A moving load

A moving load

A moving load

(OP)
Hi,

I am making a simple beam with two supports (no dislocation in y axis) and I nedd to creat a load that moves in x axis.
Could you help me??

Thanks

RE: A moving load

Define a series of AMPLITUDEs that describe the load variation with time at each x nodal position along the beam

Then apply loads as follows on each respective node along the beam:
*CLOAD, AMPLITUDE=AMP1
NODE1, 2, 1.0
*CLOAD, AMPLITUDE=AMP2
NODE2, 2, 1.0
*CLOAD, AMPLITUDE=AMP3
NODE3, 2, 1.0
etc

where 'NODE1'.... are the node sets or node numbers.

The AMPLITUDEs will progressively increase and then decrease the load on each node.
 

RE: A moving load

Another way might be to create a rigid body that has contact with the beam, and then move the loaded rigid body along the length. Might take longer to run though.
