MTTR prediction

[Bucky88]

Would anyone know where I can get my hands on some MTTR prediction data for mechanical parts??

Is there a such thing as a handbook for this?

HELP!!!

:confused:

You might want to check out the following document from the US Army.

Publication Number: TM 5-698-5
Title: Survey of Reliability and Availability Information for Power Distribution, Power Generation, and Heating, Ventilating and Air Conditioning (HVAC) Components for Commercial, Industrial, and Utility Installations

This document can be found at http://www.usace.army.mil/publications/armytm/tm5-698-5/.

I hope this helps.

Thx for your help...

I know there is actually a database for predicting MTTR, same concept as NPRD-95..

Item Soft uses it in their software.

I'm just wondering if there anyway of purchasing a hard copy of this database.

NSWC-98 Handbook

would anyone know if this is a similar concept to NPRD95 but made to maintenance..

[David]

The NSWC-98 is the same as MIL-STD 217, but for mechanical components. Maintenance is not mentioned in NSWC-98.

I deal with mainly mechanical components - so this should help me then?

[David]

NSWC predicts a system failure rate based on the assumption that all components are arranged in series and their failure times follow an exponential distribution. However, it does not mention maintenance in the standard.

Element data can be obtained from RADC-TR-70-89, Maintainability Prediction and Demonstration Techniques, and MIL-HDBK-470A, Appendix D
