Subject: Reliability
Recently I attended one week training programme on reliability engineering. I am working in agricultural tractor industry and I want to take up estimation of reliability of our tractors. Can anybody give information how to procure / obtain, NSWC handbook, FMD handbook and NPRD handbook. Regards Bhanuprakash

The NSWC-98/LE1 Handbook of Reliability Prediction Procedures for Mechanical Equipment, 30 September 1998. This 290 page document consisting of twenty chapters of guidance information with equations, engineering tables and procedures for estimating the reliability of a mechanical design for the intended operating environment. The handbook presents an approach for determining the reliability and maintainability (R&M) characteristics of mechanical equipment. Nineteen basic mechanical components have been identified for which reliability prediction equations have been developed: 1) Seals and Gaskets, 2) Springs, 3) Solenoids, 4) Valves, 5) Bearings, 6) Gears and Splines, 7) Actuators, 8) Pumps, 9) Filters, 10) Brakes 11) Clutches, 12) Compressors, 13) Motors, 14) Accumulators and Reservoirs, 15) Fasteners, 16) Couplings, 17) Slider-cranks, 18) Sensors, 19) Transducers. All mechanical equipment is composed of some combination of these nineteen components, and a designer can utilize the equations to determine individual component reliability and then combine results in accordance with the system reliability diagram to determine total system reliability in operating environment. You must order this document directly by letterhead request to US Navy, Code 291, Carderock Division, Naval Surface Warfare Center, 9500 MacArthur Boulevard, West Bethesda, MD 20817-5700, Phone: 301-227-4383, FAX: 301-227-5991. The cost of the document is $200 (US Dollars). For more information go to:
