Two examples of the operator durability calculation are shown below:
The durability of the
product is influenced by
the severity index:
with reference to Tab.
1.1, according to the type
of piston, the weight and
the width of the wing
and the use conditions,
different corrective fac-
tors were estimated, the
sum of which influence
the operator durability
(see Tab. 3.2).
