Abstract：Statistical energy analysis(SEA) is used to analysis the vibration characteristic of automobile alternator in this paper. Statistical energy analysis model is established. Coupling loss factors and internal loss factors are analyzed and calculated. Then, loss factors are measured by experimental method, and the sound powers are predicted. From the point of statistical energy analysis, to study on the method for reducing radiated acoustic power of system, there are great practical value and important theoretical significance in the design process of low noise claw pole alternators.
