ABSTRAK

Menyadari besarnya energi terbuang pada gerak translasi dari suspensi kendaraan tentunya dibutuhkan suatu alat yang mampu memanen energi terbuang tersebut. Pada penelitian ini dikembangkan sistem suspensi yang disebut Hydraulic Motor Regenerative Shock Absorber yang mampu memanfaatkan energi terbuang untuk diubah ke dalam bentuk energi listrik. Penelitian ini diawali dengan mendesain prototype hydraulic Motor regenerative shock absorber HMRSA. Hasil desain HMRSA tersebut kemudian disimulasikan dengan software simulink matlab. Selanjutnya rancang bangun prototype hydraulic motor regenerative shock absorber dilakukan untuk diuji karakteristik respon getaranya dengan variasi frekuensi dan tahanan listrik generator. Terakhir hasil simulasi divalidasi terhadap hasil eksperimen untuk melihat besaran error yang terjadi. Dari pengujian statis didapatkan nilai koefisien redaman HMRSA pada tahanan listrik sebesar 6 ohm 12 ohm dan 18 ohm masing masing sebesar 11.108 Nms 11.044 N.ms dan 10.704 N.ms. Pengujian dinamis pada variasi frekuensi eksitasi 1.4 Hz 1.75 Hz 2 Hz dan variasi tahanan listrik menghasilkan nilai rms percepatan massa sprung dibawah 2 ms2. Hal ini menunjukan bahwa HMRSA mampu menjaga kenyamanan berkendara pada frekuensi dan amplitudo eksitasi tersebut. Hasil validasi simulasi terhadap eksperimen menunjukan tren percepatan massa sprungnya hampir sama dengan kisaran error rms percepatan massa sprung sebesar 16 45 . Daya yang dihasilkan HMRSA pada frekuensi 1.4 Hz 1.75 Hz dan 2 Hz berkisar antara 0.024 watt sampai 1.1078 watt.


ABSTRACT

Most of the energy from translation motion of suspension is wasted that is all to be need a mechanism that can harvest the wasted energy. This research is to develop a system of suspension Hydraulic Motor Regenartive Shock Absorber that is can recovery wasted energy to convert in electrical energy. This research is started to design prototype Hydraulic Motor Regenerative Shock Absorber HMRSA. The simulation based on design of HMRSA using software Simulink matlab. The characteristic of prototype hydraulic motor regenerative shock absorber is to be tested with variation of frequency and variation electrical resistance. The validation of simulation and experiment to be done to get the number of eror. From this study it is found that the coefficient of damping HMRSA with resistance 6 ohm 12 ohm dan 18 ohm each as 11.108 Nms 11.044 N.ms and 10.704 N.ms. The acceleration at variation frequency 1.4 Hz 1.75 Hz and variation electric resistance each as less than 0.8 ms2. That is mean the HMRSA able to keep comfortable of driver at thats excitation frequency. The validation of simulation and experiment show the same tren sprung ass acceleration with error rms sprung mass acceleration as 16 45 . The power ouput HMRSA at frequency 1.4 Hz 1.75 Hz dan 2 Hz about 0.024 watt untill 1.1078 watt.
