Durability of the product
Durability is the average economic life of the product. The value of durability is strongly influenced by the demand index of the manoeuvres performed by the
automatism: that is the sum of all the factors which contribute to the wear of the product (see Table 2).
To establish the probable durability of your automatism proceed as follows:
01. Calculate the demand index summing the values in percentage of the entries present in Table 2 to each other;
02. In Graph A, from the value just found, trace a vertical line until you intersect the curve; from this point trace a horizontal line to cross the line of “cycles of
manoeuvres”. The value established is the estimated durability of your product.
The estimate of durability is performed on the basis of the design calculations and the results of tests carried out on prototypes. In fact, being an estimate, it does
not give any guarantee on the actual duration of the product.
Example of calculation of durability of a Toona series 5 gear motor (refer to Table 2 and Graph A):
- leaf weight = 350 kg (demand index= 10%)
- leaf length = 3.5 m (demand index = 10%)
- no other stress elements present
Total demand index = 20%
Durability estimate = 160,000 cycles of manoeuvre
