Rocker Modeling and Spring Orient

Recommended Posts

Hello, I'm trying to set up a simple rocker model using 1D elements for the actual bell crank in Hypermesh and then applying the force at one end of the rocker and then attaching a spring CELAS to the other side, my issue is that for some reason the whole model is blowing up under the loadstep, I'm not sure how to use the DOF for the spring modeled in blue, but I tried to use the correct pin flags on the 1Ds for the rocker so it's constrained to in-plane. I attahed the .hm file as well, any help is appreciated, thanks.

Hi,

 

I dont see a problem with constrains. You can release the dof 4 on rocker instead of 1 which allows rotation around x axis. But I feel the model is incomplete.  Can you check?
