Modelling vehicle acceleration

[ShivP98]

Hi everybody

I am an undergraduate mechanical engineering student and I am currently working on a project.

I need to model the acceleration of a motorcycle from 0-100mph, taking into account road friction and drag friction, the gear ratios, power/torque curve etc.



I am completely at a loss on how to do this, so I would appreciate any help I could get with this. It will be a simple flat surface so I just need a "time taken" from 0-100mph.

I have the frontal area, wheel radius, power/torque curves against RPM, gear ratios etc. Also the vehicle mass and an estimated drag coefficient.





Thanks in advance

So you need to create a free body diagram and write the equations of motion. I suggest a step by step spreadsheet type model, using a timestep of 0.01 seconds.

Cheers
