ANALISIS AERODINAMIKA UNTUK DESAIN MOBIL LISTRIK JENIS KARGO MINI
Abstrak
Sebagai upaya untuk memperluas pengembangan mobil listrik, salah satu langkahnya adalah merancang desain body mobil listrik yang aerodinamis. Desain body yang aerodinamis dapat mengurangi gaya hambat yang terjadi pada kendaraan, sehingga akan menghemat penggunaan energi bagi kendaraan. Hal yang perlu diperhatikan dalam desain aerodinamis yaitu nilai koefisien drag (Cd), semakin kecil nilai Cd maka akan semakin meningkatkan efisiensi energi dan kinerja kendaraan secara keseluruhan. Oleh karena itu, penelitian ini bertujuan untuk merancang sebuah body mobil listrik jenis kargo mini yang aerodinamis yang nantinya desain tersebut dapat dijadikan salah satu desain rujukan dalam mendesain kendaraan listrik jenis kargo mini. Simulasi dilakukan menggunakan perangkat lunak ansys fluent 2023 R1 dengan metode computational fluid dynamics (CFD). Validasi awal dilakukan menggunakan desain Ahmed body. Simulasi dilakukan dengan variasi kecepatan 20 km/h, 30 km/h, 40 km/h, 50 km/h, dan 60 km/h. Hasil penelitian menunjukkan bahwa nilai Cd terendah terjadi pada kecepatan 60 km/h yaitu sebesar 0,458. Dengan demikian, pada kecepatan 60 km/h mobil listrik jenis kargo mini akan memiliki efisiensi energi dan kinerja kendaraan kendaraan lebih baik dibandingkan pada kecepatan lain.
