Project

Aim- To carry out system level simulation of the given atv model

and also to create a techical report with model properties and its details

Description: Basically we have been provided with 3 models of atv with cvt

our task is to carry out simulation and write the report regarding the model.

a)following is the simulink model for atv

some of the major blocks which have been adopted from the librabry itself are as follows.

1.engine

2.scope

3.signal builder

4.constant blocks

5.solver

6.custom gauge etc

b)we can see that the cvt with time (sec) in our signal builder block

c)we can also find the engine rpm by connecting the following to the scope

the result of this is nothing but the engine rpm wrt time

y axis denotes the engine rpm and x axis shows time

d)Cvt is nothing but constant variable transmission ,unlike other transmisson this has greater efficiency and smooth transmisson

following is the simulink model for cvt

e)following is the torque and speed curve

where speed is denoted in the x axis and torque is been shown on the y axis

*)Following are the plot or graph results of the parameters brake torque shaft speed etc

following is the scope of shaft speed both primary and secondary

Conclusion :From the use of all the display,scope ,signal builder blocks we can virtually get to know certain values of cvt model

and thus from changing the input values such as brake throttle we can see the change on other parameters such as shaft speed,etorque,etc
