Body rested on rigid plane

Recommended Posts

If there are tires which are rested on the ground. To simulate this, I was thinking of considering ground as a rigid plane over which wheels are placed. What type of connection should be considered for line contact between tires and ground? Wheather a tie contact can be considered?

Hi dragon,

 

tires in contact with the ground under gravity would result in a contact patch over an area.

There are two approaches to model such behaviour:

 

1. infinite rigid wal (Analysis>>Rigid walls)

2. Type 7 –  ( General Purpose Interface )

 

a.       Multi-usage impact interface, modeling contact between a master surface and a group of slave nodes.

b.       General purpose interface and can simulate all types of impact between a set of nodes and a master surface.

 

A tied contact Type 2 – ( Tied Interface ) would not model the contact the most accurately.

 

a.       Tied Contacts define an interface that kinematically connects a set of slave nodes to a master surface.

b.        This interface is used mainly for the connections.

c.        It can be used to connect coarse and fine meshes, model spot-welds, rivets, etc

HI,

 

I think, to start with use RIGID wall with the tire which defines contact between the rigid and tire. 

 

Yeah, as Ivan said, type 2 contact is not suitable.
