3.2.1 Product durability
The product’s durability is its average economic life value and is
strongly inuenced by the degree of severity of the manoeuvres:
in other words, the sum of all factors that contribute to product
wear.
To estimate the durability of your automated device, proceed
as follows:
1. add the values of the items in “Table 3” relative to the
system’s conditions
2. in the graph shown in “Figure 2”, from the value obtained
above, trace a vertical line until it intersects the curve;
then, trace a horizontal line until it intersects the line of the
“manoeuvre cycles”. The value obtained is the estimated
lifetime of your product.
The durability values shown in the graph can only be obtained
if the maintenance schedule is strictly observed – see the “
PRODUCT MAINTENANCE” chapter. The durability is estimated
on the basis of the design calculations and the results of tests
effected on prototypes. Being an estimate, therefore, it offers no
explicit guarantee of the product’s actual useful life.
Example of durability calculation: automation of a gate with
a 6.5 m-long leaf weighing 450 kg, installed near the sea
“Table 3” shows the “severity indices” for this type of installation:
10% (“Leaf length”), 20% (“Leaf weight”) and 15% (“Presence of
dust, sand or salt”).
These indicators must be added together to obtain the overall
severity index, which in this case is 45%. With the value
identied (45%), look at the horizontal axis of the graph (“severity
index”) and identify the value corresponding to the number of
“manoeuvre cycles” that the product can perform throughout its
lifetime – roughly 200,000 cycles.
