Application of Order Analysis in the Analysis of Noise in Automobile Alternator

Abstract:

With the increasing request of the comfort, reduce the vibration and noise of automobile AC generator as the industry wide concern. In this paper, based on a type of vehicle alternator speed section of excessive noise problems, using order analysis method on noise generator is analyzed, the main harmonic component generator noise for 36 harmonic components, and determine the maximum value of the resonance speed noise in 1800rpm, 2400rpm, 3400rpm near the motor load state. On this basis, puts forward the corresponding improvement measures to improve the motor, the motor noise value to the manufacturer's standard.
