Optimization of Suspension and Steering Systems of an Electric
All-Terrain Vehicle (e-ATV) for Improving Vehicle Performance 2023-01-5159
The Baja Electrical All-Terrain Vehicle eATV is a versatile off-road vehicle
designed to tackle challenging terrains and endure extreme conditions.
Suspension system in a car connects the chassis to its wheels and it comprises
of a system of springs, dampers and linkages. Independent suspension systems
typically offer better handling and ride quality. This paper focuses on the
optimization of the eATV’s suspension and steering systems to enhance its
performance, stability, and maneuverability. For explanation purpose the design
methodology that has been chosen for the suspension system of an all-terrain
vehicle. A double wishbone independent suspension is designed for the front
half, and an H-arm independent suspension is designed for the rear half. The
steering system uses a Rack & Pinion gearbox along with this Ackerman
geometry being used for the steering assembly. Theoretical values were validated
with the help of ‘Lotus Shark’ software. Also highlights the challenges faced by
this design and the solutions adopted to overcome them.
