Abstract

Regenerative Swing Arm (RSA) merupakan sistem suspensi regeneratif yang ditujukan untuk kendaraan listrik roda dua (e-scooter) yang memanfaatkan energi buangan dari getaran lengan ayun. Perlu diketahui bagaimana hubungan antara parameter rancang bangun pemasangan RSA terhadap kinerjanya. Pada penelitian ini, dilakukan eksperimen untuk mengetahui pengaruh variasi posisi suspensi dari RSA pada pemasangan di skuter listrik VOLTA 302 terhadap energi bangkitan yang dihasilkan dan kenyamanan berkendara. Penelitian diawali dengan menambahkan 3 buah bantalan bawah peredam kejut pada RSA sebagai variasi posisi suspensi dengan jarak antar pusat bantalan sebesar 5 cm. Kemudian dilakukan pemasangan RSA pada e-scooter VOLTA 302. Dilakukan uji jalan melewati polisi tidur pada jalan paving blok dengan kecepatan 25 km/h dan dikendarai oleh 1 orang dengan massa 80 kg. Selama uji jalan, dilakukan pengukuran tegangan bangkitan RSA dan juga pengukuran percepatan vertikal pada bagian bawah jok pada posisi di bawah tulang duduk pengendara menggunakan akselerometer untuk mengetahui tingkat kenyamanan berkendara. Analisis kenyamanan dilakukan berdasarkan nilai akar-akar kuadrat (Root Mean Square/RMS) dari percepatan vertikal hasil pengukuran menggunakan standar kenyamanan ISO 2631. Telah dilakukan rancang bangun pemasangan Regenerative Swing Arm (RSA) pada e�scooter VOLTA 302 yang dapat menyerap energi saat siklus kompresi maupun ekspansi sehingga dapat menghasilkan energi bangkitan yang lebih berkelanjutan. Regenerative Swing Arm (RSA) pada skuter listrik VOLTA 302 mampu menghasilkan tegangan maksimum pada variasi posisi suspensi A saat melalui polisi tidur pada kecepatan 25 km/h sebesar 57,589 mV dengan daya bangkitan maksimum sebesar 551,9 µW. Lalu untuk nilai tegangan pada posisi suspensi B sebesar 53,797 mV dengan daya bangkitan sebesar 285,7 µW dan untuk nilai tegangan pada posisi suspensi C sebesar 32,75 mV dengan daya bangkitan sebesar 152,1 µW.Berdasarkan respon percepatan vertikal, semakin kecil sudut suspensi RSA, maka semakin baik tingkat kenyamanan berkendara karena percepatan vertikal kendaraan menjadi semakin kecil. Namun, pada semua variasi posisi suspensi yang diberikan yaitu posisi A dengan sudut 90ᵒ, posisi B dengan sudut 66,24ᵒ, dan posisi C dengan sudut 61,8ᵒ, tidak ada keluhan kenyamanan karena nilai RMS percepatan vertikalnya jauh di bawah 0,315 m/s² yang merupakan batas kategori “tidak ada keluhan” sehingga semua variasi posisi baik untuk digunakan menurut standar ISO 2631

Regenerative Swing Arm (RSA) is a regenerative suspension system intended for two�wheeled electric vehicles (e-scooters) that utilizes the energy released from the swing arm vibration. It is necessary to know how the relationship between the design parameters of the RSA installation and its performance. In this study, an experiment was conducted to determine the effect of variations in the suspension position of the RSA on the installation of the VOLTA 302 electric scooter on the generated energy and driving comfort. The study began by adding 3 shock absorbers under the RSA as a variation of the suspension position with a distance between the centers of the bearings of 5 cm. Then the RSA was installed on the VOLTA 302 e-scooter. A road test was carried out through speed bumps on a paving block road at a speed of 25 km/h and driven by 1 person with a mass of 80 kg. During the road test, the RSA generation voltage was measured as well as the vertical acceleration measurement at the bottom of the seat at the position below the rider's spine using an accelerometer to determine the level of driving comfort. Comfort analysis was carried out based on the value of the square roots (Root Mean Square/RMS) of the vertical acceleration measured using the ISO 2631 comfort standard. The design of the installation of the Regenerative Swing Arm (RSA) on the VOLTA 302 e-scooter has been carried out which can absorb energy during compression and expansion cycles so that it can produce more sustainable energy generation. The Regenerative Swing Arm (RSA) on the VOLTA 302 electric scooter is capable of producing a maximum voltage at the variation of the suspension position A when passing through speed bumps at 25 km/h of 57,589 mV with a maximum generation power of 551.9 µW. Then for the value of the voltage at the suspension position B of 53.797 mV with a generation power of 285.7 µW and for the value of the voltage at the suspension position C of 32.75 mV with a generation power of 152.1 µW. Based on the vertical acceleration response, the smaller the RSA suspension angle, the better the level of driving comfort because the vertical acceleration of the vehicle becomes smaller. However, in all variations of the suspension position given, namely position A with an angle of 90ᵒ, position B with an angle of 66.24ᵒ, and position C with an angle of 61.8ᵒ, there are no comfort complaints because the RMS value of vertical acceleration is far below the 0.315 m/s² which is the limit of the “no complaints” category so that all position variations are good to use according to the ISO 2631 standard
