Fatigue Life疲劳寿命
Fatigue life is the expected service duration of a structure or component, measured in flight hours, cycles, or calendar time, before cyclic loading is likely to initiate cracking or failure. In aerospace localization it appears in structural repair manuals, maintenance planning documents, life-limited parts lists, and reliability reports, where it is expressed as a design value and drives inspection intervals and replacement thresholds.

Where this term appears
Translators encounter fatigue life in maintenance schedules, life-limited parts tracking, damage tolerance assessments, and airworthiness directives. It is often presented in tables with units such as flight cycles or hours, so localization must preserve numeric values, unit conversions, and threshold conditions exactly. Multilingual operators rely on these translations to schedule inspections and remove parts before reaching the published life limit.
Translation checks
A common error is translating fatigue life as “service life” or “durability” without the cyclic-loading context, which can blur the distinction between fatigue limits and general wear or corrosion. Another mistake is converting units incorrectly or omitting the reference condition, for example by dropping “flight cycles,” so the stated threshold becomes ambiguous and may lead to premature or overdue replacement.
Keep the term aligned across your files
Check procedure sequence, part names, limits and cautions against the supplied references. Applicable aviation or market requirements depend on the product and project pathway.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
