摘要
在考虑空气阻力的影响下,对汽车以恒定输出功率加速行驶的过程进行了分析,得到了汽车运动的微分方程,且得到其终极速度随着功率的增大而增大,阻力系数的减小而减小的结论,进而对该理论进行了数值模拟和进一步讨论,得到功率越大,质量越小的汽车,百公里加速时间越短,与空气阻力系数无关的结论.
In this paper,the process of accelerating driving with constant output power is analyzed under the influence of air resistance. The differential equation of automobile motion is obtained and the ultimate velocity ncreases with the increase of power. The resistance coefficientAnd then the numerical simulation and further discussion on the theory,the greater the power,the smaller the quality of the car, 100 km faster acceleration time, and friction coefficient has nothing to do with the conclusion.
