Structural Health Monitoring of Composite Structures - A simplified explanation of the abstract
This abstract first appeared for US patent application 18074724 titled 'Structural Health Monitoring of Composite Structures
The patent application describes devices, systems, and methods for structural health monitoring of composite structures using an enhanced magnetorheological elastomer (MRE) embedded in an elastomer.
- The device is attached to an object by fitting it around the object, with the enhanced MRE having a folded pattern to enhance its performance.
- The device outputs a voltage signal generated by the enhanced MRE in response to deformation, which is then processed using a Wheatstone bridge, an amplifier, and an analog-to-digital convertor to determine a strain value associated with the object.
Potential Applications:
- Structural health monitoring of composite structures in aerospace, automotive, and civil engineering industries.
- Monitoring of deformation and strain in critical components to prevent failures and ensure safety.
Problems Solved:
- Provides a reliable and accurate method for monitoring the structural health of composite structures.
- Enables early detection of potential issues, preventing costly repairs and downtime.
Benefits:
- Enhances safety by detecting structural issues before they escalate.
- Improves maintenance planning and reduces overall maintenance costs.
Commercial Applications:
- Aerospace industry for monitoring aircraft components.
- Automotive industry for monitoring chassis and body structures.
- Civil engineering for monitoring bridges, buildings, and other structures.
Prior Art:
- Previous methods of structural health monitoring may not provide the same level of accuracy and reliability as the described technology.
Frequently Updated Research:
- Ongoing research focuses on optimizing the design and performance of the enhanced MRE for various applications.
Questions about Structural Health Monitoring of Composite Structures:
- How does the enhanced MRE embedded in an elastomer improve the accuracy of strain measurement compared to traditional methods?
- What are the potential challenges in implementing this technology across different industries and applications?
Original Abstract Submitted
Example devices, systems, and methods for structural health monitoring of composite structures are disclosed. One example method includes attaching a device to an object by fitting the device around the object, where the device includes an enhanced magnetorheological elastomer (MRE) and an elastomer, the enhanced MRE has a folded pattern, the enhanced MRE is embedded in the elastomer, and the device is configured to output a voltage signal generated by the enhanced MRE based on a strain induced on the device in response to deformation. A digital signal is generated based on the voltage signal and using a data processing system, where the data processing system includes a Wheatstone bridge, an amplifier, and an analog-to-digital convertor. A strain value associated with the object is determined based on the digital signal.
