Support for the Major Reliability Prediction Standards
MIL-217, Bellcore/Telcordia and NSWC (Mechanical)
Lambda Predict supports the major reliability prediction standards* and makes it possible to mix and match components analyzed with different standards when applicable. With the new "Generic" system type, you can even create a single electromechanical system analysis that contains some subsystems analyzed with MIL-217 or Bellcore/Telcordia and others analyzed with NSWC (Mechanical).
MIL-HDBK-217F
Reliability Prediction of Electronic Equipment (MIL-HDBK-217F), issued by the U.S. Department of Defense in December, 1991. This standard provides reliability prediction models for electronic components in commercial and military applications.
Support for Both Part Stress and Parts Count Analyses
In addition to providing full support for the MIL-217 Part Stress calculation method, the software also includes a library database with nearly 3,000 components that can be used to quickly create a MIL-217 Parts Count prediction. This analysis approach may be applicable during bid proposals and early design phases when sufficient information is not available to use other methodologies.
Ability to Define Custom Connections
The software supports the connection types specified in the MIL HDBK standard (e.g. Reflow Solder, Spring Contact, etc.) and also allows you to define your own custom factors that describe the effect of the connection type on the failure rate of the assembly.
Non-Operational Phases
For MIL-217 analyses, the software allows you to specify separate parameters that apply to the item during non-operational phases and automatically calculates the quiescent failure rate.
Bellcore/Telcordia
Reliability Prediction Procedure for Electronic Equipment (SR-332 Issue 2), issued by Telcordia Technologies in September, 2006. This standard provides reliability prediction models for electronic components in commercial applications, including updated component failure rates and the ability to calculate the upper bound for the failure rate at different confidence levels. Lambda Predict also supports two previous versions of the standard: TR-332 Issue 6, issued by Bell Communications Research in 1997 and SR-332 Issue 1, issued by Telcordia Technologies in 2001.
NSWC (Mechanical)
The Handbook of Reliability Prediction Procedures for Mechanical Equipment (NSWC-07), issued by the Naval Surface Warfare Center Carderock Division on July 31, 2007. This standard provides reliability prediction models for mechanical components, such as seals, springs, pumps, valves, brakes and more.
DISCLAIMER: The Lambda Predict software is intended to facilitate the widely used methods that are described in published reliability prediction standards. The software was not developed in cooperation with or endorsed by the organizations that developed and published these standards. ReliaSoft has validated the software against the standards themselves but any issues with the methods described within a standard should be directed to the publishing organization so the feedback may be considered in a future update to the guideline.
