Abstract

Sepeda motor yang berkembang di masyarakat massih memiliki spesifikasi yang masih standar seperti suspensi yang masih menggunakan sistem pasif. Sistem suspensi pasif ini tidak bisa beradaptasi dengan perubahan permukaan jalan dikarenakan masih memiliki konstanta pegas dan peredaman yang masih konstan. Dan itu mempengaruhi kenyamanan saat berkendara dikarenakan sistem suspensi kurang mampu mengisolasi getaran pada bodi kendaraan. Oleh karena itu, dikembangkanlah teknologi sistem suspensi semi aktif. Sistem suspensi semi aktif adalah sebuah sistem suspensi yang bisa beradaptasi dengan perubahan permukaan jalan sehingga meminimalkan getaran pada kendaraan. Sistem ini ditambahkan dengan aktuator untuk membantu peredaman getaran kendaraan terhadap permukaan jalan sehingga kenyamanan dalam berkendara semakin meningkat. Pada penelitian ini dilakukan pengujian performa dari sistem suspensi semi aktif pada kendaraan Yamaha Jupiter MX 135cc. Penelitian ini diawali dengan mencari parameter dan instrumen yang akan digunakan serta pemilihan metode dalam pengujian. Permodelan sistem suspensi terhadap Input disturbance berupa variasi tanggul jalan. Terdapat tiga jenis lintasan gangguan jalan berupa tanggul yaitu speed bump, speed hump dan speed table Pengujian ini dilakukan dengan variasi kecepatan 15, 30, dan 45 km/jam. Respon percepatan dan perpindahan sprung mass pada sistem suspensi yang dihasilkan kemudian di analisis sesuai dengan standar ISO 2631 dan dilakukan perbandingan performa antara suspensi pasif dengan suspensi semi-aktif. Dari hasil pengujian yang dilakukan, dengan nilai percepatan bodi suspensi pasif berturut-turut pada variasi tanggul speed bump 0,352 m/s², 0,387 m/s² dan 0,410 m/s². Pada variasi speed hump 0,499 m/s², 0,513 m/s² dan 0,537 m/s². Pada variasi speed table 0,427 m/s², 0,438 m/s² dan 0,472 m/s². Sedangkan pada hasil pengujian sistem suspensi semi-aktif dengan nilai percepatan bodi kendaraan berturut-turut pada variasi tanggul speed bump 0,336 m/s², 0,374 m/s² dan 0,396 m/s². Pada variasi speed hump 0,433 m/s², 0,465 m/s² dan 0,502 m/s². Pada variasi speed table 0,415 m/s², 0,432 m/s² dan 0,464 m/s². Semua hasil pengujian tersebut termasuk dalam kategori “Nyaman” menurut standar ISO 2631.

Motorcycles that are developing in society still have specifications that are still standard, such as suspensions that still use a passive system. This passive suspension system cannot adapt to changes in road surface because it still has a constant spring and damping constant. And it affects comfort when driving because the suspension system is less able to isolate vibrations on the vehicle body. Therefore, semi-active suspension system technology was developed. The semi-active suspension system is a suspension system that can adapt to changes in the road surface thereby minimizing vibrations on the vehicle. This system is added with an actuator to help reduce vehicle vibrations against the road surface so that driving comfort increases. In this study, performance testing of the semi-active suspension system on the Yamaha Jupiter MX 135cc vehicle was carried out. This research begins with finding the parameters and instruments to be used as well as choosing methods in testing. This study begins with modeling the suspension system for input disturbance in the form of variations in the road surface. This testing was carried out with variations of 15, 30 and 45 km/hour. Responses to the acceleration and displacement of the sprung mass in the resulting suspension system are then analyzed according to ISO 2631 standards and performance comparisons were made between passive suspension and semi-active suspension. From the results of the tests carried out, with the value of passive suspension body acceleration successively on the speed bump embankment variation 0.352 m/s², 0.387 m/s² and 0.410 m/s². At the speed hump variation 0.499 m/s², 0.513 m/s² and 0.537 m/s². At the speed table variation 0.427 m/s², 0.438 m/s² and 0.472 m/s². While in the test results of the semi-active suspension system with the acceleration value of the vehicle body successively on the speed bump embankment variation 0.336 m/s², 0.374 m/s² and 0.396 m/s². In the speed hump variation 0.433 m/s², 0.465 m/s² and 0.502 m/s². At the speed table variation 0.415 m/s², 0.432 m/s² and 0.464 m/s². All of these test results fall into the "Slightly Uncomfortable" category according to the ISO 2631 standard.
