How to jump the fastest when godeam starts?
The ultimate puzzle that haunts all go-karts is solved. Entertainment karting competition start everyone must have seen this kind of picture, there are jumps and shakes, there are light weight is not afraid, so is it useful to start like this? Today, professional instruments and scientific analysis are used together to solve the puzzles of the century.
Getting Started Assessment Video
Mei Meibiao did such a test a few days ago to raise this question, he concluded that the jumping effect is the same, and my idea is very different, I have also discussed in the past, I think it is the transfer of the department mass extension torque curve. I have always believed that jumping is useful, the result of thinking from the theoretical level, and I have always thought that it is right, and I will explain the physical principles of this in detail later in the program. But this is also a question that has made me curious for a long time, and I have always wanted to prove that this time we use professional analysis instruments to reveal the truth, and this time we can also know what posture works best and how to correctly pile up. The meter can eliminate the error of artificial pinching, and the 50 hz GPS data can see that even a gap of 0.01 seconds can eliminate the error between the starting point and the end point.
This test uses four kinds of postures, no, it is posture, no should be called action, the first is to directly step on the accelerator to start, the second is to bounce up and down directly in situ, like Mario Racing, the third is to jump forward, which is also the action that some professional kart drivers will occasionally do when going uphill at low speeds, and the fourth is to swing back and forth, which I have always found useless
Okay, straight to the conclusion
After three tests of each of our movements, the way to directly step on the throttle starts at 60 meters and the fastest time is 6.96 seconds, the vertical bounce starts at 6.88, the frog jump is the fastest 6.73, the rocknroll is the fastest 6.90. The fastest 6.90 and the slowest 7.02 is slower than the direct start; the direct start and up and down bounce fluctuations are very small, and the frog jump fluctuations are also large, but his slowest 6.85 seconds is still the fastest of the four ways. Therefore, it seems that if you want to shake your head back and forth to be fast, you must shake the rhythm and have a high synchronization rate with the car. Very unstable.
So the conclusion is frog jumping, boy. But the frog jump also has its own shortcomings, unskilled case will cause the throttle to be slightly loose, but it will be slow.
When we compare the data, we can clearly see the effect of our speed curve when driving piles. This effect can only be seen on precise gauges. You can see the huge starting fluctuations in the speed of the rocking back and forth, jumping up and down on the line of direct starting, and the fluctuations are very large. Let's look at the frog jump, the curve is also volatile, but it is all fluctuating on the standard line. Each forward jump gives the car a good light load release. This is also why when you meet light friends, you always accelerate behind them.
Of course, I also used the two-punch professional car to test, the conclusion is still in line with the four-punch car, the way to jump up will be a little faster is 6.12 seconds, the regular OK level competition is dynamic start is not used to use this, and the two-punch static start There is an uncertainty factor of residual oil in the low-turn combustion cylinder, the consistency is not high enough, just as a reference.
Later, I used the flying circle stop and start again, and tested the next two strokes, and the results should be more rigorous. Straight start 5.47s, up and down 5.56s, frog jump 5.49s, Rock 5.45s. It may be better to say that the second punch or honest start may be better, because it is more motivated and it is better to do less small actions.
Talking about the principle, many people may think, jumping around the total mass has not changed... Because the acceleration curve of this single-speed kart is about this, acceleration has to go through the process of going from low to high rotation, and the torque of low rotation is much smaller than that of high rotation, and the torque decay will basically correspond to the speed of 40. We jump up and down again, so that the low rotation acceleration is smaller mass, although this mass will fall to hinder acceleration, but has passed through the last low rotation area, equivalent to throwing this mass to the high rotation area to accelerate again. On average, it will definitely be faster. The forward jump is the same as the car goes through a stretch of relaxation when we're moving forward and then catches us
As for whether there is a systematic error this time, I am ready to find Mei Meibiao to test it again, talk about the start of the entertainment karting competition, and look forward to it
