Abstract
Nogogeni Urban Ethanol merupakan mobil hemat energi berkonsep city car yang menggunakan ethanol sebagai bahan bakarnya. Mobil ini diciptakan oleh mahasiswa Institut Teknologi Sepuluh Nopember untuk mengikuti event Kontes Mobil Hemat Energi (KMHE) yang diselenggarakan oleh Kemenristekdikti. Salah satu aspek tolak ukur untuk menunjang mobil yang hemat bahan bakar adalah faktor berat kendaraan. Bagian konstruksi chassis menjadi penyumbang terbesar dalam mempengaruhi berat kendaraan. Elemen dari chassis tersebut ialah rangka dan poros. Pada laporan tugas akhir ini akan membahas tentang perhitungan mengenai distribusi gaya-gaya yang bekerja pada chassis mobil Nogogeni Urban Ethanol dan memastikan keamanan balok hollow dengan dimensi 1:2 inchi berbahan aluminium 6061-T6. Sedangkan perhitungan poros penggerak roda belakang (Axle Shaft) untuk menentukan diameter minimum poros yang optimal. Dari hasil perhitungan didapatkan tegangan tarik 0,563 MPa ≤ |σcyp| tegangan geser sebesar 2,944 MPa ≤ |σsyp|, tegangan bending 30,184 MPa ≤ |σbyp|, dan tegangan total 30,887 MPa ≤ ( |σsyp|=50,6 MPa) sehingga chassis masih aman. Sedangkan hasil perhitungan poros penggerak roda belakang didapatkan diameter minimum poros pejal menggunakan bahan AISI 4140 adalah 17,92 mm sedangkan poros berlubang dengan bahan AISI 1010 adalah 23,868 mm.
===========================================================================================================================
Nogogeni Urban Ethanol is an energy-efficient car with a city car concept that uses ethanol as its fuel. This car was created by students of the Sepuluh Nopember Institute of Technology to attend Kontes Mobil Hemat Energi (KMHE) event organized by the Ministry of Research, Technology and Higher Education. One aspect of benchmarks to support fuel-efficient cars is the weight factor of the vehicle. The chassis construction section is the biggest contributor to the weight of the vehicle. The elements of the chassis are the frame and shaft. In this final project report will discuss about the calculation of the distribution of forces acting on the Nogogeni Urban Ethanol car chassis and ensure the safety of hollow beams with dimensions of 1:2 inch made from aluminum 6061-T6. While the calculation of the rear axle shaft to determine the optimal minimum shaft diameter. From the calculation results, the tensile stress is equal to 0,563 MPa ≤ |σcyp|, shear stress 2,944 MPa ≤ |σsyp|, bending stress 30,184 MPa ≤ |σbyp|, and total stress 30,887 MPa ≤ ( |σsyp|= 50,6 MPa) so the chassis is still safe. While the calculation result of the rear axle shaft is obtained the minimum diameter of solid shaft using AISI 4140 material is 17,92 mm while the hollow shaft with AISI 1010 material is 23,868 mm.
