Design and Simulation of multi-link front suspension for ATV

In this paper the multi-link suspension for an All-Terrain Vehicle is designed, modeled and simulated. The model was produced by defining the position of the hardpoint or coordinate before specifying the component characters and joint variety, then after for modelling of the multi-link suspension, CATIA 3D modelling approach is used, sequentially the MBD approach is adopted for full suspension model simulation. The same test was conducted for the base model (double wishbone suspension) which was holding the same characteristics. The kinematics and compliance of the simulation are matched with the base model simulation data to verify the suspension design and the result from the simulation exposed a validated virtual suspension system model with a pretty minimal rate of error. The result of the simulation shows that the introduced suspension system decreases the camber angle generation and bump steer along with this it gives the quick cornering and straight-line stability.
