| 摘 要： | 为给多冰雪地区的城市道路线性设计提供参考,建立冰雪条件下车辆最大爬坡能力模型,从而计算冰雪条件下城市道路纵坡最大坡度建议值.根据车辆行驶理论,考虑车辆牵引力受冰雪路面摩擦条件的限制,建立冰雪条件下坡度计算模型,计算质量/功率比不同代表车型在不同冰雪路面的最大爬坡度,确定冰雪条件下城市道路设计速度在10～60 km/h的...

| Abstract: | To provide the reference for linearity design of the urban road of the multi-ice and snow area,the maximum climbing ability model of vehicle was established under ice and snowfall conditions,thus most steep bank recommendation value of lengthwise grade may be computed.According to traffic theory and the fact that the vehicle traction is restricted by the road friction conditions of ice and snow surface,the maximum climbing ability model of vehicle under snow and ice conditions was established,and it was use... |
