As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the … Zobacz więcej The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort. These terms apply to different operating conditions, but are related by common mechanical … Zobacz więcej Specifications of locomotives often include tractive effort curves, showing the relationship between tractive effort and velocity. The shape of the graph is shown at right. The line AB shows operation at the maximum … Zobacz więcej • Factor of adhesion, which is simply the weight on the locomotive's driving wheels divided by the starting tractive effort • Tractor pulling, bollard pull – articles relating to … Zobacz więcej • A simple guide to train physics • Tractive effort, acceleration and braking Zobacz więcej In order to start a train and accelerate it to a given speed, the locomotive(s) must develop sufficient tractive force to overcome the train's drag, which is a combination of axle bearing friction, the friction of the wheels on the rails (which is substantially … Zobacz więcej Notes 1. ^ The graphs typically show rolling resistance for standard train lengths or weights, on the level or on an uphill gradient Zobacz więcej WitrynaTractive effort, acceleration and braking. Context. For a railway to operate efficiently and safely, its locomotives should be powerful enough to accelerate their trains rapidly to …
