Description
技术领域technical field
本发明属于声强级检测设备技术领域，具体是涉及一种移动式测量等高曲面声强级的传感器安装辅助平台。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.
背景技术Background technique
对于现代机械制造企业来说，生产电机等旋转机械零部件产品，由于其结构或装配原因往往会产生较大的噪音，严重影响产品质量，造成运行环境噪声污染。为了降低运行噪声，提升产品的品质，需通过对其产品结构每个部位进行声强级测试，以得到声强级的分布云图，找出噪声的分布规律，从而有针对性的对结构进行改进优化，已达到减少噪音的目的。他们往往通过在产品的表面安装多个声强探头来进行测量，其中声强探头包括放大器、间隔器、传声器，但由于声强探头价格昂贵，加上有些产品结构表面复杂，如电机表明往往为曲面形状，要得到准确等距曲面声强测量很难。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 intensity probes on the surface of the product. The sound intensity probes include amplifiers, spacers, and microphones. It is difficult to obtain accurate equidistant surface sound intensity measurements due to the shape of the curved surface.
目前对声强级的测量大多数都是采用手动扫描法，手动扫描法就是通过手柄连接单个声强探头来进行测量。然而用单个声强探头通过手动扫描机器表面的方式来进行测量，而这种方式虽然结构简单、成本较低，但是不能实现传声器与机器表面恒定距离的测量。因此，设计一种可移动式测量等高曲面声强级的传感器安装辅助平台，对采集被测物的声强级数据以及掌握其噪音分布规律显得尤为重要。At present, most of the measurement of the sound intensity level adopts the manual scanning method, and the manual scanning method is to measure by connecting a single sound intensity probe through the handle. However, a single sound intensity probe is used to manually scan the machine surface 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. Therefore, it is particularly important to design a movable sensor installation auxiliary platform for measuring the sound intensity level of the contoured surface to collect the sound intensity level data of the measured object and grasp its noise distribution law.
