MAN5t truck in Deformable soil

[Prabasgarage]

Hi,

I am modelling a MAN5T truck going over a deformable terrain.  I started with the example script provided (demo_VEH_HMMWV_DefSoil.cpp). In the example script I just changed the vehicle to MAN5t. I was able to build and run the project successfully. but the vehicle keeps falling down below the terrain infinitely instead of going over the terrain. I reckon this is mainly because of the vehicle weight which is around 9 tons. when I referred the other example script(demo_VEH_M113_DefSoil.cpp), the M113 vehicle mass is seems t to be zero as I noticed this from the output panel while running the exe. 

So, Is there a way to set MAN5t truck mass? or How this problem could be resolved? I tried changing the terrain parameters as well. Doesn't help.

Thanks,

Prabanjan

Hi,

for this task a rigid tire must be used. It is actually not implemented yet for the MAN 5t truck. A handling tire does not help.

In the script when I try with a sedan car, It was working. Also what is "handling tire" referring to in chrono? can you please clarify?

[dr.ratz...@gmail.com]

Handling tires are for calculating driving behavior of wheeled vehicles. They are optimized for horizontal dynamics. Examples: PacejkaXX, TMeasy and TMsimple. Usually thes models are used on flat and rigid terrain.

As a follow up to Rainer’s answer, the reason you cannot use a vehicle with this type of tires on SCM is that only objects with a collision model can interact with SCM terrain and a handling tire model does not carry a collision model.
