1Measurement precision
If traditional noise monitoring methods are used in an industrial environment with multiple machines, then noise levels can be measured, but it becomes difficult to identify the specific source of noise or vibration
Solution Approach 1:
The system segments the industrial environment into individual machine entities, creating a digital twin for each machine. This segmentation allows the system to attribute noise and vibration sources to specific machines rather than treating the entire environment as a single complex system, thereby improving noise source identification accuracy while maintaining manageable system complexity through modular digital twin architecture.
Solution Approach 2:
The digital twin acts as an intermediary between physical machines and the noise analysis system. It receives operational data from machines and translates it into simulated noise and vibration characteristics, enabling precise noise source identification without requiring direct complex measurements from the physical environment. This intermediary layer simplifies the overall system while improving measurement precision.
2Object-affected harmful factors
If maintenance is performed on machines to reduce noise and vibration, then noise levels can be controlled below threshold, but maintenance costs increase
Solution Approach 1:
The system performs preliminary analysis using digital twins to predict future noise and vibration levels before they exceed thresholds. By simulating machine operation and identifying potential noise issues in advance, the system enables planned maintenance at optimal times rather than reactive maintenance, reducing overall maintenance costs while ensuring noise levels remain controlled.
Solution Approach 2:
The system establishes a feedback loop where digital twin simulations continuously monitor predicted noise levels and compare them against thresholds. When predictions indicate potential threshold violations, the system provides feedback to trigger targeted maintenance actions. This feedback mechanism ensures noise control is achieved only when necessary, optimizing maintenance costs by avoiding unnecessary maintenance while preventing threshold violations.
