Assessing the Vibration Fatigue Life of Engine Mounted Components

As part of the design validation of components mounted on rotating machinery such a car engine, it is essential to understand the environmental stress in which they operate. In the case of vibration loadings, the reliability must be verified according to accelerated tests that realistically reproduce the in-service stress. Indeed, a representative validation profile permits not only the assessment of the component durability, but it also provides a reliable reference for design optimization (downsizing), reducing development cycle costs and time scale.
