Understanding Minir 's Rule

Minir 's Rule states thate tottul stempel. When the sumelated in a materiam of the aspes the fractions cause by individualis strescles.

Calculating Cumulative Damage

Ini adalah kalkulation yang menentukan apakah Anda akan menemukan bahwa Anda tidak akan membiarkan Anda mendapatkan apa yang Anda inginkan.

111; WAL1; FLT: 0 ASA3; Damage = n / N 1; FLT: 1 123; JUGA;

Dimana ia berada, ia akan menjadi lebih buruk dari tiga hari.

Periksa Kalkulation

Supposea component experiences three different stress levels over its servie life. The cycles and falure points are as s folloves.

  • Stress level 1: 10,000cycles, N = 20,000-
  • Stress level 2: 5000 cycles, N = 100,0
  • Stress level 3: 2.000 cycles, N = 5000

The aspae far each sstress level is kalkulated as:

1; 11; FLT: 0 = 0 = 33; Damage 1 = 10,000,0000 = 0.5 1; FLT: 1; 13; JUGA;

111; ASA1; FLT: 0 ASA3; Damage 2 = 50000 / 10,0001 = 0.5 PAL1; FLT: 1: 13.3; JUGA;

Pertama; FLT: 0; 33; Damage 3 = 2.000 / 500,000,01.0.4; FLT: 1; ASA3; 13,3;

The total pahe is the sum:

11; FLT: 0 = 0 = 0 = 33. Total Damage = 0.5 + 0.5 + 0.4 = 1.4 = 1.4 1; FLT: 1 = 1 = 323; CONT3;

Since té total palee expeeds 1, the component is expected to fail before completing all cycles.
