Abstract
Sistem suspensi mempunyai peranan penting pada kendaraan sebagai penunjang kenyamanan dan keselamatan berkendara. Berbagai usaha telah dilakukan untuk meningkatkan performa sistem suspensi, salah satunya dengan menggunakan sistem suspensi aktif. Kebutuhan terhadap energi yang sangat besar pada sistem suspensi aktif menginspirasi banyak peneliti untuk meningkatkan performa sistem suspensi dengan kebutuhan energi yang tidak terlalu besar. Selain pemilihan pegas dan peredam yang sesuai, geometri sistem suspensi juga mempunyai pengaruh yang signifikan terhadap kinematika dan dinamika sistem suspensi. Sehingga salah satu usaha untuk meningkatkan performa sistem suspensi adalah dengan memanipulasi geometri sistem suspensi atau yang dikenal sebagai variable geometry suspension.
Pada penelitian ini akan dianalisis pengaruh perubahan geometri terhadap dinamika getaran sistem suspensi roda belakang sepeda motor. Perubahan geometri yang dianalisis adalah perubahan posisi bottom mounting suspensi dan panjang link untuk konstanta kekakuan pegas yang juga divariasikan. Dengan menggunakan numerical software, simulasi dilakukan secara dinamis terhadap sepeda motor Honda CBR 150R.
Dari hasil simulasi yang dilakukan diperoleh bahwa perbandingan respon getaran pada berbagai posisi bottom mounting suspensi memperlihatkan adanya pengaruh terhadap kekakuan pegas ekuivalen. Perbandingan respon getaran pada berbagai panjang link juga berpengaruh terhadap kekakuan pegas ekuivalen. Keduanya sebanding dengan perubahan konstanta kekakuan pegas yang digunakan. Selain itu, berdasarkan hasil simulasi, dibandingkan dengan suspensi Pro-Link, sistem suspensi yang dipelajari pada penelitian ini memberikan respon percepatan yang lebih baik. =========== Suspension system has notable role on vehicle as comfort and safety driving support. Considerable effort has been made to improve suspension system performance, one of them is using active suspension system. Requirement for the enormous energy on active suspension system has inspire lots of engineer to improve active suspension system performance with lower energy requirement. Apart from convenient spring and damper, suspension system geometry has significant impact to suspension system kynematics and dynamics. Then, one of the best effort to improve suspension system performance is to manipulate suspension system geometry as known as variable geometry suspension.
This study conducted analysis of effect of changes in suspension geometry to vibrational dynamics of motorcycle’s rear suspension system. Changes in the geometry being analyzed is suspension’s bottom mounting and linkage length for spring constant are varied as well. By using numerical sortware, model has dynamically simulated on Honda CBR 150R.
Based on simulation result, obtained that comparison of vibration response with various suspension’s bottom mounting position shows the effect on equivalent spring constant. Comparison of vibration respons eon various linkage length also affect to the equivalent spring constant. Both are proportional to the change in spring constant’s being used. Furthermore, based on simulation result, comparing to conventional suspension system, Pro-Link, suspension system being analized on this study provide better acceleration response.
