see the attached image.
5-10 rigid element - it is clear trunnion pipe leg+ radius of pipe.
10 c node 15
restraint x,z- not clear to me . For what reason this restraint.
10 hanger with c node 15- it is clear.
Why +Y at node 20 normally trunnion not fixed to spring top load flange. Actually friction occurs that point.
But here it is fixing point btn steel & spring box base plate.Is this correct approach.
