由于某些地区自然环境的特殊性,风压比较大,为了保证行车安全,必须进行不同方向的风压对汽车行驶的横向稳定性分析,得出不同方向的风压影响下圆曲线最小半径公式并与文献[2]采用的最小半径公式进行比较,提出的风压向外侧时的圆曲线最小半径公式是合理的。同时运用此结论计算出不同海拔、不同等级风影响下的圆曲线一般最小半径,可供公路设计时参考。
Due to the particularity of the natural environment in some areas and the relatively large wind pressure, in order to ensure the traffic safety, the transverse stability analysis of wind pressure in different directions to vehicle driving must be carried out, and the formula of the minimum radius of circular curve under different wind pressures is obtained And compared with the minimum radius formula used in [2], the formula of the minimum radius of the circular curve when the wind pressure is to the outside is reasonable. At the same time, this conclusion is used to calculate the minimum radius of the circular curve under the influence of different altitudes and different levels of wind, which can be used as reference for highway design.
