Lateral Deflectionoffset deflection FC 1A

Lateral deflection is when an object (flex connector) is bent off it's centerline and both of it's ends are parallel to each other.

Lateral Deflection formula

\(\large{ l = \sqrt {6 rd \;+\; d^2} }\)

\(\large{ l_p = \sqrt {l^2 \;-\; d^2} }\)

Where:

\(\large{ C }\) = connector / coupling

\(\large{ d }\) = angular deflection

\(\large{ l }\) = hose length

\(\large{ l_p }\) = projected hose length

\(\large{ r }\) = minimum centerline bend radius for constant flexing

\(\large{ d }\) = offset distance from centerline

notes

  • When the offset motion occures to both sides of the hose centerline: \(2\) times \(d\)
  • The offset distance "\(d\)" for constant flexing should never exceed 25% of the centerline bend radius "\(r\)".
  • If the distance "\(l\)" and "\(l_p\)" is significant, take care at installation to avoid stress on the hose and braid at the maximum offset distance.
