<Calculation of variation in detected axial force or its average value>
If the detected axial force is f and its reference value is fr, the variation in detected axial force f = f1, f2,..., Fn is ± Δf (= ± Δf1, ± Δf2,... ± Δfn). ,
± Δf1 = f1−fr (1)
± Δf2 = f2-fr (2)
...
± Δfn = fn−fr (3)
Find more.
The average value of the detected axial force f (= f1, f2,..., Fn) is fa, and the added value of the detected axial force is
n
Σ fi = f1 + f2 + ... + fn (4)
i = 1
Then, for example, the average value fa of the addition average of the detected axial force f is
fa = (f1 + f2 +... + fn) / n (5)
It becomes. If the variation of the average value fa of the detected axial force f is ± Δfa, the variation ± Δfa is
± Δfa = fa−fr (6)
Find more.
For example, the variation ± Δf of the detected axial force or the variation ± Δfa of the average value of the detected axial force may be set to ± Δf = 15% and ± Δfa = 15%, for example.
The reference value fr may be changed step by step at a constant value, a constant range, or a tightening stage.
