供应英国企业提供振动分析技术
欧盟项目创新中心
项目概述
英国一家企业成立于1946年，是一个会员制组织，通过工程、材料和连接技术提供权威的专家建议、专有技术和安全保证，帮助设计、创造和运营最好的产品。
该企业提供振动分析服务，监控振动水平并研究振动信号模式的过程。它通常直接在振动信号的时间波形上进行，也可以在频谱上进行，这是通过在时间波形上应用傅里叶变换获得的。在实际应用中，特别是在旋转机械中，结合时域分析和频谱分析，监测振动水平和检测异常振动模式，评估被监测目标的整体状况以及检查大型旋转设备中齿轮、轴承和轴等关键部件的状况，快速有效地进行频率分析，并助力各种数字噪声滤波器的设计。
振动可以通过各种类型的传感器进行测量。基于不同类型的振动，有设计用于测量位移，速度和加速度的传感器，具有不同的测量技术，例如压电（PZT）传感器，微机电传感器（MEMS），电涡流探头，激光多普勒测振仪等。
振动分析通常应用于机械及其关键旋转部件的状态监测，包括但不限于：
1. 轴承、齿轮、轴、自由轮；
2. 旋转机器，如齿轮箱、电机、风扇和传动系统；
3. 活塞发动机、往复式压缩机、泵和门机构等往复式机器。
优势与创新
1. 对状况变化的实时反应；
2. 支持远程状态监测；
3. 用于预测性维护的成熟处理和信号分析方法/算法；
4. 由各种商用传感器支持，适用于不同的操作条件。
合作模式
拟寻找对此技术感兴趣的合作伙伴，以设备采购、技术合作等多种形式合作。
Project Overview
Founded in 1946, a British enterprise is a membership organization that provides authoritative expert advice, proprietary technology and security assurance through engineering, materials and connection technology to help design, create and operate the best products.
The enterprise provides vibration analysis services, monitors vibration levels and studies the process of vibration signal patterns. It is usually carried out directly on the time waveform of the vibration signal or on the frequency spectrum, which is obtained by applying Fourier transform on the time waveform. In practical applications, especially in rotating machinery, combining time domain analysis and frequency spectrum analysis, monitor vibration levels and detect abnormal vibration modes, evaluate the overall condition of monitored objects and check the condition of key components such as gears, bearings and shafts in large rotating equipment, conduct frequency analysis quickly and effectively, and assist in the design of various digital noise filters.
Vibration can be measured by various types of sensors. Based on different types of vibration, there are sensors designed to measure displacement, velocity and acceleration, and different measurement technologies, such as piezoelectric (PZT) sensors, micro electro mechanical sensors (MEMS), eddy current probes, laser Doppler vibration meters, etc.
Vibration analysis is usually applied to condition monitoring of machinery and its key rotating parts, including but not limited to:
1. Bearing, gear, shaft and free wheel;
2. Rotating machines, such as gearbox, motor, fan and transmission system;
3. Reciprocating machines such as piston engine, reciprocating compressor, pump and door mechanism.
Advantages and Innovation
1. Real time response to situation changes;
2. Support remote status monitoring;
3. Mature processing and signal analysis methods/algorithms for predictive maintenance;
4. Supported by various commercial sensors, it is applicable to different operating conditions.
Cooperation mode
It is planned to find partners interested in this technology to cooperate in various forms such as equipment procurement and technical cooperation.
