Double-acting restraints with connecting nodes and gaps are used to model stop gaps along the tie bars. Stops along the tie bars are installed to restrict lateral motion at each end of the universal joint.

The following groups illustrate the method used to construct the universal joint with lateral stops shown above. Only the right-side tie rod elements are shown below.

— Standard pipe elements —

34-36 / 36-38

— Rigid flange elements —

30-32 / 40-42

— Bellows elements —

32-34 / 38-40

— Rigid elements from the pipe to the tie bar centerline —

(Normal to the pipe axis)

30-1030 / 36-1036 / 42-1042

— Tie bar elements —

1003-1002 / 1002-1001

— Restraints with connecting nodes —
