Here’s a way to calculate the reliability for designs with several subsystems. • Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

Most products are built to specifications that include some measure of reliability. In the design stage, FEA does a good job of pinpointing the weak spots in parts and assemblies. But the real test ...

This paper presents, in a case study format, a methodology for combining the methods of Design of Experiments, Accelerated Testing, and Weibull Analysis to improve the reliability of an ABS ...

Due to widespread improvements in the manufacturing and testing of tantalum capacitors, AVX’s new Q-Process hopes to replace the Weibull Reliability Assessment as the industry standard. The process ...

A Weibull reliability analysis of a repeated pump problem at Chevron Corp.'s Pascagoula, Miss., refinery helped the company identify the failure mode and improve reliability. Rather than accepting the ...

One-shot devices, which are engineered for one-time use and are often subject to destructive testing, represent an important class of critical components in areas ranging from aerospace to biomedical ...
