我们有理由相信,这一届北美车展是林肯品牌向多元化发展的开始。除了有Concept C亮相之外,林肯还带来了一款定位为Crossover车型的MKT。同Concept C概念车型一样,MKT的家族化特征表现明显,而外形的设计也稍显魁梧,以追求Crossover的风格定位。 相似文献

林肯,这个同美国总统同名的美国豪华品牌将在2014年10月正式进入中国,首次引入两款车型,一款豪华轿车一款豪华SUV,对于这两款车,你可千万不要用看加长林肯的眼光来看待它们。林肯宣布进入中国的两款车分别是MKC和MKZ,对于中国人来说,这两个名字确实有些难记,我自己也总是在每次说之前多想几秒。MKC是SUV,MKZ是轿车,目前林肯在美国销售的还有一款大型SUV——MKX,加上之前同中国贸易协定引进的全尺寸SUV领航员,大家熟悉的林肯目前在售的就是这四款主力车型。 相似文献

近日,林肯发布了一款全新的概念车,给出了林肯对于未来汽车的定义.林肯Anniversary概念车具有非常强的未来感和科技感,它是一款定位于两门大型轿跑的概念车.
这款概念车运用了相当数量的圆润线条,前脸和车身看上去都非常圆润和谐,不同于大部分概念车喜欢用直角以及锋利的线条.林肯Anniversary概念车的车身采用了一体化设计,车门和门把手都做了隐蔽式处理,车门框也采用了隐藏式设计.整个车身侧面造型低矮修长,超长的车头加上圆润宽大的车尾让整款车看上去像猎装跑车. 相似文献

This paper investigates which different steering reactions are necessary by the driver to avoid obstacles driving a car with or without a trailer. For car and trailer complex 3D-models with nonlinear tyre characteristics are established. The driver modelling extends the well-known 2-level concept with an overruling 3rd level, that will be activated, if unexpected large driver reactions due to the large local path deviations are necessary. The results, comparing these different driver models for car and car–trailer, clearly show the consequences and advantages of the incorporation of a third, extensive reaction level and especially its importance for the car–trailer combination. 相似文献

This paper presents the active case of a variable stiffness suspension system. The central concept is based on a recently designed variable stiffness mechanism which consists of a horizontal control strut and a vertical strut. The horizontal strut is used to vary the load transfer ratio by actively controlling the location of the point of attachment of the vertical strut to the car body. The control algorithm, effected by a hydraulic actuator, uses the concept of nonlinear energy sink (NES) to effectively transfer the vibrational energy in the sprung mass to a control mass, thereby reducing the transfer of energy from road disturbance to the car body at a relatively lower cost compared to the traditional active suspension using the skyhook concept. The analyses and simulation results show that a better performance can be achieved by subjecting the point of attachment of a suspension system, to the chassis, to the influence of a horizontal NES system. 相似文献

采用生态足迹分析方法,对我国2002年到2007年的轿车生态足迹进行核算,构建了轿车保有量以低、中和高3种速度增长的情景,并分别对每一种情景与对应的基准情景进行对比分析.分析结果表明,随着柴油轿车比例的不断上升,轿车生态足迹与基准情景相比有所降低,但是由于轿车保有量的持续高速增长,到2030年,我国轿车生态足迹将达到2010年的6倍以上.最后就我国轿车产业将要面临的严峻的能源和环境压力提出了几条对策. 相似文献

针对概念设计阶段的车身结构轻量化设计,提出了一种可实现车身多材料结构设计的分层迭代优化方法。该优化方法的设计变量中,除常见的板厚、材料外,还包括装配设计中的拓扑连接,以实现“将合适的材料用在合适的部位”的要求。分层迭代优化的第1层以拓扑连接为设计变量,采用图分解和NSGA-II对车身装配拓扑结构进行多目标优化,最大化车身弯扭刚度和1阶固有频率;第2层对板厚和材料进行多目标优化,最小化车身质量和材料成本。最终采用基于模糊集合的评分公式选定综合最优解,实现了考虑成本的车身结构轻量化设计。 相似文献

Because Formula cars are lighter than ordinary cars, the optimal settings for this type of car are thought to be different
from those of a ordinary car. The front and rear weight distribution ratio of a vehicle is an important parameter that exerts
a significant influence on critical cornering. The tendency of a ordinary car to under-steer during critical cornering is
determined by the front and rear weight distribution ratio of the vehicle. Specifically, when the front of an ordinary FR
(front-engine, rear wheel drive) vehicle is slightly heavier than the rear, the car tends to understeer during critical cornering.
However, the optimal weight distribution ratio for critical cornering is not obvious for a formula car because of its lightness.
This observation was investigated using a driving course similar to a real driving course to perform a maximum speed cornering
simulations. It was found that a front to rear weight distribution ratio of 40:60 resulted in the fastest lap time. This ratio
also gave the best results in the maximum-speed driving experiment performed using a driving simulator. Moreover, the maximum
lateral acceleration during turning, the driving force, and the load movement of the inside and outside wheels was calculated
using experimental driving force data and the concept of a tire friction circle. As a result, driving mechanics have been
determined for a vehicle having a front/rear weight distribution ratio of 40:60 while traveling at maximum speed. 相似文献
