ISO/TS 13725:2016 specifies a method for the evaluation of the buckling load which
a) takes into account a geometric model of the hydraulic cylinder, meaning it does not treat the hydraulic cylinder as an equivalent column,
b) can be used for all types of cylinder mounting and rod end connection specified in Table 2,
c) includes a factor of safety, k, to be set by the person performing the calculations and reported with the results of the calculations,
d) takes into account possible off-axis loading,
e) takes into account the weight of the hydraulic cylinder, meaning it does not neglect all transverse loads applied on the hydraulic cylinder,
f) can be implemented as a simple computer program, and
g) considers the cylinder fully extended.
The method specified is based on the elastic buckling theory and is applicable to single and double acting cylinders that conform to ISO 6020 (all parts), ISO 6022 and ISO 10762. If necessary, finite element analyses can be used to verify as well as to determine the buckling load.
The method is not developed for thin-walled cylinders, double-rods or plunger cylinders.
The method is not developed for internal (rod) buckling.
The friction of spherical bearings is not taken into account.
NOTE This method is based mainly on original work by Fred Hoblit.[2] This method has been established in reference to the standard NF PA/T3.6.37.[1]
