1 00:00:02,780 --> 00:00:09,370 After completing the simulation development, let's do some analysis with this simulation model. 2 00:00:11,490 --> 00:00:19,470 So we can change the discussion, mass density, our frontal area, but if we look at the values, the 3 00:00:19,480 --> 00:00:25,740 direction is depend upon the design and alter shape of the body. 4 00:00:26,640 --> 00:00:33,840 So drek option, well designed to discard Godric option can reach less 10 billion, zero point three 5 00:00:35,220 --> 00:00:35,630 years. 6 00:00:36,210 --> 00:00:39,750 We are having the same values depend upon the shape. 7 00:00:40,290 --> 00:00:50,310 So if we consider the 3D image of sphere or how sphere are gone, then the deck will change like this. 8 00:00:50,310 --> 00:00:52,510 Padukone and zero point five. 9 00:00:53,190 --> 00:01:01,320 And if we can maintain the streamlined body, then we can reduce the recognition that today's modern 10 00:01:01,320 --> 00:01:08,100 electrical can concentrate on reducing the decoction because that is the option to increase the maximum 11 00:01:08,100 --> 00:01:11,870 speed and to improve the efficiency of the vehicle. 12 00:01:14,110 --> 00:01:21,580 The decoction below zero point three, you can find in some very well-designed model of what we can 13 00:01:21,580 --> 00:01:29,860 say, only a fire as a drug of zero point two five eight three model, the zero point two three. 14 00:01:30,190 --> 00:01:39,010 And in that model three, that is the latest version of Tesla, achieved recognition of zero point twenty 15 00:01:39,160 --> 00:01:49,180 one to one one electric vehicle from the General Motors, every one étude, the deck of value, less 16 00:01:49,180 --> 00:01:52,360 than zero point to zero point one nine. 17 00:01:52,810 --> 00:01:54,810 So this is what happening in the streets. 18 00:01:55,060 --> 00:01:58,510 The designers are concentrating on reducing the decoction. 19 00:01:58,750 --> 00:02:05,320 But as a system simulation, we need to really take protection that can be calculated by the design 20 00:02:05,320 --> 00:02:06,190 engineer also. 21 00:02:06,370 --> 00:02:14,950 And with the computer software simulation also by lifting the different kind of shapes so we can easily 22 00:02:14,950 --> 00:02:22,180 take the different kind of shape and calculate the that when you get the frontal area, if the deck 23 00:02:22,180 --> 00:02:30,090 of scientists left it data, Frontalot is also less, it will depend upon the shape of the vehicle. 24 00:02:31,400 --> 00:02:39,500 The mass density of air, so in India, at the normal temperature, 20, 25 degrees, the mass density 25 00:02:39,500 --> 00:02:42,230 of air will be won by tokaji parameter Kupe. 26 00:02:42,530 --> 00:02:48,770 It is the volume of data at Parmeter, Kupe, it depend upon the temperature pressure. 27 00:02:48,800 --> 00:02:53,530 We know that if temperature rise, the density of air will be reduced. 28 00:02:54,080 --> 00:03:02,480 So at the lower temperature at zero degrees, this value will increase up to zero point to seven to 29 00:03:02,570 --> 00:03:03,050 eight. 30 00:03:04,190 --> 00:03:08,510 So as temperature reduce, the mass density of air will increase. 31 00:03:09,660 --> 00:03:11,610 But this is the one corporation will. 32 00:03:12,360 --> 00:03:22,830 But our goal is now to simulate and analyze the different options and match density with the same input, 33 00:03:23,310 --> 00:03:30,270 to analyze and to observe the effect on the maximum speed that can be attained by the vehicle. 34 00:03:31,540 --> 00:03:39,790 If you complicate your last exercise, please don't skip the exercise, do whatever the exercise that 35 00:03:40,060 --> 00:03:44,650 you want, because it will inculcate the practice and skill in you. 36 00:03:45,070 --> 00:03:53,040 So if you complicate the task and speed characteristic response, then detachable will be like this. 37 00:03:53,320 --> 00:03:59,310 And if you plot does speed or characteristic, it will be look like this. 38 00:03:59,680 --> 00:04:03,690 So we will store this data table and characteristic. 39 00:04:03,700 --> 00:04:04,850 We will use this letter. 40 00:04:05,140 --> 00:04:11,040 It will give the very good analytical result and will do how to analyze with only the speed. 41 00:04:11,110 --> 00:04:15,130 Correct, because it represents a complete model of vehicle. 42 00:04:16,270 --> 00:04:19,810 Now, let's simulate with the same values. 43 00:04:22,470 --> 00:04:29,790 And we are having 127 kilometer per hour is the max speed for hundred Newton Mutata. 44 00:04:30,840 --> 00:04:35,660 Now, what you need to do, you need to change the deck coefficient according to different value. 45 00:04:36,180 --> 00:04:43,440 You can change also much that will be later, but for the same mass and same dynamics, if we can design 46 00:04:43,470 --> 00:04:51,750 instead of zero point four and will be zanca zero point three decoction, then let's observe. 47 00:04:53,550 --> 00:05:01,790 So from 127 to 146 so we can add to the higher maximum speed with the same input power. 48 00:05:02,250 --> 00:05:07,800 But that means yet improving the efficiency of vehicle for the same amount of battery parts or for the 49 00:05:07,800 --> 00:05:15,210 same amount of petrol or the same amount of input energy we had during the highest speed and higher 50 00:05:15,360 --> 00:05:15,930 output. 51 00:05:19,670 --> 00:05:31,190 Let's say with the same DNA, the mass density of air is high, it is temperature is low and if is one 52 00:05:31,190 --> 00:05:32,270 point to seven. 53 00:05:35,550 --> 00:05:40,230 Simulate, you can see the effect on maximum speed. 54 00:05:43,670 --> 00:05:45,230 The test lab model. 55 00:05:49,450 --> 00:05:53,860 Claimed Dragonfish zero point twenty one. 56 00:05:55,120 --> 00:06:01,750 So you can see the speed can go up to the 170 from 127 to 170. 57 00:06:01,750 --> 00:06:08,710 So how the design impact on the overall operations of the vehicle and for the high speed car, it is 58 00:06:08,710 --> 00:06:11,010 very important to reduce the track of him. 59 00:06:11,020 --> 00:06:18,410 So by doing this action meant practically you can realize and you will never forget the effect of take 60 00:06:18,430 --> 00:06:25,810 action on the maximum speed and the descent because input is saying power is same, but we can achieve 61 00:06:25,810 --> 00:06:27,220 the maximum speed. 62 00:06:29,750 --> 00:06:36,330 At low speed, it will not affect too much, but for the high speed car, it is very important. 63 00:06:36,890 --> 00:06:39,350 And frankly, they will also change with the brake. 64 00:06:39,740 --> 00:06:43,150 It will produce a further improvement in speed, will be there. 65 00:06:44,330 --> 00:06:49,250 Now, here we are not to the science yet, but we can use the Sanscrit if we want. 66 00:06:49,250 --> 00:06:54,670 We can use the Onegin, which is multiplied by minus one and DeSanto plus one. 67 00:06:55,040 --> 00:06:58,220 So what will happen during the positive spirit? 68 00:06:58,220 --> 00:06:59,190 Positive Badakshan. 69 00:06:59,330 --> 00:07:07,740 This will be the main minus and when it is Chinta plus it will become less so we can do this. 70 00:07:07,760 --> 00:07:10,340 But what is wrong with the. 71 00:07:11,800 --> 00:07:19,480 The US operation, because all the calculation of coalition and frontal area are depend upon the forward 72 00:07:19,480 --> 00:07:26,440 direction, only the general in the simulation, we are only concentrating on the forward motion of 73 00:07:26,440 --> 00:07:30,130 the vehicle because speed in the reverse motion is also not so high. 74 00:07:30,400 --> 00:07:33,200 This this component also does not matter. 75 00:07:33,610 --> 00:07:41,650 And if we want to simulate some vehicle with the high speed reverse operation, because when it is moving 76 00:07:41,650 --> 00:07:46,940 in the direction, that, of course will be opposite to the direction of the vehicle. 77 00:07:47,410 --> 00:07:55,510 But this discussion and frontal area will not remain the same because shape will be change from the 78 00:07:55,510 --> 00:07:56,590 opposite side. 79 00:07:57,250 --> 00:07:58,990 We need to understand. 80 00:08:00,370 --> 00:08:07,450 So let us again make it to our initial will, zero point four and one point two. 81 00:08:07,480 --> 00:08:08,250 You can do that. 82 00:08:08,260 --> 00:08:10,580 So many experiment as you want. 83 00:08:12,190 --> 00:08:13,780 You can also change the mass. 84 00:08:14,530 --> 00:08:20,700 So do the same experiment in the vehicle radius will radius and observe the same things. 85 00:08:20,700 --> 00:08:22,840 They're not in done now. 86 00:08:22,840 --> 00:08:28,940 We will change the angle, beat the incline, the horizontal. 87 00:08:29,500 --> 00:08:36,040 So this is a sign that this is in relation to understand for the simplicity. 88 00:08:36,040 --> 00:08:39,810 We can change it to radion to angle. 89 00:08:40,180 --> 00:08:44,740 So currently it is taking the input Israelian if I use the gain. 90 00:08:48,290 --> 00:09:01,510 If with this gain, I consider I my 180 is the gain, so for the 180 input output at the gain will be 91 00:09:01,670 --> 00:09:05,710 buy, so now it will remain high. 92 00:09:05,940 --> 00:09:07,520 Plus, here we are having the. 93 00:09:20,880 --> 00:09:22,160 So it is visible now. 94 00:09:34,520 --> 00:09:42,780 So let's simulate for the parameters, 127 kilometer per hour is the maximum speed for the 100 meter 95 00:09:43,190 --> 00:09:46,610 talk, let's increase the angle. 96 00:09:48,050 --> 00:09:55,040 Two degree and observe what will be the final speed for increasing anger so you can see from the one 97 00:09:55,040 --> 00:09:57,770 123 to one one four. 98 00:09:59,720 --> 00:10:06,620 If increased up to five degrees or during incline, we require the higher force to attain the same speed. 99 00:10:07,940 --> 00:10:09,500 Ninety one. 100 00:10:10,070 --> 00:10:18,080 So at five degrees, let's say for the three degrees, you win at the three degree, one zero seven 101 00:10:18,080 --> 00:10:18,690 point three. 102 00:10:19,040 --> 00:10:28,250 Now, your exercise is you need to find how much talk is required to attain the 127 speed for the. 103 00:10:31,150 --> 00:10:34,930 So our speed will be dimming seven one twenty seven. 104 00:10:37,180 --> 00:10:39,750 And what is our angle? 105 00:10:41,460 --> 00:10:44,740 Depending upon the speed that will vary. 106 00:10:45,060 --> 00:10:57,900 So what torque is required for a particular angle, the target Newton meter and your angle in degree? 107 00:11:02,680 --> 00:11:07,540 So I am writing Andre Knewton with the dog is required. 108 00:11:08,570 --> 00:11:12,080 To attain 127 kilometer per hour speed. 109 00:11:16,750 --> 00:11:18,000 What a zero angle. 110 00:11:18,520 --> 00:11:21,430 Now, if I change angle to. 111 00:11:26,910 --> 00:11:27,540 Two degree. 112 00:11:30,490 --> 00:11:36,880 One one four is the speed, so I need to increase this, so what I will do, I will do one zero. 113 00:11:38,410 --> 00:11:48,100 Oh, and check it out, you can see it's still not enough to have the running analysis, we use the 114 00:11:48,100 --> 00:11:49,000 slider gain. 115 00:11:56,120 --> 00:11:58,910 Here is the slide again and. 116 00:12:02,200 --> 00:12:10,090 We will adjust to input from the slider gain, so if, say, the maximum value is 200. 117 00:12:11,650 --> 00:12:18,280 And now this will become one constant one, and yet we are changing the. 118 00:12:26,620 --> 00:12:27,160 Doc. 119 00:12:30,670 --> 00:12:32,410 Let's say it is 100. 120 00:12:35,930 --> 00:12:37,380 Again, I will simulate. 121 00:12:39,510 --> 00:12:42,270 But yet we can do the simulation with the. 122 00:12:45,620 --> 00:12:48,210 Infinite times, it will run continuously. 123 00:12:48,740 --> 00:12:54,640 You can see the final sprint is a thing and now we can increase the speed. 124 00:12:55,460 --> 00:13:02,090 You can see increased the dark will result in increased the speed, what, really quite 127 kilometers 125 00:13:02,090 --> 00:13:03,270 per hour. 126 00:13:04,310 --> 00:13:05,480 So when we reach. 127 00:13:06,080 --> 00:13:06,820 So it is. 128 00:13:08,030 --> 00:13:17,630 One one nine one one nine is fine, but we can see one one nine point five point two point one one one 129 00:13:17,630 --> 00:13:23,600 nine point one is to we can stop the simulation. 130 00:13:26,010 --> 00:13:36,780 One one nine point one with the two degree, so from the one degree to five degree zero one, two, 131 00:13:37,260 --> 00:13:41,250 three, four, five, you need to repair this lookup table. 132 00:13:41,550 --> 00:13:48,600 It will give idea what maximum power we require because this is the maximum Takuji required in the 120 133 00:13:48,600 --> 00:13:51,440 circular without considering the incline. 134 00:13:51,690 --> 00:13:55,890 But when we consider it, the required for the same speed is higher. 135 00:13:55,920 --> 00:13:57,690 So do this practice. 136 00:13:59,320 --> 00:14:00,820 Later, we will use it. 137 00:14:03,790 --> 00:14:10,600 I hope you understand the basic concept of simulating any vehicle with the help of metallic simulation 138 00:14:10,780 --> 00:14:11,350 software.
