Tractive effort requirements
Tractive effort requirements
(OP)
Has anybody got the calculation method for determining the tractive effort required to counter-rotate a tracked machine on various surfaces with varying track length and track pitch?
Thanks...

RE: Tractive effort requirements
If so then i think the best way to look at it would be to take a force couple, modeling the vehicle as a circle with tangental force components.
You would need to set a target rotational speed (omega [rad/s])
Its probably best to treat it like a spinning disc and calculate the torque by T=I.alpha
where T=torque, I = moment of inertia (need to also calculate this, different formulas for different shapes), alpha=angular acceleration (calulate by differentiating angular velocity (omega) wrt time).
Would be interested to see what others think...

RE: Tractive effort requirements
Unless you are trying to optimize the design of a particular machine, I would look at other machines of similar size, weight and usage. On some machines the engine HP is more determined by not getting stuck in the mud than anything else.
I know it's not a very good answer, but if you want more help you need to provide more details.
