Abstract

Dalam penelitian ini diusulkan model suspensi baru menggunakan gabungan suspensi double wishbone dan candle type dengan variasi panjang lengan untuk meningkatkan performa kinematika kendaraan listrik 4WID-4WIS.
Desain model suspensi menggunakan perangkat lunak SolidWorks, dan analisis kinematika melalui simulasi berbasis multibody dynamics menggunakan MSC ADAMS. Simulasi dilakukan dalam dua kondisi utama, yaitu parallel wheel travel untuk mengevaluasi respons suspensi terhadap gerakan vertikal roda, serta kondisi manuver belok dengan memvariasikan sudut kemudi roda. Lima konfigurasi geometri suspensi diuji, yaitu SA, SLA1, SLA2, SLA3, dan LA. Parameter utama kinematic dianalisis berupa sudut camber, toe, caster, kingpin inclination (KPI), dan pergerakan roll center.
Hasil simulasi menunjukkan bahwa konfigurasi SLA3 memiliki performa kinematika paling stabil selama gerakan vertikal maupun saat perubahan sudut belok roda. Desain ini memiliki fluktuasi sudut camber dan toe yang rendah serta kestabilan sudut caster dan KPI yang tetap kecil. Penelitian ini diharapkan dapat menjadi acuan dalam pengembangan sistem suspensi untuk platform mobilitas masa depan yang mengedepankan steer-by-wire dan modularitas.

This study proposes a new suspension model that combines a double wishbone and candle-type suspension with variations in arm length to enhance the kinematic performance of a 4WID–4WIS electric vehicle.
The suspension model was designed using SolidWorks software, and the kinematic analysis was conducted through multibody dynamics simulations using MSC ADAMS. Simulations were carried out under two main conditions: parallel wheel travel to evaluate the suspension’s response to vertical wheel movement, and steering maneuvers by varying the wheel steering angles. Five suspension geometry configurations were tested: SA, SLA1, SLA2, SLA3, and LA. The key kinematic parameters analyzed included camber angle, toe angle, caster angle, kingpin inclination (KPI), and roll center movement.
Simulation results indicate that the SLA3 configuration delivers the most stable kinematic performance during both vertical motion and steering angle changes. This design exhibited minimal fluctuations in camber and toe angles, along with consistent caster and KPI stability. The findings of this study are expected to serve as a reference for the development of future mobility suspension systems that prioritize steer-by-wire functionality and modular design.
