Tire- Road Interaction doubt.

[hariharanyahoo]

I'm running a simulation using ADAMS in which,
I tired to run the vehicle over a gradient of 17 deg.
when I was changing the road friction from 0.5 to 0.4 vehicle was only able to climb upto a certain distance(say 15m).

Gradient is same in both the simulation, so C.G shifting will be same.
torque input is same.

what is the reason?

is cgz very high, and you have a fwd vehicle?

cgz means?, C.G location is not very high. and yes it is fwd.

 

[GregLocock]

Yes, CGZ is cg height. Well, without seeing your model it is very hard to tell what is wrong.

Yeah, But theoretically I would like to know how to find the gradeability of the vehicle

 

[GregLocock]

OK, so what does your hand calculation give you?

your friction does sounds rather low even if it were wet weather this could cause and issue, or amplify any other issues for sure
