Noise Evaluation Method for Starting Motors of Passenger Cars
摘要
Abstract
Starting motor noise is an important factor for evaluation of the passenger car’s acoustic quality. In this pa-per, an objective evaluation method with order analysis was proposed based on the subjective assessment results of the motor noise. The subjective evaluation of fifteen sample motors was carried out using the ranking scale method. Testing results showed that eight motors of them were acceptable. The highest orders of the acceptable motors were extracted under idle and load conditions to build the key group of critical orders. Then, by extracting the envelope of the critical orders, the threshold for objective judgment of starting motor noise of the passenger car was established. The proposed method may provide an al-ternate choice to evaluate motor noise for passenger cars.关键词
