Obstacles/road barriers & trench crossings ...

Can Vortex Studio simulate situations like obstacles/road barriers & trench crossing for vehicles w/ low velocities? If so, are there any validation studies/reports/analyses etc.?


Best Answer

Yes, Vortex Studio has all these capabilities to a high degree of accuracy. The multi-body modeling approach supports dynamics response for contact between any part of the vehicle, including the chassis, any accessories on the vehicle (turret, etc.) and with any modeled object in the simulation, including terrain of arbitrary shape, bridges, underpasses, buildings and other vehicles. You can check out the Defense Vehicles scene in the Vortex Studio samples, it contains many such obstacles to drive over.

The general terrain geometry is modeled as a triangle mesh, which can be imported from a variety of formats or a heighfield or Discrete Elevation Model.


Obstacles can be represented either as part of the terrain triangle mesh (like the rocks above), or as separate objects, either static or dynamic. Dynamic obstacles are modeled using the multibody engine and can contain articulations, etc. Contact properties (ex. stiffness, damping, friction) may be given to determine collision response behavior. 


Unfortunately, no data is publically available since these capabilities were verified in the context of defense project work, and we are not at liberty to disclose this information. We do have a more general Verification & Validation document in the Vortex Studio package. If you have a valid Vortex Studio license, it should be available for download on your account page.
