Abstract

The invention discloses an on-line monitoring device for the acoustic state of an elastic component of the pipeline. The on-line monitoring device comprises two groups of strain gauges, a junction box, a data acquisition module, a data processing module and a display and control console, wherein the two groups of strain gauges are arranged at two positions; the position I is the circumferential direction of a flange of the outlet side of a vibration-damping adapter, and the strain gauges at the position I are used for monitoring the torsional stress of the vibration-damping adapter and determining the torsional acoustic state; the position II is the axial direction of the pipeline connected to the adapter, the strain gauges at the position II are used for monitoring the axial stress of thevibration-damping adapter and determining the axial acoustic state; the strain of the elastic component of the pipeline obtained by measuring through the strain gauges is transferred to the data acquisition module and the data processing module through the junction box, and is processed by corresponding calculation software to form the acoustic state of the elastic component; and the acoustic state of the elastic component is displayed on the display and control console.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to an online acoustic state monitoring device for elastic elements. Background technique [0002] The acoustic state of pipeline elastic components is mainly characterized by stiffness and mechanical impedance. The pipeline of the ship system adopts a large number of elastic components such as vibration-damping joints and elastic supports for vibration isolation design. The acoustic state of these pipeline elastic components is determined by their stress and Determination of deformation state. Due to the difficulty of on-line measurement and evaluation of the deformation and acoustic state of these elastic elements, it affects the monitoring and control of the ship's acoustic stealth performance. Contents of the invention [0003] In view of this, the present invention provides an online monitoring device for the acoustic state of pipeline elastic ...
