现代轿车的经常时速巳达100km左右,最高时速更达200km以上,因此轿车的车身设计既要服从空气动力学,要有尽量低的空阻系数,又要采取一定措施,在车身的前后端安装导流板和扰流板,以保证轿车的行驶安全。 在空气动力学中,有法国物理学家贝尔努依证明的一条理论:空气流的速度与压力成反比。也就是说,空气流速越快,压力越小;空气流速越慢,压力越大。例如飞机的机
Modern cars have a constant speed of 100 km has been reached, the maximum speed of more than 200km, so the car’s body design is subject to aerodynamics, to have a low air resistance coefficient, but also take some measures to install the front and rear body Baffles and spoilers to ensure the safety of cars. In aerodynamics, there is a theory demonstrated by the French physicist Bernhard Yiu: the speed of air flow is inversely proportional to the pressure. In other words, the faster the air flow rate, the smaller the pressure; the slower the air flow rate, the greater the pressure. For example, aircraft machine
