I believe many people have this question. In the end, what is the speed at which the car is overturned? When we talk about this issue, we first exclude the difference in the size of the car, as well as the driver's driving skills and the configuration of the vehicle. Before talking about this, Xiao Bian still reminded the majority of owners that the speed must be reduced before the turn. As long as your speed is within a reasonable range, the probability of wanting to roll over is a finger-level. In China's road design, the turning radius of the urban arterial road is generally 20-30 meters. When the turning radius is determined, we talk about the centrifugal force. The centrifugal force is replaced by the letter F. M stands for quality, V stands for speed, and r stands for turning. radius. We can get the formula: F=MV2/r, so that it is relatively easy to understand. The smaller the running speed of the same quality model is, the smaller the MV2 is, the smaller the F, the smaller the centrifugal force, and the possibility of overturning. The smaller it is. This is about centrifugal force, so let's look at a case. Take Xiaobian Cruze (2013 MTSE) as an example, the vehicle height is roughly calculated to be 1.5 meters and the width is 1.8. The vehicle weight plus the person's count is 1.5t, the center of gravity is about 0.5 meters to the ground, and about 0.8 meters to the edge of the tire is the force. arm. According to the moment formula F·L1>Mg·L2, F is the centrifugal force, L1 represents the center of gravity, L2 represents the arm, and Mg represents the gravity of the car. 0.5F> 15000X0.8, so F> 24000 cattle Cruze will roll over, then F centrifugal force formula we mentioned earlier is: F = MV2/r, this time we will be in the speed of 60km / h Under the rollover, you can calculate the turning radius: F=24000, M=1500, V=60km/h is equal to about 16.66m/s, then r is 1500X16.662÷24000≈17 meters, which means that the speed of 60 steps is open. If you do, make sure that the radius of the roll does not exceed 17 meters. If you encounter a highway ramp, the speed must be reduced to 40 yards or less before entering the ramp, because the ramp radius of the ramp is too small, and even some places are not even 8 meters. There is no other way to enter the ramp and then slow down, the reason is very simple, because the moment of turning the car center of gravity will shift, if the brakes will cause more severe roll, or even unilateral braking, so be sure to enter before the ramp slow down! 1.
