Abstract

TEKNOFEST: International Efficiency Challenge Electric Vehicle (IECEV) adalah salah satu kompetisi mobil listrik hemat energi tahunan yang diadakan oleh Scientific and Technological Research Council of Turkey (TÜBITAK). Untuk pertama kalinya, Tim Nogogeni Institut Teknologi Sepuluh Nopember (ITS) berpartisipasi pada kompetisi tersebut. Tim Nogogeni ITS pun merancang mobil listik dengan nama Nogogeni Double Seat. Regulasi IECEV menetapkan dimensi frame pada mobil listrik yang akan dilombakan serta menetapkan penggunaan material baja atau paduannya yang memiliki yield strength minimal sebesar 200 MPa untuk bagian roll bar dan roll cage dari frame. Penelitian ini akan mengacu pada analisis berupa simulasi pada frame mobil Nogogeni Double Seat. Frame mobil Nogogeni Double Seat menggunakan dua material berbeda yaitu ASTM A53-B untuk roll bar & roll cage dan Alumunium 6061 untuk chassis. Berdasarkan dimensi dan material dari frame yang sudah dirancang oleh Nogogeni ITS, analisis yang dilakukan berupa perhitungan kekuatan frame dari beban dinamis mobil, yaitu keadaan mobil saat berakselerasi, pengereman, dan berbelok. Selanjutnya, dilakukan simulasi dengan software metode elemen hingga. Dari hasil perhitungan dan simulasi diperoleh nilai tegangan kombinasi maksimum sebesar 45,023 MPa pada kondisi akselerasi, 49,904 MPa pada kondisi pengereman, serta 45,266 MPa pada kondisi berbelok. Total deformasi yang diperoleh sebesar 0,3 mm pada kondisi akselerasi, 0,41 mm pada kondisi pengereman, dan 1,05 mm pada kondisi berbelok. Nilai safety factor yang diperoleh pada kondisi akselerasi sebesar 4,09; kondisi pengereman sebesar 3,69; dan kondisi berbelok sebesar 4,06.

TEKNOFEST: International Efficiency Challenge Electric Vehicle (IECEV) is one of the annual energy-efficient electric car competitions held by the Scientific and Technological Research Council of Turkey (TÜBITAK). For the first time, the Nogogeni Team of the Sepuluh Nopember Institute of Technology (ITS) participated in the competition. The ITS Nogogeni team also designed an electric car with the name Nogogeni Double Seat. The IECEV regulations define frame dimensions for electric cars to be contested and stipulate the use of steel or alloy materials that have a minimum yield strength of 200 MPa for the roll bar and roll cage parts of the frame. This research will refer to the analysis in the form of a simulation on the Nogogeni Double Seat car frame. The Nogogeni Double Seat car frame uses two different materials namely ASTM A53-B for the roll bar & roll cage and Aluminum 6061 for the chassis. Based on the dimensions and material of the frame that has been designed by Nogogeni ITS, the analysis is carried out in the form of calculating the strength of the frame from the dynamic load of the car, namely the state of the car when accelerating, braking and turning. Furthermore, simulations were carried out with the finite element method software. From the calculation and simulation results, the maximum combined stress value is 45.023 MPa in acceleration conditions, 49.904 MPa in braking conditions, and 45.266 MPa in turning conditions. The total deformation obtained is 0.3 mm in acceleration conditions, 0.41 mm in braking conditions, and 1.05 mm in turning conditions. The safety factor value obtained in accelerated conditions is 4.09; braking conditions of 3.69; and turning conditions of 4.06.
