tractive efforts
1
牵引力, 拉力
the pulling or hauling force exerted by a locomotive or vehicle
Tractive effort is the force that a train's engine or locomotive generates to pull or move the train along the track. It is a measure of the engine's ability to overcome resistance, such as friction or slope, and is crucial for determining how much weight the train can carry. The greater the tractive effort, the more powerful the locomotive, allowing it to pull heavier loads or move at higher speeds. This effort depends on various factors, including the design of the engine, the track conditions, and the weight of the train.
- The steam engine's tractive effort enabled it to pull heavy loads across long distances.
蒸汽机的牵引力使其能够长距离拉动重物。
- Modern electric trains rely on their powerful motors for high tractive effort, ensuring efficient movement of freight.
现代电力机车依靠其强大的电机实现高牵引力，确保货物的高效运输。
- Engineers often calculate the tractive effort needed based on the weight of the train and the gradient of the track.
工程师们经常根据列车的重量和轨道的坡度来计算所需的牵引力。
- In mountainous regions, trains require more tractive effort to ascend steep inclines.
在山区，火车需要更多的牵引力来攀登陡坡。
- Diesel locomotives are known for their robust tractive effort, making them suitable for both freight and passenger services.
