Construction of a Evaluation Model for Interior Sound Quality of Pure Electric Buses Based on Principal Component Regression Analysis
This paper takes the 11 samples of interior noise in pure electric buses as the research object,re-duces the dimensionality of objective parameters by principal component analysis method,and then uses the reduced principal component as independent variables and subjective evaluation results as dependent varia-bles to construct a multiple linear regression prediction model.The results show that the average relative er-ror of the model is 4.6%,and the prediction results are reliable.
