产品特点：

PT900旋转机械综合故障诊断仿真测试台旋转机械设备在使用较长时间后其内部零件容易产生机械损伤，就会产生磨损失效，需要对旋转机械如轴承、齿轮箱，转轴的故障类别进行特征挖掘分类和预测。振动信号分析是研究旋转机械故障诊断中应用最为广泛的研究方法，通过采集不同损伤情况的齿轮和轴承等部件，工作过程中的振动加速度信号，应用机器学习手段对信号讲行分类与预测，挖掘故障数据的潜在特征，旋转机械故障模拟测试台，可以模拟重现旋转机械，常见的故障振动信号，让很难提取到早期的故障特征进行重现，出现在随着机器学习技术的发展和完善，研究人员将机器学习模型应用于故障诊断，提高了诊断准确性。

Advanced Mechanical Bearing Gear Fault Simulator Test Bed is prone to mechanical damage to its internal components after prolonged use, leading to wear and failure. Therefore, it is necessary to perform feature mining, classification, and prediction of fault categories for rotating machinery such as bearings, gearboxes, and shafts. Vibration  signal analysis is the most widely used research method in the diagnosis of rotating machinery faults. By collecting  vibration acceleration signals from components such as gears and bearings with different damage conditions during  operation, machine learning methods are applied to classify and predict signals, and potential features of fault data  are excavated. The rotating machinery fault simulation test bench can simulate and reproduce common fault vibration signals of rotating machinery, making it difficult to extract early fault features for reproduction. With the development and improvement of machine learning technology, researchers have applied machine learning models to fault  diagnosis, improving diagnostic accuracy。
