Hi all,
I'm currently working on existing flowlines with existing constant spring hangers in the system. I would like to know how to correctly model a pre-defined constant spring hanger using YSPR. I have read the CII manual but when i apply it, the results doesn't make sense. In my system, i have a constant spring hanger with total travel of 368mm and load of 25000 N. In the Restraint field, my "x" is 368mm and my F is 25000 but i leave a blank for 'Stif' since it is a constant spring hanger. However, after running the analysis, my displacement is 0 in Y direction and it happens to all my spring hangers. I don't think all my spring hangers bottom out. Please advice where did i do wrong
