rigid links!!!

[r33tom]

Hey guys, i was wondering of anyone knows more about rigid links and how they work in pro e mechanica.


Heres what i have done; i have a datum point which sits in space and i have a point force on this datum point. and i place a rigid link from that datum point to a surface on another object. i was wondering whatand where i place restraints on etc to kinda make it realistic. i dont think i have provided enough info, but the case is pretty much a contact patch of a tyre (with a force on it) rigided linked to the inside of the upright where the bearings sit.





thanks tom

Rigid links are exactly that - rigid. You cannot make them flexible. Any geometric entity you select to apply them to will also become infinitely rigid itself (curves and surfaces). So be careful using them on large surfaces or long curves. You can use beams and select the correct properties to make the force act through the beam to the bearing hub in order to capture some amount of flexibility. To do what you have described you've tried already through a simplified manner, place a "TLAP" (Total Load At Point) on the point in space and connect it to the hub/upright surface. This will create the correct momentand force based on the point's location WRT the hub/upright surface without any links of any kind.


Hope this helps,
