2)空气阻力空气阻力大部分来自车辆行驶时风在车辆迎风面积上施加的冲击阻力,还有一少部分空气阻力是气流流经车身,与车身表面摩擦产生的阻力。空气阻力与车辆风阻系数、车辆正面投影面积和车速有着密切的关系。
2) Air resistance Most of the air resistance comes from the impact resistance of the wind on the windward area of the vehicle while the vehicle is running. There is also a small part of the air resistance which is the resistance caused by the airflow flowing through the vehicle body and the friction with the vehicle body surface. Air resistance and vehicle drag coefficient, the front of the vehicle projection area and speed are closely related.
