Hi,

 

Iam simulating an impact analysis of two trolleys with four wheels on a track in Radioss. The wheels are connected to the trolley by revolute joints in the simulation and the track elements contacting the wheels were solid(i.e only two layers of track elements which contacts wheels were solid). The remaining track elements were shells and fixed in all directions using BC's. The first part of the track is inclined and we extended a horizontal track to that.(i.e inclined track_horizontal track_inclined track)

 

We expect the trolleys to come and hit at the middle. The trolleys are moving successfully but the problem here is when the trolley is moving on extended track, the track elements were getting damaged. The simulation continued with the warning:deactivated from the interface.

 

Is this because of element formualtion or stiffness? What may be the reason for this behavior?

Hi Bhavana,

 

Try increasing the GAPmin in TYPE 7 interface card and check if you still get the same warning.
