Diesel Electric Locomotive formula

AI Thread Summary
Diesel electric locomotive design involves complex engineering principles, with no simple formulas to encapsulate the process. Key design considerations include power supply, transmission systems, structural frameworks, control mechanisms, cooling systems, and regenerative braking technology. A background in mechanical or electrical engineering is recommended for a deeper understanding of these complexities. Resources like www.railroad.net provide valuable information on locomotive design and engineering. Understanding freight engine designs requires a focus on these intricate components and their interactions.

What formulas do Diesel Electric Locomotive manufactures use when designing new Locomotives? Are there any good books on the subject? Locomotive meaning train engine. I want to understand freight engine designs not passenger.

Thank you,
Kevin
 
Teams of engineers spend years designing a new model locomotive, car, truck, ship, or airplane. You won't find simple formulas to express what they do.

If locomotive design interests you, I suggest that you study either mechanical engineering or electrical engineering.
 
I worked for Electro-Motive for 20 years, the last ten in the Engine development Group. A locomotive is as complex as an airplane. Some of the separate design considerations are 1) power supply or engine; 2) transmission or power supply to the wheels; 3) platform design or the framework to support everything; 4) controls or how power is supplied to the transmission and slip control for the wheels; 5) cooling for the engine; 6) regenerative braking or using the electric motors as generators to supply power back to the grid while slowing down or to resistance grids on the locomotive.

Try visiting www.railroad.net which has a lot of information on locomotives, their design and considerations.
 
I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
