Multipoint Vibration Response Prediction under Uncorrelated Multiple Sources Load Based on Elastic-Net Regularization in Frequency Domain

In order to solve the problems of large number conditions at inherent frequencies and low prediction accuracy when using multiple multivariate linear regression methods for vibration response alone, an elastic-net regularization method is proposed. Firstly, a multi-input multioutput model multipoint frequency domain trained historical data each point. Secondly, under point improved by elastic regularization. Finally, used in working situation. The predicted on experimental dataset cylindrical shell acoustic showed that improvement can better improve reduce some frequencies.
