Project

Aim:

To Prepare a technical report explaining the model properties & comments on the results of a continuously variable transmission (CVT) model of All Terrian vehicle.

Result:

All Terrian vehicle:

Terrian vehicles are the vehicles designed to drive in the off-road conditions, for which the maximum all the vehicles are designed as All wheel drive(AWD), handle bar for steering control and also it is designed in the way that it operates on roboust conditions.

Explanitation of Model:

The image of the model is being attached in the attachment

The components used in the model are as follows

(i) Continuously variable transmission (CVT)

(ii) Engine

(iii) Input signals

(iv) Vehicle body

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.

CVTs are used in automobiles,Tractors, Scooters,bicycles, and earth movers.

The most common type of CVT uses two pullys connected by a belt or chain; however, several other designs have also been used at times.

The Engine block represents a CI or SI engine according the operation. The signals to the models are throttle controller which demands the torque to meet the load provided on certain conditions. The connections B and F are the engine block and the rotational force connected to the engine. FC measures the fuel consumption of the engine block.

The Input signals are the signals that are provided to the engine block and to the CVT.

To the engine Brake input and the throttle are the two input signals that are provided and for the CVT the gear ratio input is provided.

output Case 1:

In case 1 the value provided as the predifined value of torque and cvt the provided values are ploted as the output the out put graphs are plotted as attachment

output case 2

in second case the the inputs(throttle and spped) to the engine is being varied, the model is attached to the results and the respective outputs also attached
