After completing the simulation development, let's do some analysis with this simulation model.
So we can change the discussion, mass density, our frontal area, but if we look at the values, the
direction is depend upon the design and alter shape of the body.
So drek option, well designed to discard Godric option can reach less 10 billion, zero point three
years.
We are having the same values depend upon the shape.
So if we consider the 3D image of sphere or how sphere are gone, then the deck will change like this.
Padukone and zero point five.
And if we can maintain the streamlined body, then we can reduce the recognition that today's modern
electrical can concentrate on reducing the decoction because that is the option to increase the maximum
speed and to improve the efficiency of the vehicle.
The decoction below zero point three, you can find in some very well-designed model of what we can
say, only a fire as a drug of zero point two five eight three model, the zero point two three.
And in that model three, that is the latest version of Tesla, achieved recognition of zero point twenty
one to one one electric vehicle from the General Motors, every one étude, the deck of value, less
than zero point to zero point one nine.
So this is what happening in the streets.
The designers are concentrating on reducing the decoction.
But as a system simulation, we need to really take protection that can be calculated by the design
engineer also.
And with the computer software simulation also by lifting the different kind of shapes so we can easily
take the different kind of shape and calculate the that when you get the frontal area, if the deck
of scientists left it data, Frontalot is also less, it will depend upon the shape of the vehicle.
The mass density of air, so in India, at the normal temperature, 20, 25 degrees, the mass density
of air will be won by tokaji parameter Kupe.
It is the volume of data at Parmeter, Kupe, it depend upon the temperature pressure.
We know that if temperature rise, the density of air will be reduced.
So at the lower temperature at zero degrees, this value will increase up to zero point to seven to
eight.
So as temperature reduce, the mass density of air will increase.
But this is the one corporation will.
But our goal is now to simulate and analyze the different options and match density with the same input,
to analyze and to observe the effect on the maximum speed that can be attained by the vehicle.
If you complicate your last exercise, please don't skip the exercise, do whatever the exercise that
you want, because it will inculcate the practice and skill in you.
So if you complicate the task and speed characteristic response, then detachable will be like this.
And if you plot does speed or characteristic, it will be look like this.
So we will store this data table and characteristic.
We will use this letter.
It will give the very good analytical result and will do how to analyze with only the speed.
Correct, because it represents a complete model of vehicle.
Now, let's simulate with the same values.
And we are having 127 kilometer per hour is the max speed for hundred Newton Mutata.
Now, what you need to do, you need to change the deck coefficient according to different value.
You can change also much that will be later, but for the same mass and same dynamics, if we can design
instead of zero point four and will be zanca zero point three decoction, then let's observe.
So from 127 to 146 so we can add to the higher maximum speed with the same input power.
But that means yet improving the efficiency of vehicle for the same amount of battery parts or for the
same amount of petrol or the same amount of input energy we had during the highest speed and higher
output.
Let's say with the same DNA, the mass density of air is high, it is temperature is low and if is one
point to seven.
Simulate, you can see the effect on maximum speed.
The test lab model.
Claimed Dragonfish zero point twenty one.
So you can see the speed can go up to the 170 from 127 to 170.
So how the design impact on the overall operations of the vehicle and for the high speed car, it is
very important to reduce the track of him.
So by doing this action meant practically you can realize and you will never forget the effect of take
action on the maximum speed and the descent because input is saying power is same, but we can achieve
the maximum speed.
At low speed, it will not affect too much, but for the high speed car, it is very important.
And frankly, they will also change with the brake.
It will produce a further improvement in speed, will be there.
Now, here we are not to the science yet, but we can use the Sanscrit if we want.
We can use the Onegin, which is multiplied by minus one and DeSanto plus one.
So what will happen during the positive spirit?
Positive Badakshan.
This will be the main minus and when it is Chinta plus it will become less so we can do this.
But what is wrong with the.
The US operation, because all the calculation of coalition and frontal area are depend upon the forward
direction, only the general in the simulation, we are only concentrating on the forward motion of
the vehicle because speed in the reverse motion is also not so high.
This this component also does not matter.
And if we want to simulate some vehicle with the high speed reverse operation, because when it is moving
in the direction, that, of course will be opposite to the direction of the vehicle.
But this discussion and frontal area will not remain the same because shape will be change from the
opposite side.
We need to understand.
So let us again make it to our initial will, zero point four and one point two.
You can do that.
So many experiment as you want.
You can also change the mass.
So do the same experiment in the vehicle radius will radius and observe the same things.
They're not in done now.
We will change the angle, beat the incline, the horizontal.
So this is a sign that this is in relation to understand for the simplicity.
We can change it to radion to angle.
So currently it is taking the input Israelian if I use the gain.
If with this gain, I consider I my 180 is the gain, so for the 180 input output at the gain will be
buy, so now it will remain high.
Plus, here we are having the.
So it is visible now.
So let's simulate for the parameters, 127 kilometer per hour is the maximum speed for the 100 meter
talk, let's increase the angle.
Two degree and observe what will be the final speed for increasing anger so you can see from the one
123 to one one four.
If increased up to five degrees or during incline, we require the higher force to attain the same speed.
Ninety one.
So at five degrees, let's say for the three degrees, you win at the three degree, one zero seven
point three.
Now, your exercise is you need to find how much talk is required to attain the 127 speed for the.
So our speed will be dimming seven one twenty seven.
And what is our angle?
Depending upon the speed that will vary.
So what torque is required for a particular angle, the target Newton meter and your angle in degree?
So I am writing Andre Knewton with the dog is required.
To attain 127 kilometer per hour speed.
What a zero angle.
Now, if I change angle to.
Two degree.
One one four is the speed, so I need to increase this, so what I will do, I will do one zero.
Oh, and check it out, you can see it's still not enough to have the running analysis, we use the
slider gain.
Here is the slide again and.
We will adjust to input from the slider gain, so if, say, the maximum value is 200.
And now this will become one constant one, and yet we are changing the.
Doc.
Let's say it is 100.
Again, I will simulate.
But yet we can do the simulation with the.
Infinite times, it will run continuously.
You can see the final sprint is a thing and now we can increase the speed.
You can see increased the dark will result in increased the speed, what, really quite 127 kilometers
per hour.
So when we reach.
So it is.
One one nine one one nine is fine, but we can see one one nine point five point two point one one one
nine point one is to we can stop the simulation.
One one nine point one with the two degree, so from the one degree to five degree zero one, two,
three, four, five, you need to repair this lookup table.
It will give idea what maximum power we require because this is the maximum Takuji required in the 120
circular without considering the incline.
But when we consider it, the required for the same speed is higher.
So do this practice.
Later, we will use it.
I hope you understand the basic concept of simulating any vehicle with the help of metallic simulation
software.
