Abstract
The final drivetrain ratio is an essential part of a vehicle. It is responsible
for providing the desired torque to overcome obstacles while maintaining the
speed and acceleration of a vehicle. A vehicle must have an optimum gear ratio
to obtain the desired velocity and acceleration. To achieve this, four different
approaches were used considering the input parameters of a BAJA All-Terrain
Vehicle (ATV). The traction received from the ground is calculated and plotted
against velocity on different terrains. Further, a drivetrain was modeled in
Simulink to obtain different parameters like vehicle speed, acceleration, and
wheel slip. A range of gear ratios was obtained by following a similar trend of
vehicle parameters that were best suited for improving vehicle performance.
Graphs were plotted to compare the effect of various vehicle parameters, and an
optimum gear ratio was obtained. Based on the obtained results, it can be
concluded that a gear ratio ranging from 7.5 to 8.5 will provide the optimum
ratio and exhibit a consistent trend of results.
