It is usually conducted during the concept and design phase of product development, where test data are not yet available.

Standards based reliability prediction is a methodology for predicting the reliability of a product by using failure rate estimates published in globally recognized standards.

The Overview of the Prediction Module page contains a description of the features available in Reliability Workbench for building a NSWC-98 model.

Electric Motors – bearings, motor windings, brushes, armature shaft, housing, gears The user should be familiar with the equipment and the Handbook so that the correct type and number of sub-components can be included in the model.

Slider Crank – bearings, rods/shafts, seals/gaskets, actuators.

Brakes & Clutches – actuators, bearings, friction materials, seals, springs.

Pumps – shafts, seals, bearings, casing, fluid driver.

Valve Assemblies – poppet/sliding action assembly, seals, springs, solenoids, housing.

Slider-Crank Mechanisms Modeling sub-systems in NSWC Many of the categories of mechanical equipment are in fact composed of a collection of sub-components which must be modeled by the user.

The categories of mechanical equipment covered by the Prediction Module are:

So the result of 0.0217 / 10 6 hours in MIL-HDBK-217 is much higher than the result in Bellcore/Telcordia SR-332. NSWC-98 uses a series of models for various categories of mechanical components to predict failure rates which are affected by temperature, stresses, flow rates and various other parameters.Īccording to the handbook.
