NSWC Mechanical Reliability Prediction
The NSWC module of ITEM ToolKit uses a series of models for various categories of mechanical components to predict failure rates based on temperature, stresses, flow rates and various other parameters. It provides models for various types of mechanical devices including actuators, springs, bearings, seals, electric motors, compressors, pumps, brakes and clutches and many more. NSWC is currently the only one of its kind.
Due to the wide range of failure rates that occur in apparently similar components, the NSWC Mechanical Prediction module does not rely on failure rate data alone. It also accounts for material properties, operating environment, and critical failure modes at the component level.
The NSWC 11 (98/LE1, 06/LE10) Standard is a commonly used model for mechanical components. Standard procedures for predicting the reliability of mechanical components, sub-systems and systems are defined in the Naval Surface Warfare Center Handbook of Reliability Prediction Procedures for Mechanical Equipment.
The NSWC Handbook
The "Handbook of Reliability Prediction Procedures for Mechanical Equipment" contains twenty-three chapters of information with equations, engineering tables and procedures for estimating the reliability of a mechanical design for the intended operating environment. Handbook procedures are used to determine the reliability of fundamental components such as springs, bearings, seals and gaskets. These component applications are then expanded to subassemblies such as valves, actuators and pumps and then to the system level. Equations in the Handbook include parameters for material properties, operating conditions and stress levels at each equipment indenture level providing a full reliability, maintainability and availability analysis at the system, assembly and component indenture levels.
The handbook covers the following types of mechanical components:
