Description

一种用于交通运输车辆的助力装置 技术领域
本发明涉及陆路交通领域, 特别涉及一种用于交通运输车辆的助力装置。 背景技术
目前, 釆用火车、 汽车、 地铁、 轻轨等交通工具进行客运及货运的运输 方案已经在经济发展中占用了很重要的地位。 采用上述交通工具可以方便、 快捷地实现了客运和货运的经济发展要求, 但同时也带来了大量的能源消耗, 以及环境污染的问题。
为了尽量减少能源的消耗, 现有技术下, 往往会在交通运输车辆的动力 系统、 车厢材质等方面进行技术改进, 以及在道路环境方面进行改善, 这样 做虽然取得了明显的节能效果, 但其耗费的成本也是可观的。
有鉴于此, 需要提供一种新的减少能源消耗的方法, 在节省能源的同时, 将实现成本维持在一个较低范围内。 发明内容
本发明实施例提供一种用于交通运输车辆的助力装置, 用以在节省能源 的同时, 降低实现成本。
本发明实施例提供的具体技术方案如下:
一种用于交通运输车辆的助力装置, 包括一组助力挡板, 每一个助力挡 板用于设置在所述交通运输车辆的顶部, 并沿车辆行进方向与车体形成 [0, 9] 度的攻角。
一种交通运输车辆, 包括: 一组设置在所述交通运输车辆的顶部的助力 挡板, 每一个助力挡板在车辆行进时沿车辆行进方向与车体形成 [0, 9]度的攻 角。 本发明实施例中, 利用空气动力学原理, 在高速运行的火车、 汽车等陆 路交通运输车辆上, 加装类似飞机翅膀的装置, 使其获得额外的升力, 减少 了车辆与铁轨、 地面之间的摩擦阻力, 从而大幅度降低了车辆在电力、 油料 方面的能源消耗, 也减少了对环境的污染, 同时, 也降低了整体方案的实现 成本。 附图说明
图 1为本发明实施例中安装有翅膀的车厢结构示意图
图 2为本发明实施例中翅膀受力原理示意图;
图 3和图 4为本发明实施例中升力系数和阻力系数分别与攻角之间的关 系示意图;
图 5为本发明实施例中车辆低速行驶时翅膀角度示意图;
图 6本发明实施例中车辆制动过程中翅膀角度示意图。 具体实施方式
为减少交通运输车辆在行驶时所消耗的能源 (如电力、 油耗), 本发明实 施例中, 利用空气动力学的原理, 在栽重量大, 高速运行的交通运输车辆(如 火车、 汽车等陆路运输工具) 的车顶加装若干助力装置, 以下实施例中将该 装置称为"翅膀", 本实施例中, 所谓翅膀, 即是一組助力挡板, 每一个助力挡 板设置在所述交通运输车辆的顶部, 并沿车辆行进方向与车体形成 [0, 9]度的 攻角。 这样, 交通运输车辆在高速运行时, 便可获得一定的升力, 相当于减 轻了交通运输车辆的载重量, 从而可以减少其牵引电机、 发动机的电力、 油 料的消耗, 进而达到节能, 减排, 环保的 ϋ的。
另外, 如果把 "翅膀 "与制动控制系统相配合, 在机车制动时, 可以通过把 "翅膀"的角度调整为 "负角度",把升力变为空气阻力, 达到协助制动的目的, 以减少制动距离, 一方面可以并减少因此产生的制动刹车系统的磨损, 另外, 也可以减少紧急情况下的危险概率。 下面结合附图对本发明优选的实施方式进行详细说明。
现有技术下, 飞机的翅膀产生的升力可以把飞机托起升空, 同理, 把这 个原理运用到高速行驶的陆路交通运输车辆上, 就可以利用产生的升力来抵 消一些载重, 从而降低交通运输车辆与地面或铁轨间的摩擦阻力, 进而达到 减少能源消耗的目的。
基于上述原理, 参阅图 1和图 2所示, 本发明实施例中, 以火车为例, 在火车顶部安装翅膀后,将翅膀获得的升力设置为 L,将翅膀获得的空气阻力 设置为 Fd, 将翅膀以及安装时使用的相关设备的总重量设置为 G, 并且假设 铁轨与车轮的摩擦系数 μ=0.1 (现有技术资料提供的数据), 那么上述各参量 满足以下公式显示的关系时, 本发明的技术方案便是可行的:
( L - G ) μ - Fd X)
研究空气动力学中关于机翼部分的内容可以得知: 不同机翼形状, 不同 攻角 (攻角, 又称 ANGLE OF ATTACK, 在本发明实施例中是指翅膀与水平 方向产生的角度)的动力学特性是不同的, 其升力系数, 阻力系数都不一样。 本发明实施例中, 考虑到制作工艺的筒单性, 制作成本以及空间局限性等因 素, 较佳地, 采用 "平凸型" 的翅膀, 如图 1 所示, 翅膀靠近车厢顶部的一 面形状为平型, 远离车厢顶部的一面形状为凸型 (即该 "平凸型" 的翅膀类 似机翼的表面结构), 该翅膀的形状、 尺寸大小及受力面积可以根据具体应用 环境而自行调整设计, 只要其展弦比小于设定阈值即可以达到理想的技术效 果。 所谓展弦比(Aspect Ratio ), 是飞机空气动力学的专有名词, 其定义为机 翼的翼展平方与机翼翼面积的比值:
其中 AR为展弦比, b为翼展长度, S为翼面积。 采用小展弦比(即设置 展弦比小于设定阈值)是因为翅膀的形状、 尺寸受到车厢宽度的限制, 但可 以通过加装多个 "翅膀"来加大升力膀,各翅膀之间的间距最佳约为 50公分。 另一方面, 本实施例中, 兼顾技术效果与实现成本, 较佳地, 翅膀的材 盾可以采用铝合金或复合材料等。
参阅图 3所示, 图 (a )表示升力系数 CL与攻角之间的关系, 图 (b )表 示阻力系数 CD与攻角之间的关系。 从图 3可以看出, 随着攻角的增加, 升力 系数与阻力系数均在增加, 但不是线性增加, 因此, 翅膀与车顶之间的角度 需要控制在一定范围内, 才可以达到理想的效果。
从上述公式(L - G ) μ - Fd X)可看出, 升力 L与阻力 Fd之间的差值越 大, 减轻载重量的效果越好, 参阅图 3和图 4所示, 根据实验数据得出, 攻 角在 [0, 9]度的范围内时, 翅膀获得的升力是递增的, 而在大于 9度时, 翼型 上表面的气流会严重分离, 会引起的升力剧降现象, 称作失速现象。 因此, 采用 [0, 9]度的攻角均可以实现为车辆 "减重" 的技术效果, 而且在攻角为 9 度时, 升级取最大值, 且升力 L与阻力 Fd的差值最大, 可见, 最佳攻角为 9 度, 即此时 "减重" 效果最佳。
下面以攻角为 9度攻角为具体的交通运输车辆为例对翅膀的 "减重"作用 进行介绍。
假设地面的空气密度 p =1.29kg/m3
翅膀的升力 L的计算公式为:
L = l/2 p V2 S CL
其中, L是升力, S是翅膀平面的面积, V是车辆在空气中行进的速度, 而 P是空气密度, CL为升力系数。
翅膀的阻力 D的计算公式为:
D= 1/2 p V2S CD
其中, D是阻力, S是翅膀平面的面积, V是车辆在空气中行进的速度, 而 P是空气密度, CD为阻力系数。
在一个实施例中,假设动车组每编组有 8组车厢,每车厢为 24米长, 2.85 米宽。 每个翅膀的平面面积为 2.8m (沿车厢宽度方向) X 1.8m (沿车厢长度 方向) =5.04m2, 每个翅膀间隔 2米), 动车共设计加 48个翅膀, 其总翅膀面 积为 5.04m2 x 48=241.92 m2, 通常列车与铁轨的摩擦系数为 μ=0.1。
当动车组时速为 200公里时(不计风速影响), 从图 4可看出, 在 9度攻 角时, CL=L48,CD=0.08, 升力 L与阻力 Fd的差值最大, 此时, 动车组可以 节省的能源最多的。
根据上述升级与阻力的计算公式可以得到:
L=l/2pV2S CL=0.5*1.29*55.562*241.92*1.48=712,880(N)
