Abstract

Perkembangan teknologi sistem suspensi pada dunia otomotif sangat pesat khususnya teknologi shock absorber (damper). Sistem suspensi yang umum diterapkan pada kendaraan saat ini adalah sistem suspensi dimana media damper yang digunakan adalah fluida. Beberapa kelemahan media fluida diantaranya sering terdapat kebocoran, kerusakan pada katup dan sebagainya. Dari permasalahan tersebut dibuat damper magnet dengan memanfaatkan gaya magnet yang ditimbulkan oleh kumparan koil. Nilai redaman (C) teoritis pada perancangan untuk arus 0.13 A, 0.26 A, 0.39 A dan 0.52 A adalah 5.49 N.sedm; 6. 70 N.sedm; 7. 75 N.sec/m dan 9.44 N.sec/m. Sedangkan redaman (C) pengujian logaritmik decreament pada arus 0.13 A, 0.26 A, 0.39 A dan 0.52 A Pada frekuensi natural19 radlsec adalah 4.97 N.sedm; 6.42 N.sedm; 7.41 N.sec/m dan 8.44 N.sedm. Sedangkan padafrekuensi natural 16,9 rad/sec adalah 4,25 N.sec/m; 5,26 N.sec/m; 6, 71 N.sedm dan 8,96 N.sedm. Sehingga nilai redaman tertinggi dicapai pada arus 0,52 A dengan ni/ai redaman 8,98 N.sedm, hanya padafrekuensi natural 16,9 rad/sec. Hasil perancangan dan pengujian memiliki nilai error yang berkisar 7 % sampai 16%. Untuk perancangan yang lebih baik · maka perlu penelitian yang lebih lanjut

he development of suspension system technology in the automotive world is very rapid, especially shock absorber (damper) technology. The suspension system commonly applied to vehicles today is a suspension system where the damper media used is fluid. Some weaknesses of fluid media include frequent leaks, damage to valves and so on. From these problems, a magnetic damper is made by utilizing the magnetic force generated by the coil coil. The theoretical damping (C) value in the design for currents of 0.13 A, 0.26 A, 0.39 A and 0.52 A is 5.49 N.sedm; 6. 70 N.sedm; 7. 75 N.sec/m and 9.44 N.sec/m. While the damping (C) of the logarithmic decreament test at currents of 0.13 A, 0.26 A, 0.39 A and 0.52 A at a natural frequency of 19 radlsec is 4.97 N.sedm; 6.42 N.sedm; 7.41 N.sec/m and 8.44 N.sedm. While at a natural frequency of 16.9 rad/sec it is 4.25 N.sec/m; 5.26 N.sec/m; 6.71 N.sedm and 8.96 N.sedm. So the highest damping value is achieved at a current of 0.52 A with a damping value of 8.98 N.sedm, only at a natural frequency of 16.9 rad/sec. The design and testing results have an error value ranging from 7% to 16%. For better design, further research is needed
