Weibull Analysis

Reliability method that models time-to-failure data to characterize failure behavior and estimate life.

Examples

01Weibull analysis of 34 gearbox failures gives a shape factor of 3.1, which points to wear-out rather than random failures.
02Before the replacement interval is set, reliability engineering reviews the Weibull analysis together with the cost of a failure.
03Based on the Weibull analysis, gearboxes are replaced at 18,000 hours, which prevents most failures at acceptable cost.
