摘要
利用伯努利原理,制作了演示马格努斯效应的风力小车,并对小车动力作了理论推导,进一步通过实测小车受力等数据,得到了小车受力的经验性公式,还对小车作了改进,使其结构更加轻巧,且增加了新的演示功能.
Using the Bernoulli principle,a wind-powered car that demonstrates the Magnus effect is produced,and the formula of the car's dynamics is theoretically derived.Further,through the actual measurement of the force of the car,the empirical formula of the force of the car is obtained.The car has also been improved to make it lighter and new demo features have been added.
