Reliability modeling and analysis on automotive alternators

With advances of automotive technologies, the electrical devices are increasingly applied for vehicle systems, so that the alternator working environment and loading become tougher. As a result, the alternator working reliability impacts much on vehicle reliability and driving safety. By applying the traditional reliability theories and existing electronic units for alternator reliability research, a series model is established based on the component and part stress analysis and prediction.
