Abstract

Getaran yang ditimbulkan kendaraan pada saat berkendara akan mempengaruhi kenyamanan dari pengemudi dan penumpangnya. Sistem suspensi membuat kendaraan yang melintasi permukaan jalan yang tidak rata menerima getaran bodi kendaraan yang minimal. Perkembangan suspensi saat ini semakin pesat salah satunya suspensi semi-aktif. Sistem suspensi dibagi menjadi tiga jenis, yaitu sistem suspensi pasif, sistem suspensi semi-aktif, dan sistem suspensi aktif. Science Techno Park (STP) Otomotif ITS telah membangun kendaraan roda tiga untuk mengangkut sayur bernama E-KEVIK dimana masih menggunakan suspensi pasif. Pemilihan suspensi semi-aktif pada sistem suspensi salah satunya untuk meningkatkan kenyamanan bagi pengendara. Penelitian ini menggunakan electric linear actuator dan sistem kontrol elektriknya terdiri dari mikrokontroler arduino nano, accelerometer sensor, motor driver. Metodologi penelitian diawali dengan studi literatur mengenai perkembangan sistem suspensi semi-aktif, observasi lapangan mengenai parameter kendaraan roda tiga (E-KEVIK), perancangan sistem suspensi semi-aktif, proses pembuatan kontroler, perakitan sistem kontrol pada suspensi, serta pengujian sistem suspensi semi-aktif. Pengujian dilakukan pada gangguan jalan speed bump, speed hump, dan speed table dengan kecepatan 30 km/jam. Nilai RMS yang dihasilkan oleh sistem suspensi semi-aktif berturut – turut adalah 0,158 m/s2, 0,147 m/s2, dan 0,362 m/s2, dapat disimpulkan bahwa nilai tersebut termasuk ke dalam kategori “Sangat Nyaman” ketika melewati gangguan speed bump dan speed hump dikarenakan nilai RMS < 0,315 m/s2, dan kategori “Nyaman” ketika melewati gangguan speed table dikarenakan nilai RMS 0,315 – 0,63 m/s2 berdasarkan standar ISO 2631. Hal ini menunjukkan kerja sistem suspensi semi-aktif efektif dan memiliki peforma yang baik.
============================================================
The vibration caused by the vehicle during driving will affect the comfort of the driver and passengers. The suspension system makes vehicles crossing uneven road surfaces receive minimal vehicle body vibration. The development of suspensions is currently increasing rapidly, one of which is semi-active suspension. Suspension systems are divided into three types, namely passive suspension systems, semi-active suspension systems, and active suspension systems. The ITS Automotive Science Techno Park (STP) has built a three-wheeled vehicle for transporting vegetables called E-KEVIK which still uses a passive suspension. The choice of semi-active suspension in the suspension system is to increase comfort for the driver. This research uses an electric linear actuator and its electrical control system consists of an arduino nano microcontroller, accelerometer sensor, motor driver. The research methodology begins with a literature study on the development of semi-active suspension systems, field observations of three-wheeled vehicle parameters (E-KEVIK), design of semi-active suspension systems, controller manufacturing processes, assembly of control systems on suspensions, and testing of semi-active suspension systems. Tests were carried out on speed bump, speed hump, and speed table road disturbances with a speed of 30 km/hour. The RMS values produced by the semi-active suspension system are 0.158 m/s2, 0.147 m/s2, and 0.362 m/s2 respectively, it can be concluded that these values fall into the “Very Comfortable” category when passing through speed bump and speed hump disturbances due to RMS values < 0.315 m/s2, and ‘Comfortable’ category when passing through speed table disturbances due to RMS values of 0.315 - 0.63 m/s2 based on ISO 2631 standards. This shows that the semi-active suspension system works effectively and has good performance
