ABAQUS Vehicle bridge interaction for 3d roughness surface

[han_cyuan]

I now want to use the ISO8608 regulations to generate 3D road surface roughness. Is there any way to do this? And how to set the contact settings between my wheels and the rough surface?

 

[FEA way]

There is a plug-in for that. You can find it in DS Knowledge Base - article QA00000125911 "Abaqus/CAE Plug-in to Generate 2D/3D Rough Surface by Random Surface Generation Algorithm or by Importing Measured Profile Data".
