Abstract

Jumlah kendaraan dari tahun ke tahun mengalami peningkatan, terutama pada jenis sepeda motor dimana mengalami peningkatan sebesar 0,53% pada tahun 2021 berdasarkan data Badan Pusat Statistika. Pada umumnya jenis kendaraan dibagi kedalam 3 kelompok berdasarkan jalan yang dilalui yaitu untuk jalan raya (sport, cruiser, touring, scooter, underbone, standart), non jalan raya (Motocross, trail, trial), dua medan jalan/dual purpose (Supermoto, adventure touring). Di Indonesia sendiri sudah banyak industri otomotif di bidang sepeda motor dimana setiap industri memiliki spesifikasi dan keunggulan masing-masing. Meskipun kendaraan sepeda motor sudah marak di Indonesia, namun masih banyak daerah-daerah pedalam yang belum memperoleh akomodasi untuk memenuhi kebutuhan sehari hari dikarenakan akses jalan yang ekstrim dan langkanya BBM didaerah tersebut. Untuk mengatasi masalah ini maka kendaraan listrik adalah solusinya, namun kendaraan listrik tersebut harus memiliki daya tahan terutama dalam melewati rute ekstrim.
Pada penelitian kali ini, chassis Trail Kawasaki KLX 150 digunakan sebagai referensi desain chassis E-Trail Bangkit Cenderawasih dalam merakit sepeda motor listrik. Karena adanya perbedaan pusat massa dan aksesbilitas antara komponen ICE (Internal Combustion Engine) dan EV (Electric Vehicle) maka dilakukan analisa terkait kekakuan dengan pembebanan lateral, longitudinal, dan torsional dimana nilai yang diperoleh akan dibandingkan dengan standarisasi chassis sepeda motor. Selanjutnya akan dihitung kekuatan melalui uji impact, kemudian kelelahan sehingga dapat ditentukan umur dari kendaraan dengan pemakaian ekstrim yaitu saat pengereman dan percepatan maksimal. Dari hasil analisa tersebut akan dilakukan optimalisasi pada chassis tersebut.
Dari hasil simulasi kekakuan, kekuatan, dan kelelahan diperoleh nilai kekakuan chassis kedua lebih unggul dibandingkan dengan chassis pertama, dimana chassis kedua telah mencapai nilai standard kekakuan lateral sebesar 1,48 kN/mm, dan longitudinal sebesar 5,076 kN/mm. Untuk nilai safety factor, chassis kedua juga lebih unggul namun tidak terlalu signifikan terhadap chassis pertama, dan dalam uji fatigue, chassis kedua memiliki umur 57,36 tahun, dan chassis pertama memiliki umur 33,96 tahun.
================================================================================================================================
The number of vehicles has increased by years, especially motorcycles, which have increased by 0.53% in 2021 based on data from the Central Statistics Agency. In general, the types of vehicles are divided into 3 groups based on the road traveled, namely for highways (sport, cruiser, touring, scooter, underbone, standart), non-highway (Motocross, trail, trial), two-road terrain / dual purpose (Supermoto, adventure touring). In Indonesia, there are already many automotive industries in the motorcycle sector where each industry has its own specifications and advantages. Even though motorbikes are already widespread in Indonesia, there are still many inland areas that have not received accommodation to meet their daily needs due to extreme road access and the scarcity of fuel in these areas. To overcome this problem, electric vehicles are the solution, but these electric vehicles must have endurance, especially in passing extreme routes.
In this study, the Trail Kawasaki KLX 150 chassis was used as a reference for the Bangkit Cenderawasih E-Trail chassis design in assembling electric motorcycles. Due to differences in the center of mass and accessibility between the ICE (Internal Combustion Engine) and EV (Electric Vehicle) components, an analysis is carried out related to stiffness with lateral, longitudinal and torsional loading where the values obtained will be compared with standardized motorcycle chassis. Next, strength will be calculated through an impact test, then fatigue so that the age of the vehicle with extreme use can be determined, namely when braking and maximum acceleration. From the results of the analysis, optimization of the chassis will be carried out.
From the simulation results of stiffness, strength, and fatigue, the stiffness value of the second chassis is superior to that of the first chassis, where the second chassis has achieved a standard value of lateral stiffness of 1.48 kN/mm and longitudinal stiffness of 5.076 kN/mm. For the value of safety factor, the second chassis is also superior but not too significant to the first chassis, and in the fatigue test, the second chassis has an age of 57.36 years, and the first chassis has an age of 33.96 years.
