Mobile-type sensor installation auxiliary platform for measuring sound intensity level of equal-height curved surface

Abstract

The invention discloses a mobile-type sensor installation auxiliary platform for measuring the sound intensity level of an equal-height curved surface, and the platform comprises a bottom plate, a work panel, two guide rails, and a cantilever beam. The bottom plate is provided with two parallel guide grooves, and two ends of the guide rails are provided with rollers. The rollers at two ends of theguide rails are disposed in the two guide grooves. Two ends of the work panel are respectively placed on two guide rails through sliding blocks, and a positioning device is disposed between the sliding blocks and the guide rails. The height of the cantilever beam can be adjusted, and an end part of the cantilever beam is provided with a clamping head. The clamping head is connected with a sound intensity probe, and the sound intensity probe is located above the work panel. The platform can independently move in three directions: X, Y and Z, achieves the precise measurement of the sound intensity levels of equal-height curved surfaces of measured objects in different surface shapes, is simple in structure, is low in manufacturing cost, is convenient to use, and is high in measurement precision.

Description

technical field [0001] The invention belongs to the technical field of sound intensity level detection equipment, and in particular relates to a mobile sensor installation auxiliary platform for measuring the sound intensity level of a contoured surface. Background technique [0002] For modern machinery manufacturing enterprises, the production of rotating machinery parts such as motors often produces large noise due to their structure or assembly, which seriously affects product quality and causes noise pollution in the operating environment. In order to reduce the operating noise and improve the quality of the product, it is necessary to test the sound intensity level of each part of the product structure to obtain the distribution cloud map of the sound intensity level and find out the distribution law of the noise, so as to improve the structure in a targeted manner Optimization has achieved the purpose of reducing noise. They often measure by installing multiple sound...

Problems solved by technology

However, a single sound intensity probe is used to manually scan the surface of the machine for measurement. Although this method has a simple structure and low cost, it cannot measure the constant distance between the microphone and the machine surface.
