Modal Analysis of Acoustic Acquisition Probe for Water Supply Pipeline
摘要
Abstract
In order to improve the reliability of sound signal acquisition in water supply pipelines,research was conducted on acoustic acquisition probes based on modal analysis technology.Firstly,the vibration signal of the water supply pipeline is collected using a three-axis accelerometer to evaluate the vibration excitation of the acoustic acquisition probe;Then,using SolidWorks and ANSYS Workbench software,establish a dynamic model of the acoustic acquisition probe and obtain its vibration mode;Finally,based on the vibration excitation and modal analysis results of the acoustic acquisition probe,its structure is optimized by increasing the bottom thickness of the cavity inside the acoustic acquisition probe,improving its natural frequency,avoiding resonance between the acoustic acquisition probe and the water supply pipeline,and ensuring the reliability of sound signal acquisition.关键词
