multibody software with the input given are rear wheel torque and turning angle of the wheel with travel rack steering, then analyze the simulation result and change the determined parameters to get the best design for a recommendation. The results obtained are lateral and longitudinal car position to see understeer/oversteer stability direction, velocity, yaw rate, and tire load displayed in pictures and graphics. The research results are shown as the best design recommendation, 50: 50 for position of center of gravity variation, 1525 mm for wheelbase variation, 290 mm for center of gravity height variation, 30000 N/mm for front spring stiffness and 52000 N/mm for rear spring stiffness.
