Result for CVT model:-

When we increase the throttle input from 0to 20 and we observe the scope at the output the velocity get increases from 0 to 330 km/hr the distance is from 0 to 180m at the CVT shaft speed by applying the primary and secondary input we observe the CVT primary speed is from 0 to 3400 rpm and the CVT secondary speed is from 0 to 2700 rpm we also observe the engine torque speed curve as attached in the figure.

Block parameter vehicle body

Mass	250kg
Number of wheels per axle	2
Horizontal distance from CG to front axle	1 Minute
Horizontal distance from CG to Real axle	35 Minute
CG height above ground	0.7 m
Gravitational Acceleration	9.81 m/s^2

2) CVT DASHBOARD

ADDITIONAL BLOCKS USED FROM CVT MODEL ARE:-

1. Circular Gauge Blocks
2. KNOB blocks

Result for CVT Dashboard:-

Circular Gauge used as speed meter has a minimum 0 and a maximum 10,000 rpm at the tick interval of 2500. the circular gauge used as velocity measurement has a minimum 0 and a maximum 100 m/s with a tick interval of 20 m/s. Here as the brake input we used a knob block with the minimum 0 and maximum 0.5 with the tick interval of 0.10000000000000001, we have another knob that is connected to the throttle input value with a minimum 0.29999999999999999 and maximum 01 with a tick interval of 0.100000000000000001.

3) CVT RATIO

By changing the throttle value we can change the velocity and the CVT ratio is also been changed.

CONCLUSION OF THE PROJECT:-

The project was to study the model of the Baja all-terrain vehicle (ATV) which is build with the help of the mentioned components or blocks and to analyse the various output we obtain from the the project with the help of the throttle we use to change the speed(rpm) and the shift of the gear we also observe from the given project.
