AI Technical Summary

Technical Problem

In the existing technology, the sound field assessment of marine pump equipment is not accurate enough, mainly because the physical parameters of the blades are difficult to measure directly and vary greatly in harsh environments, and the arrangement of acoustic sensors is limited, resulting in a large assessment error.

Method used

By selecting several candidate parameter values ​​within the parameter threshold range of the blade's physical properties, and combining the measured sound field intensity measured by the acoustic sensor deployed on the volute, the target error between the theoretical sound field intensity and the measured sound field intensity is calculated. The candidate parameter value with the smallest target error is selected as the target parameter value for sound field evaluation.

Benefits of technology

It improves the accuracy of sound field assessment, ensuring that the target parameter values ​​are closer to the true values, thus enhancing the accuracy of sound field assessment.

Abstract

This invention provides a sound field assessment method, apparatus, electronic device, and storage medium. The method includes: acquiring parameter values ​​corresponding to input condition parameters for sound field assessment, the input condition parameters including pump internal structure property parameters, and the parameter values ​​corresponding to the pump internal structure property parameters including target parameter values ​​corresponding to blade property parameters; obtaining sound field simulation analysis results based on the parameter values ​​corresponding to the input condition parameters, and performing sound field assessment through the sound field simulation analysis results; the target parameter value is selected from several candidate parameter values ​​within the parameter threshold range corresponding to the blade property parameters, based on the target error between the theoretical sound field intensity and the measured sound field intensity corresponding to each candidate parameter value. Thus, by fusing the measured sound field intensity measured by acoustic sensors with the theoretical sound field intensity corresponding to each candidate parameter value within the parameter threshold range corresponding to the blade property parameters, the accuracy of the sound field assessment is improved.
