Data Collection

Data collection is the framework for a good reliability engineering program. It is necessary to have an accurate and comprehensive system of recording data relating to a product's reliability performance in order to be able to produce meaningful reliability reports. Although the nature of the data collection system will differ based on the type of data being collected, there must be a certain number of common elements in the type of data being collected and the way the information is recorded. This is necessary in order to provide the continuity necessary for developing an accurate assessment of the "cradle-to-grave" reliability of a product.

Basic Concepts of Accelerated Life Testing Analysis

In typical life data analysis, the practitioner analyzes life data of a product's sample operating under normal conditions in order to quantify the life characteristics of the product and make predictions about all of the products in the population. For a variety of reasons, manufacturers may wish to obtain reliability results for their products more quickly than they can with data obtained under normal operating conditions. Instead, they may use quantitative accelerated life tests to capture life data for the product under accelerated stress conditions, which cause the products to fail more quickly.

This article presents an overview of basic concepts in quantitative accelerated life data analysis and some suggestions for additional research on the subject. We assume that you already have a basic understanding of life data analysis concepts. ReliaSoft's ALTA software provides a complete array of accelerated life data analysis tools.

Tool Tips
  • When using the Crow Extended model in RGA, how can a specific classification and mode be converted to another classification and mode?

  • If the x-axis labels overlap each other while viewing the Individual Mode MTBF or Individual Mode Failure Intensity plot in RGA, how can this be fixed without changing the number of failure modes being displayed?
