The VALENIAN rotating machinery fault comprehensive simulation testbed is an advanced platform specifically designed for teaching, training, and scientific research diagnosis. Its core value lies in its ability to highly simulate various common faults of rotating machinery in industrial sites, providing users with a safe, controllable, and efficient environment for fault simulation and analysis.
⚙️ Detailed explanation of core functional modules
The experimental bench, through its modular design, enables users to flexibly combine different fault simulation components for systematic research ranging from single faults to complex coupled faults.
Torque loading experiment: Equipped with loading devices such as magnetic powder brakes, it can simulate the operating state of equipment under different load conditions, including constant torque, variable torque, and even pulse torque. This is crucial for studying the vibration characteristics and performance evolution of equipment such as fans and pumps under real-world operating conditions.
Misalignment simulation experiment: It can accurately simulate shafting misalignment defects such as parallel misalignment and angular misalignment. These defects are one of the main causes of abnormal equipment vibration, bearing wear, and seal failure. Mastering their diagnostic methods is crucial for maintenance personnel.
Unbalance simulation experiment: By installing or removing preset mass blocks on the rotor disc directly connected to the motor, the dynamic unbalance state of the rotor can be accurately replicated. This allows users to intuitively study the vibration characteristics of unbalance faults (especially the strong 1x rotational frequency component) and learn efficient dynamic balance correction techniques.
Rotating shaft rubbing experiment: A specially designed rubbing bracket and rubbing components made of various materials such as brass and nylon can be used to simulate the friction between rotating and stationary components. Such failures generate unique nonlinear vibration signals, and the experimental setup provides conditions for studying their early characteristics and development patterns.
Rolling bearing fault experiment: Provides five pre-set fault bearing kits, including inner ring, outer ring, rolling element, cage damage, and their composite faults. This provides an ideal platform for learning to use advanced techniques such as envelope spectrum analysis to diagnose early bearing damage.
Parallel-axis gear fault experiment: Equipped with high-speed and low-speed spur gear fault components (four sets each), it can simulate actual cases of tooth surface wear. Through this module, one can conduct in-depth research on the vibration spectrum characteristics of gear faults, such as changes in meshing frequency and its sideband.
System Advantages and Comprehensive Application
The excellent performance of this experimental bench has demonstrated its significant value in multiple application scenarios.
Teaching and Training: It serves as an ideal practical platform for courses such as mechanical vibration, fault diagnosis, and condition monitoring. By transforming abstract theoretical knowledge into tangible and observable hands-on experiments, it significantly enhances teaching effectiveness and cultivates students' ability to solve practical problems.
Scientific research and innovation: Provides reliable data sources and verification environments for researchers to develop and validate new fault diagnosis algorithms and predictive maintenance models. It allows for the simulation of the entire process of fault generation, development, and failure on the experimental bench, collecting high-quality multi-dimensional data such as vibration and temperature.
Industrial rehearsal: Enterprises can utilize this platform to train equipment maintenance personnel, enabling them to safely practice diagnostic procedures without affecting production. This enhances their ability to handle real equipment failures, thereby reducing the time spent on troubleshooting and minimizing the risk of unplanned downtime.
The experimental bench integrates a complete measurement and control system, including a multi-channel data collector, an acceleration sensor, and professional analysis software. The software supports various advanced analysis tools such as time-domain waveform, spectral analysis, and envelope demodulation, capable of meeting a wide range of needs from basic teaching to cutting-edge scientific research.
