| 摘 要： | 由于运输效率提升的需要,一辆汽车会拖挂多台挂车,为了满足后期运营场景,在设计之初就应对这种汽车列车的最小转弯半径进行计算,评估运营场地或道路情况。文章主要通过汽车列车转动时没有相对转动角速度这一前提条件,对拖拽多台挂车的汽车列车的最小转弯半径进行分析计算,从而得出拖拽3台挂车的最小转弯半径公式,并由此推导出拖拽n台挂车的转弯半径的计算公式。运用该公式对某一机场牵引列车进行计算,该公式的计算结果与实际运营场景相符,证实该公式可用于工程开发和实车应用评估。

| Abstract: | Hoping to improve transport efficiency,a vehicle can tow several trailers.The minimum turning radius of the combination vehicles should be calculated at the design stage.It can be used to evaluate the running scenarios and road conditions.The paper mainly talked about calculation the turning radius of combination vehicles of towing several trailers based on no relative angular velocity between tractor and trailers,and deduced the formula of combination vehicles with 3 trailers,and deduced for n trailers.This formula is applied in an airport tractor combination vehicles and the result is compliance with reality.So it can be applied for engineering development and realistic application assessment. |
