Calculate minimum detectable unbalance (Umin) and achievable balance grade for soft or hard bearing balancing machines per ISO 21940-21 (formerly ISO 2953).

Kiwango Cha Mzunguko Usiozingatiwa Ambacho Kinaweza Kugundulika
Kiwango cha mzunguko usiozingatiwa (Umin) cha mashine ya usawa inategemea heshima ya sensorer, ngazi ya kelele ya elektroniki, na azimio la kionyeshi:
Daraja La Usawa Inayokaa
Ambapo ω ni kasi ya angular kwa service speed (si kasi ya usawa).
Kanuni ya vitendo: Umin should be well below the permissible residual unbalance (Uper) — typically no more than about 10% — so that measurement uncertainty does not dominate the result. Balancing machines themselves are described and evaluated per ISO 21940-21 (formerly ISO 2953), which defines the minimum achievable residual unbalance (Umar) and unbalance reduction ratio (URR) tests.
Vyombo vya usawa vya kubebea kwa wataalamu vinavyofanikisha G0.4 hadi G6.3 mahali pa kazi. Inatumika katika nchi za 50+.
