System level simulation of all-terrain vehicle.

BAJA ATV with DASHBOARD MODEL

This is a dashboard simulation model for ATV. in this input is given through brake and throttle knobes.

Different values are given and velocity,RPM and CVT shaft speed are being observed along with other values.

Intial conditions to run the simulation are

Brake=0 and throttle=0.5

In this model Generic engines are employed because only basic parameters are used.

the input to the CVT is generated by signal builder.

The layout of CVT is given below

Ideal rotational motion sensors are used here

The simulink model for for vehicle body is as shown below

Velocity and distance is being determined from vehicle body.

This is fed to the scope later on.

Two wheel per axle configuration is adopted.

Conditions:

1.Brake = 0 and throttle =0.5

CVT rpm obtained is shown above.it shows that after 25 seconds the RPM becomes constant and recah satuartion

2.Brake =0.4 and throttle=0.5

As the brake value is increased the decrease in RPM can be observed. the RPM value has been brought after 3 seconds.

After intial increase in velocity, drop in velocity with increase in distance is observed.

3.Brake=0.4 and throttle =0.9

with the constant increase in distance the velocity increases .

velocity recahes saturation after 25 seconds.

Conclusion:

Thus system level analysis of ATV simulation has been successfully completed. the analysis is done for different values of brake and throttle. various parameters are being checked.

With increase in the RPM/Gear turn ratio Torque increases upto a limit and when reaches a certain RPM then it reduces and velocity increases.
