F1赛车前定风翼工作原理介绍

Front wing aerodynamicsBy Steven De Groote on 18 Jun 2003, 16:27The front wing of a Formula One car creates about 25% of the total cars downforce. Although this only occurs in ideal circumstances. When a preceding car runs less than 20m in front, the total downforce generated by the front wing may become as little as 30% of its normal downforce. Although this reduce of drag (because the air pressure is lower behind a car's rear wing), enables higher speeds at the end of straight, it significantly hinders the pursuing car in corners, as he cannot take these at normal speeds. This problem mostly occurs in fast corners, and is one of the most important reasons of the overtaking problem currently in Formula One. It is therefore a hard job to create a performing front wing, even more because disturbing the airflow too much will affect the rest of the car's aerodynamic efficiency too.Regulations3.4 Width ahead of the rear wheel centre line :3.4.1 Bodywork width ahead of the rear wheel centre line must not exceed1400mm.3.4.2 In order to prevent tyre damage to other cars, the top and forward edges of the lateral extremities of any bodywork forward of the front wheels must be at least 10mm thick with a radius of at least 5mm.3.7 Front bodywork height:All bodywork situated forward of a point lying 330mm behind the front wheel centre line, and more than 250mm from the centre line of the car, must be no less than 100mm and no more than 300mm above the reference plane.3.17.1 Bodywork may deflect no more than 5mm vertically when a 500N load is applied vertically to it 700mm forward of the front wheel centre line and 625mm from the car centre line. The load will be applied in a downward direction using a 50mm diameter ram and an adapter 300mm long and 150mm wide. Teams must supply the latter when such a test is deemed necessary.Front wing designA regular front aerofoil is made as a main plane running the whole width of the car (almost at least, limited by FIA regulations) suspended from the nose. Onto this are fitted one or more flaps which are the adjustable parts of the wing. On each end of the mainplane there are endplates. These make sure the airflow passes above and beneath the wing rather than around it. In recent years theseendplates have played a crucial role in influencing the airflow around the front tyres, especially after the rule changes at the beginning of 1998 (wheelbase made smaller from 220cm to 180cm). These changes made front wing airflow interfere with the rotating airflow around the front wheels.Article 3.17 has been introduced during 1998, after teams started experimenting with bending front and rear wings. When Ferrari introduced such a front wing at the end of 1997, it was produced in such a way that the wing would flex under aerodynamic loads. This means that as the speed increased, a force was produced that pushed the wing towards the ground. By means of a ground effect, this was particularly interesting for front wings because if would increase downforce at high speeds without an increase of drag. As rear wings began to fail and flew off during races, the FIA thought it was time to act and added 3.17 to the technical regulations of Formula One.At the beginning of 2001, front wing regulations had changed in such a way, that the wing should be 100mm above the ground at least, instead of the 40mm until then. The FIA introduced this change to limit the cornering speeds of the cars. The idea was to decrease the ground effect that was generated by front wings close to the ground, working just like a diffuser.Immediately at the start of the season, Ferrari introduced a front wing that was bent down in the center line or the car. This new concept makes a handy use of a little hole in the regulations. The whole is the result of a rule, added in 1994, where the wooden bottom made it's entry. This wooden plate can be hung up as low as possible to the ground. As this plate is 50 cm wide, it was not foreseen that the front wing may be placed that low to the ground in 25cm at each side of the center of the car. Since the introduction by Ferrari, more and more teams have adopted the idea of curved front wings, with them also McLaren and Renault (see picture).Though the reason that McLaren didn't make any of those changes until 2002, might have to do with the curve of the front wing before the change of regulations. It was namely curved up in the middle, so that the inner side washigher above the ground then both outer sides of the front wing. This type of wing is mostly useful on fast tracks where not much downforce is needed. It is there that airflow in the centre of the car can be more used by the diffuser in the back instead of lifting it up and create downforce in the front.End platesAs some of the air that is needed to generate the front wing's downforce interferes with the rotating air around the front wheels, F1 teams have been developing the end plates from a simple plate to an integral part of the wing. To overcome the main problem of turbulence around the wheel, McLaren, andlater Ferrari made in 1998 the inside edges of the front wing endplates curved to direct the air between both front wheels. One year after, all teams had adopted this technique to maintain front wing efficiency. Some other teams decided to decrease the width of the main plane just to the width between the front wheels. This left some room for extra wings and flaps, which caused the beginning of intensive end plate research. In 1998 changes were so radicalthat Ferrari produced six different designs of front wings throughout 1999, in order to reclaim the lost downforce by regulation changes.。

解析双叉臂独立悬挂技术

解析双叉臂独立悬挂技术在常见的集中独立悬挂结构中,双叉臂式悬架被公认是操控性最出色一种,绝大多数的性能跑车乃至于F1赛车使用的都是双叉臂的悬架结构。
那么下面就带大家一起了解一下这种最具有运动基因的悬挂形式。
由于叉臂长的很像许愿骨,所以得名doublewishbonesuspension(双愿骨式悬架)。
双叉臂悬挂也叫做双A臂悬挂或者双摇臂悬挂,属于双横臂悬架中的一种,英文名为doublewishbonesuspension(双愿骨式悬架),这个名字据说来源于西方圣诞节上一种吃火鸡的习俗,当人们开始吃的时候,首先要对火鸡身上一根V字形的骨头许愿,而这根骨头就叫许愿骨(Wishbone)。
而因为在双叉臂悬架结构中的A臂或者是V臂和许愿骨的形状非常相似,故得名双愿骨(doublewishbone)式悬架。
packard120是首款使用了双叉臂悬挂的量产车双叉臂悬架最早出现于上世纪30年代,当时的方程式赛车已经开始使用类似双叉臂的悬挂结构,而1935年,来自美国底特律的packard在旗下车型packard120上首次使用了双叉臂悬挂,作为当时豪华汽车的代表,pachard创造性的在量产车上首次使用了这种结构复杂的悬架,从而提升车辆的操控性能。
时至今日,双叉臂悬挂仍旧在除了各种性能跑车、豪华轿车和大型SUV上广泛使用。
关于双叉臂悬架起源的误区:此前,在网络上流传着一种错误的说法,认为双叉臂悬挂的灵感来自于麦弗逊悬挂,是由麦弗逊悬挂改进得来的。
这个说法的根据就是双叉臂悬挂和麦弗逊悬挂都拥有相似的A字形下摆臂和支柱式减震器的结构,所不同的是双叉臂结构在减震器上方还增加了连接车轮的A臂。
不过在事实上,双叉臂悬挂和麦弗逊悬挂并没有任何亲缘关系。
为何这么说呢?前面我们说过,早在上世纪30年代,双叉臂悬挂就已经开始在赛车运动上大量使用,而1935年则首次被使用在了量产的商品车上,而麦弗逊悬挂开始研发的时间为上世纪30年代中期,其设计灵感则是来源于飞机的起落架,而首次出现在商品车上则是在1949年的福特Vedette上。

Technical analysis - FRIC suspension systems explainedMcLaren racing director Eric Boullier recently confirmed that the teams were sent a technical directive from the FIA's race director Charlie Whiting following the last race in Great Britain regarding the legality of the Front-and-Rear Interconnected Suspension (FRIC) systems used on most cars. The governing body is understood to believe that some of the systems currently being used may contravene the technical regulations, raising the possibility of them being banned outright. But what exactly is FRIC suspension and how does it work? Read on to find out…A Front-and-Rear Interconnected Suspension (FRIC) system, as shown on the 2013 Mercedes F1 W04Front-and-Rear Interconnected Suspension (FRIC) systems have been around for many years; for example Ferrari were one of several teams to run a cable-based system in the 1970s. However, the hydraulics-operated technology of today is much m ore complicated and can be ‘plumbed’ in many different ways - it can cross link the front suspension, cross link the rear suspension, link the front and rear suspension, or - in the most sophisticated systems - link all four corners diagonally for maximum performance benefit.But why do so many teams use FRIC systems? The first and most important reason is that it can help to generate more underbody downforce as it gives a degree of control over how the car changes attitude at speed when downforce is increasing. It also allows some degree of ride height/rake control when the car is braking.Formula One cars produce up to 6G of braking force which means that the load transfer from rear to front is around 300 kilos. This extra weight - there for around one second on corner approach - not only increases the load on the front tyres, it also decreases the load on the rear tyres, and this makes the rear unstable under braking and on corner entry.The other problem with this weight transfer from a performance point of view is the aerodynamic changes that take place when the car changes attitude. The weight transfer causes the front of the car to get closer to the ground and the rear to get further away and, with normal aero-maps, this will increase front downforce and decrease rear downforce, adding to instability.If you have a system - like FRIC - that can use the increased load on the front suspension under braking to lower the rear ride height then it is possible to have a much more aggressive underbody and front wing aero-map, which in turn increases the car’s overall downforce and therefore grip.If the system is sophisticated enough to also allow fluid to be displaced diagonally across the car it also allows the car to be run with much softer suspension without the penalty of increased roll. Again, this will help with overall aerodynamic grip and allow the driver to be much more aggressive over the kerbs.Most teams keep these sort of systems under wraps so it is difficult to define all the components in detail, but it general they consist of four actuators, one on each corner of the car (the locations of which are indicated by arrows 1 and 2 in this drawing of the 2013 Mercedes F1 W04), with hydraulic pipework connecting the four suspension units to a main accumulator (indicated by arrow 3) which is situated next to a control manifold (indicated by arrow 4).The main accumulator and the valve system within it acts as the brains behind the system. However, the systems utilised by each team will vary considerably with regard to how they use the displaced hydraulic fluid from each actuator andwhether they feed it through to another actuator either diagonally or inline.In the rear detail image you can see two black actuators with the pipe work linking them to a central accumulator (indicated by the red arrow). As you can see in the main image, pipework then links this to the main accumulator.In the front detail view (to the right of the main image) you can see the front two actuators inside the chassis (top two red arrows) with two pipes coming from them (middle pair of red arrows). These pipes are used to bleed and pressurise the system with dry break couplings (the lower pair of red arrows).In the lower detail image, the forward two red arrows show the positioning of the main accumulator and control manifold linking the front and rear suspension, whilst the two rearward red arrows show the positioning of the right-rear actuator and central accumulator.。
