Project

To carry out system –level simulation of an all-terrain vehical using Simulink.
1) Bajaj Atv model without dashboard
These model consist of,
Signal builder block which is use for create interchangeable groups of piecewise linear signal and use them in model.
Genric engine represent a system level model of spark ignition and disel engines. For use at initial stage of modeling when only the basic parameters are available
Engine sensor: Ideal rotational motion sensor – That block is convert an across variable measured between two mechanical rotational node into a control signal proportional to angular velocity and angle.
Simple gear : Represent a fixed ratio gear or gearbox. No inertia or compliance is modeled in this bock.
CVT Subsystem :It consist of inertia,variable ratio transformation,
Vehical body subsystem: It consist of vehical body, Tire, Double shoe break .

.

Shaft speed

With dashboard: A dashboard is control panel usually located directly ahead of a vehicals driver,displaying instrumentation and controls for the vehicals operation

2 BAJA CVT using lookup table
Without dashboared

Lookup table : A look table is an array of data that maps input values to output values , thereby approximating a mathematical function.

With dashboared.

Conclusion : Velocity,CVT shaft speed and engine speed are directly proportional to the throttle input and inversely proportional to the break input.
CVT ratio is directly proportional to torque and inversely proportional to the throttle input.
CVT primary speed is greater than CVT secondary speed as they are directly proportional to their shaft diameter.
The speed might get null at a particular braking resistance.
