Basic Dynamics estimations with and without MDO

Hi alls,



I have to simulate (with MDO) a vehicle that rolls on rail (about like a
train).

The aim is to estimate speed, acceleration, power consumption.



In order to validate my Creo/MDO models, I would like to make basic calculus
outside Creo.



I have to consider :

- Vehicle weight

- Rails slopes

- Wind speed (I've already made a CFD study and I know wind forces)

- Rolling resistances

- Friction in wheels bearings.



I would like to analyze this vehicle in several cases :

- Starting from a null speed in a slope

- Rolling on horizontal plane (need to add energy)

- Using friction brakes.



So, I'm wondering if there are some simple software, web-site explanations.
that could explain how to estimate physical quantities I'm looking for.

I think I've learn this when I was younger but it's so far.



Any link or explanation would be very appreciated.



Thanks,



GB
