Abstract

Pada saat ini kebutuhan energi dari fossil fuel cenderung mengalami peningkatan pada tiap tahunnya.. Fossil fuel merupakan energi yang tidak dapat diperbaharui, sedangkan kebutuhan terhadap bahan bakar tersebut masih cenderung meningkat, sehingga hal ini berpotensi menurunkan persediaan fossil fuel seiring bertambahnya waktu oleh karena itu diperlukaan sumber energi alternatif yang berguna untuk mengurangi konsumsi energi fossil fuel. Berbagai sumber energi alternatif telah banyak dikembangkan diantaranya adalah Hydraulic Electro Mechanic Shock Absorber (HEMSA) Pada penelitian ini, tertuju pada peningkatan kinerja sistem transmisi daya Hydraulic Electro Mechanic Shock Absorber (HEMSA) generasi keempat dengan dua selang kompresi satu selang ekspansi untuk rasio silinder 30 mm : 40 mm dengan pembebanan akumulator akibat eksitasi impuls dan periodik pada tingkat variasi yang lebih kuantitatif. Pengukuran energi bangkitan dilakukan dengan menggunakan quarter car suspension test rig. Pengujian dialkukan dengan memasang Hydraulic Electro Mechanic Shock Absorber (HEMSA) ini pada alat tersebut yang kemudian akan diberikan massa uji yang merepresentasikan ¼ dari kendaraan (city car). Dari penelitian ini didapatkan nilai konstanta redaman HEMSA dua selang kompresi satu ekspansi tanpa pembebanan sebesar 595.035 Ns/m. Energi bangkitan HEMSA dua selang kompresi satu ekspansi, ketika frekuensi 1.3Hz yaitu sebesar 0.37 Watt, ketika frekuensi 1.5 Hz ialah 0.64 Watt, dan ketika frekuensi 1,7 Hz sebesar 2.14 Watt. ========================================================================================================= At this moment, the energy requirement of fossil fuel tend to increase in every year. Fossil fuel is non-renewable energy, meanwhile that requirement fuel is still grow up, thus based on this situation, it can reduce the allocation of fossil fuel and need the alternative energy sources that can be used for reduce consumption of fossil fuel energy. Many kind of the alternative energy sources are more developing likes Hydraulic Electro Mechanic Shock Absorber (HEMSA). In this research, focused on improving the performance of the fourth generation of power transmission system Hydraulic Electro Mechanic Shock Absorber (HEMSA) that consist of two compression hose and one expansion hose for 30mm : 40mm ratio of cylinder with accumulator charging that is caused by impulse excitation and periodic on more quantitative level variation. Measurement of evocation energy is done by using quarter car suspension test rig. Testing is done by installing this Hydraulic Electro Mechanic Shock Absorber (HEMSA) on that instrument and then it will be given the trial period that represent ¼ of car (city car). From this research, it has been gotten the damping constant value of HEMSA that consist of two compression hose and one expansion hose without imposition of 595.035 Ns/m. The evocation energy of HEMSA that consist of two compression hose to expansion is happen when. on the frequency of 1.3Hz is 0,37 Watt, on the frequency of 1.5Hz is 0.64 Watt, and on the frequency of 1,7Hz is 2.14 Watt.
