🌐 Virtual world in the factory: Digital Twin
A digital twin is a technology that creates a virtual replica of a physical asset, such as a machine, plant, or entire production line, using real-time data collected from IoT sensors to reflect the physical condition and behavior of the real asset at all times.
💡 Main content: How does a Digital Twin work and what benefits does it provide?
1. The concept of Digital Twin
A digital twin is not just a 3D model, but a system with three main components:
1. Physical Asset: Real machinery, conveyor belts, or plants with IoT sensors installed.
2. Virtual Model: A computer program that recreates the image and behavior of the asset, including simulation of the physics and logic of its operation.
3. Data Link: Real-time data from sensors (e.g., temperature, vibration, performance) is continuously fed into the digital twin, bringing the model to life and reflecting the current state of the real thing.
2. Benefits of Pre-Construction Simulation
Using a digital twin during the design or expansion phase of a plant is a highly worthwhile investment:
Reduce investment risk (Risk Reduction): New machine layouts, production line additions, or process changes can be tested in the virtual world without touching the actual machinery or structure, ensuring that the investment will perform as expected.
Optimization: Use simulation to find production bottlenecks , test optimal operating speeds, or test material transport to achieve the best throughput before actual construction.
Reduced Time-to-Market: All testing and troubleshooting is done virtually, making deployment and commissioning faster and smoother.
3. Case Study: Using Digital Twin to Improve Efficiency and Training
| Usage | Case Study | Benefits received |
| Performance Improvement | Production line simulation | Companies can simulate rare failure scenarios or test workload changes without actually stopping the production line, potentially increasing OEE (Overall Equipment Effectiveness) by several percentage points. |
| Predictive maintenance | Heavy machinery inspection | Engineers use a digital twin to predict the remaining useful life of critical components such as bearings by feeding vibration data into the model, enabling accurate maintenance planning. |
| Personnel training | Technician training | New employees can practice operating complex machinery or practicing troubleshooting procedures in a virtual environment without the risk of damaging real machinery , and can practice it over and over again. |
Digital Twin is therefore an important tool in Industry 4.0 that connects the physical and digital worlds to enable more efficient and intelligent operations.
