Abstract

Suspensi merupakan komponen penting pada kendaraan bermotor karena berperan penting dalam menjaga kenyamanan dan keamanan saat berkendara. Sebuah ide baru diperkenalkan yaitu, Series Active Variable Geometry Suspension (SAVGS), dimana sistem suspensi ini memiliki performa yang lebih baik dari suspensi pasif dan dapat mengatasi kelemahan dari suspensi aktif. Penelitian terus dilakukan guna meningkatkan performa dari SAVGS. Pada penelitian ini akan dipelajari pengaruh panjang linkage (single link) terhadap performa kendaraan khususnya kenyamanan dan stabilitas. Model seperempat kendaraan digunakan untuk memodelkan dinamika sistem suspensi kendaraan. Pengaruh panjang single link dianalisis dalam bentuk koefisien kekakuan dan koefisien peredam. Model linier digunakan untuk merancang state-feedback control system (LQR). Kinerja sistem kendali diuji pada model nonlinier yang dibuat dengan menggunakan Simscape Multibody. Hasil simulasi menunjukkan bahwa semakin panjang single link yang digunakan maka kenyamanan dan stabilitas kendaraan semakin besar. Namun, semakin panjang single link diperlukan input kontrol yang lebih besar.

Suspension is an important component in vehicles because it plays an important role in maintaining comfort and safety while driving. A new idea was introduced, namely, Series Active Variable Geometry Suspension (SAVGS), where this suspension system has better performance than passive suspension and can overcome the weaknesses of active suspension. Research continues to improve the performance of SAVGS. The effect of linkage length (single link) on SAVGS performance, especially comfort and stability, is studied. A quarter car is used to model the dynamics of the vehicle suspension system. The effect of single link length is analyzed in the form of stiffness coefficient and damping coefficient. The linear model is used to design the state-feedback control system (LQR). The performance of the control system was tested on a nonlinear model made using Simscape Multibody. The simulation results show that the longer the single link used, the greater the vehicle's comfort and stability. However, the longer the single link required more considerable control input.
