@finlay morrison If the power is constant across the rpm range it would imply torque decreases with RPM. That is maximum torque at 0 RPM and decreasing as the RPM rises if that were the case.. Of course you have to have 0 hp at 0 rpm so hp actually ramps up quickly as RPM increases from 0. But I see your point power with electric motors can be constant and high from a relatively low RPM unlike combustion engines where power is more closely proportional to RPM

In Germany it's called Superschlupf (super slip), which refers to a small amount of wheel slip providing slightly higher traction than no slip at all. Even more wheel slip (at 0:35) leads to less friction and more wear, so engineers try to avoid it. Some people call it Superschlumpf (super smurf), which is a pun.

Engineer's POV : In traction, low adhesion may cause a wheelset to accelerate more quickly than the train (wheel spin) to the point where it can damage the traction system or result in damage to the wheel and rail (rail burn). Wheel slipping occurs when tractive effort exceeds adhesive weight whereas sliding occurs when braking effort exceeds adhesive weight.. When Tractive effort is more than adhesive weight, difference in power accelerate the wheel which results into grinding action on the rail.
@josephsmith8275
2 жыл бұрын
I'm just wondering why hadn't the conductor increase the rail adhesion by adding sand. Since both steel rails and wheels have less friction coefficient. Also, Bombardier Traxx 2 and Siemens EuroSprinter are lighter in weight but have more torque which results in relatively low tractive effort than say GE Evolution series (300 kN vs > 800 kN well this also has to do with axle arrangement configurations..). Even high adhesion locomotives in the US struggles when fully loaded so why not use sand when it is available? Maybe it ran out?

Well mechanically at 0 rpm you are at 0 power. Considering slip force at the wheel rim as 4 tons (40 kN) at distance 0.5 m yields 20 kJ, when exerted for 0.2s then the power is some 100kW, so 200kW per axle. Motor efficiency is some 98% at nominal power of 1.5 MW, what means armature losses of some 30 kW. These losses are roughly the same at the standstill, so entire loco dissipates in turn 120 kW + the mechanical power when it moves.

Looks like an AC traction motor locomotive. No brushes, and AC technology controls slipping more effectively than DC. Looks like a lot of wheel "creeping" going on. EMD units will spit out sand once excessive slipping is detected (past creep) ... but AC can control slipping so effectively that the operator at times may just patiently keep lower throttle until he/she pulls away. I did not realize that Europe had sanding restrictions but the comments make sense (avoid switches). Note: earlier EMD AC tech was based on Siemens AC tech and I wouldn't be surprised if this is in fact a Siemens loco in the video? Even ABB uses similar AC tech. I think the loco and the operator are doing their jobs and letting the technology do what's best for the conditions. I tend to not second guess operators. Thank you for the video at showing what a loco can do under slippery conditions. I always admire Euro railroad operations. Peace form USA ...

There is no technical reason why DC could not achieve just the same result. But the point why you won't see it with older DC motors is, to implement it you need fast response of the traction regulator and for that you need it to operate without much filtering towards the motor itself. And in order to do that efficiently, you need rather high PWM frequencies. But once you have the technology able to use these high PWM frequencies, that is the same technology needed to implement an DC to AC (variable frequency) inverter to feed way simpler, cheaper to make and maintain, more reliable, more efficient and more robust AC traction motors. So with all that present there it would be just silly to still keep using the DC traction motors...

But in cases like this, on flat terrain, wasting sand isn't really necessary if you'll get to your desired speed anyway, even if it may take some time. You'll save it for steeper grades where you couldn't hold your speed or start moving without using sand.

@@Pferdesalami it maybe i didn't think about it, i just think if the driver are not use the sand, the train will hard to moving because the train wheels and the rails are use iron, if the weather are start rain, that will make the rails be wet and will make the train can't quicky stop or start go, so that i think the sand is very useful for train.

Having seen this video and the slippage of the wheels, it is no small task to get the train moving up to a decent speed. Considering the extremely small amount of wheel surface area touching the rail, it would seem that the solution might involve increasing this surface area during start-ups and likewise at final braking slowing down. Perhaps some kind of dual tractor belt on each truck on the locomotive between the foreword and rear wheels, which would be synced to wheel rpm could be used. This would be retractable, down from speed zero and raised at speed once the inertia of the train is in balance. Once retracted the tractor belt would be put in neutral.

There is already a solution, and has been used for quite a time: sand. Near the wheels, there is a small scope where the sand will dispense to increase friction. kzitem.info/news/bejne/pKCtmnawrWOEgqw

Increasing contact area does not increase traction force. F = μN where μ is a coefficient of friction (dependent only on properties of materials in contact) and N is weight applied Contact area isn't even in the equation so it's irrelevant. To increase traction force you'd need to either increase coefficient of friction (use rubber tires or put sand on rails, which locomotives often do) or increase weight of the locomotive. But if you increase weight inertia also increases so it will not improve stopping time.

@@ExecutionSommaire That's why it is important to stick to the equations and actual physics of what's going on. Sometimes what's "obvious" from everyday experience can turn out to be false. This is a widespread fallacy that with more contact area you get more friction. μ actually doesn't increase with area.
