cables - and advanced support settings

Recommended Posts

Hi,

i have two questions:

1: is it possible to do cables in Inspire? I want to optimize nodes that are part of the substructure of a table that works with cables made of twisted steel-wire, so the cables should take no buckling and only tension should aplly on them, how could i do that in Inspire? i tried via the custom material settings by changing the materials properties, but without satisfying results. 

2: can i do custom supports that allow the table legs to not move in negative z-direction (because the floor stops them), but that can move upwards in positive z-direction and in x and y? because for now i can only block the z-movement both up- and downwards at the same time, not in particular. i tried by not assigning supports, but only movement limitations in z-downward direction, but then the optimization would fail

any help would be much appreciated!

phil

Hi Phil,

1: You could use the "Motion" module in Inspire. By using 3 cablelike solids, connected with sherical contacts, then will be able to submit tension only.

2.:You can activate "Degrees of Freedom" by double clicking at a support you created (there are threads inside this forum about this, as well as in the Inspire Help). To have a specific direction blocked, you will need "seperating contacts" and a contact defined between the table leg and the floor (solid or shell).

Please be aware, that for the whole model, you have to restrict anywhere every direction at least once.

 

Regards,

Felix
