http://www.f1technical.net/news/2577 The Imola circuit that hosts the San Marino Grand Prix, presents the teams with unique challenges in order to maximise their performance over the race weekend. There are few quick corners, many short straights, a relatively smooth track surface and, of course, the famous kerbs that are an integral part of the racing line. Here’s how the R26 will be prepared to cope with the challenge. Imola本身包含数个高速湾 多个短直道 跑道面相对较为平滑 路肩(路沿石)是车手们跑这个场地时常会运用在跑线中的要素 Chassis Suspension: Imola is famous for its kerbs, and particularly the challenges of the Variante Alta and Variante Bassa chicanes. We must find the right compromise between the optimum soft suspension settings for riding the kerbs, and the stiffer set-up we naturally want to ensure the car has a good change of direction in these chicanes. Some bodywork elements such as the diffuser and front wing, can be damaged by running over the kerbs, and we have to carefully monitor their condition throughout the weekend. 在这个场地 因为运用路肩的比例较高 悬挂的设定必须兼顾吃路肩时所需的柔软度和转向时所需的硬度 部分较贴近地面的部件如前翼和导流器可能会因为行经路肩而磨损 这也是必须要格外注意的地方 Aerodynamics: We use relatively high levels of downforce, in order to give the drivers as much confidence as possible in the car. The short straights mean overtaking is difficult, so a top speed deficit is not a significant penalty if we decide to add more downforce. 为使车手在操控上更能有自信及有效掌握 因此下压力采相对较大之设定 因直线道长度较短 本来就不易用以超车 所以因下压力调高所造成车辆之极速不足 并不会造成太大的影响 Tyres: The circuit includes numerous phases of hard acceleration from low speed, which means traction is at a premium and we need to monitor carefully rear tyre wear. However, Imola is not a particularly abrasive circuit, meaning the levels of degradation are generally lower than those encountered at many other circuits. 这个场地中有不少地方需要从低速做急加速 因此循迹性也就格外重要 也因此须要密切注意後轮的磨耗状况 但整体而言Imola是一个轮胎磨耗相对於其他许多赛道较小的场地 Reliability: The violent use of the kerbs around the lap puts the cars under particular strain, and Imola often sees a high retirement rate. As well as the vibrations generated by using the kerbs so aggressively, the transmission experiences significant ‘shock loads’ when the cars land with their wheels spinning, which can often lead to failures. Imola向来是车辆退赛率较高的场地 若车手在驾驶上拼过头(按:过度使用路肩导致车辆震动过大) 则会让传动系统因受到地面反作用力之冲击而发生故障 Engine Performance: The engine is put under particular strain at Imola. We need good torque to launch out of the slow corners, and the hard acceleration phases mean that the engine’s outright power is an important factor. 73% of the lap is spent at full throttle, which is among the highest values of the season. However, the longest period spent at full throttle is relatively short, which relieves the pressure on moving parts such as pistons; counter-balancing this, though, is the fact that the generally cool temperatures equate to high air density, meaning the engine develops more power and is under greater strain. 总体而言本站对引擎性能是较为严峻的挑战 因为需要输入较大的扭力以应付车辆出低速弯後的急加速 并且单圈中有约73%的比例在全油门状态 但持续全油门的时间却并不长 因此对於可动部件仍有缓冲作用 相对较低的气温 较高的空气密度可让引擎有更佳的马力输出 Revs: The average engine speed at this circuit is relatively high, but the main danger for the engine comes from potentially over-revving when the car is launched over the kerbs and the driven wheels lose contact with the ground. We need to manage the risk of over-revving as well as possible, by judicious use of the rev limiter, without sacrificing performance over a flying lap. However, in race conditions, excessive use of the limiter can generate potentially harmful vibrations for the engine, so we may ask the driver to modify his shift points or adjust his line to adapt to this constraint. 引擎转速在本站是相对较高的 而可能造成超转的原因来自吃路肩时车轮与地面没有接触 却又在此时急踩油门所造成 因此在非正赛时会适当运用限转 但正赛时若过度限转则会产生振动伤引擎 因此这部分需要靠车手掌握换档时机及跑线 Source Renaultf1 翻译/注解 : 伪首席测试车手 -- ██████ █ ██◣ ◢█◣ ██◣ ◢██◣ ███ ██◣ ██████ █ █ █ █ █ █ ◣ █ █ █ █ █ ██████ █ ██◤ █ █ █ █ █ █ ██◣ █ ◤ ██████ █ ██◣ ████ █ █ █ █ ██◤ ██▌ ██████ █ █ █ █ █ █ ◤ █ █ █ █ ▉ ██████ ███ ● ██◤ █ █ ██◤ ◥██◤ ███ █ ▋ --
