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 ...

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 ...

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, ...
