Abstract
Sistem suspensi kendaraan terdiri dari sistem massa, pegas, peredam. Shock absorber merupakan bagian utama yang berfungsi meredam getaran yang ditransmisikan dari sumber getaran, pegas berfungsi untuk memberikan kekakuan pada sistem dan mentransformasi energi kinetik menjadi energi potensial. Banyak peneliti mengembangkan tentang hydraulic regenerative suspension, tipe desain yang ada pada saat ini, yaitu Linear Electromagnetic Shock Absorber, Rack Pinion Electromagnetic Suspension, Ball Screw Electromagnetic Suspension, Hydraulic Electromagnetic Suspension. Pengembangan suspensi regenerative harus memperhatikan dua aspek, yaitu kemampuan sistem meregenerasi energi dan kenyamanan yang diberikan. Pada penelitian ini sistem kerja Hidro-Magneto-electric-regenerative shock absorber (HMERSA) dengan 4 input dan single output. Langkah pertama, mensimulasikan aliran fluida kesetiap selinder hidrolik agar alirannya searah. Kemudian memberikan inputan pada ke empat selinder hidrolik dengan 4 variasi input dan single output. Hasil yang diamati adalah Kecepatan putaran motor hidrolik variasi 1 dari 0 sampai 2.33 detik adalah 140 Rpm, variasi 2 dari 0 sampai 0,63 detik adalah 41,4 Rpm, variasi 3 dari 0 sampai 1,2 detik adalah 140 putaran dan variasi ke 4 dari 0 sampai 0,63 detik adalah 8 putaran. Semakin sering pergerakan selinder hidrolik semakin tinggi putaran motor hidrolik yang dihasilkan. Gaya redam yang diperoleh dari variasi 1 dengan frekuensi 2 Hz sebesar -1004,84 Nm, voltase 58,36 volt, arus 1,98 ampere, dan daya listrik 115,86 watt. Variasi 2 gaya redam dengan frekuensi 2 Hz sebesar -812,43 Nm, voltase 43,77 Hz, arus 1,48 ampere, dan daya listrik 65,17 watt. Variasi 3 gaya redam dengan frekuensi 2 Hz -620,04 Nm, voltase 29,18 volt, arus 0,99 ampere dan daya listrik 20,43 watt. Variasi 4 gaya redam dengan frekuensi 2 Hz -427,64 Nm, voltase 14,59 volt, arus 0,49 ampere dan daya listrik 7,24 watt. Semakin besar frekuensi yang diberikan semakin besar daya redam yang dihasilkan pada setiap selinder hidrolik

Vehicle suspension system consists of a system of masses, springs, dampers. Shock absorber is the main part that serves to reduce vibration transmitted from the vibration source, spring serves to provide rigidity to the system and transform kinetic energy into potential energy. Many researchers develop on hydraulic regenerative suspension, the type of design that exist at the moment, namely Linear Electromagnetic Shock Absorber, Rack Pinion Electromagnetic Suspension, Ball Screw Electromagnetic Suspension, Hydraulic Electromagnetic Suspension. The development of regenerative suspension should pay attention to two aspects, namely the system's ability to regenerate energy and comfort provided. In this research work systems Hydro-Magneto-electric-shock absorber regenerative (HMERSA) with 4 inputs and single output. The first step, simulate fluid flow to the rest of the hydraulic cylinder so that the flow is unidirectional. Then provide input to the hydraulic cylinder to four with 4 variations of input and single output. The results observed are hydraulic motor rotation speed variation 1 from 0 to 2:33 seconds is 140 rpm, variation 2 from 0 to 0.63 seconds is 41.4 rpm, variation 3 from 0 to 1.2 seconds is 140 rounds and variation 4 from 0 to 0.63 seconds is 8 rpm. The more often the movement of the hydraulic cylinder the higher the resulting hydraulic motor rotation. Style damping obtained from variation 1 with a frequency of 2 Hz for -1004.84 Nm, voltage of 58.36 volts, the current is 1.98 amperes, and 115.86 watts of electrical power. Variation 2 damping force with a frequency of 2 Hz at -812.43 Nm, 43.77 Hz voltage, current of 1.48 amperes and 65.17 watts of electrical power. Variation 3 damping force with a frequency of 2 Hz -620.04 Nm, voltage of 29.18 volts, the current is 0.99 amperes and 20.43 watts of electrical power. Variation 4 damping force with a frequency of 2 Hz -427.64 Nm, voltage of 14.59 volts, the current is 0.49 amperes and 7.24 watts of electrical power. The greater the frequency given greater damping power generated at each hydraulic cylinder.
