PRODUCT DURATION
The duration and average economic life of the product. The value of
duration is strongly affected by the fatigue index of the manoeuvres
performed by the automation: i.e. the sum of all factors that contribute
to wear of the product (see Table 1).
The estimation of duration is made on the basis of the design calcula-
tions and the test results performed on prototypes. In fact, as it is an
estimate, it does not represent any guarantee regarding the effective
duration of the product.
To establish the probable duration of your automation, proceed as
follows:
01.
Calculate the fatigue index
by adding the percentage values of the
items present in
Table 1
.
02.
In
Graph A
of the value just found, trace a vertical line that crosses
the curve; from this point trace a horizontal line until the “manoeu
-
vre cycles” line is crossed. The value determined is the
estimated
duration of your product.
Example of the duration calculation of an LFAB(...) / XLFAB(...)
gear motor. Refer to Table 1 and Graph A:
1)
- Panel length: 3 m
2)
- Panel weight: 500 kg = fatigue index: 30%
3)
- Installation in windy areas = fatigue index: 15%
4)
- Does not have other elements of fatigue
Total fatigue index
= 45%
