Week 7 Challenge
Load the vehicle parameters. Complete the vehicle model by modelling the remaining equations. Set simulation stop time to 598 sec.
The output should be the vehicle velocity.
Aim:
To load vechicle parameters and to complete the vechicle model by modelling the remaining equations,to set simulation stop time to 598 sec.
In this simulink model need to develop a model vechicle which is used to find out all the tractive force acting on the vechicle and the power required to overcome this all the resistive force acting on it and propel the vechicle as per the reference speed given/
Most of the 3 major resistive forces acting on it and know the actual mean
Rolling Resistance:
Aerodynamic Drag:
The aerodynamic drag is directly proportional speed of the vechicle.Along the speed of the vechicle the aerodynamic drag also depends on the frontal area or the frontal shape of the vechicle.The vechicle when moving forward,leaves behind on the area of loe pressure.
Grading Resistance:
When the car is going up hill it experience an additional resistance componant which is due to the grade of the road and is called the grade resistance but when going downhill,it helps in the motion of the vechicle.The amount of grade resistance or assistance depends on the mass of the vechicle demands as M and is given as:
Force= Mass*aceeleration.
Acceleration=Force/mass
