Innovative analysis of the physical-mechanical properties of airport conveyor belts

摘要

The article deals with the application possibility of contactless airport conveyor belt diagnostics using magnetic microwires, which can be used as the sensing elements embedded directly in the material structure without the structural violations during the manufacturing process. The rubber-textile and rubber materials are characterized by many properties that are advantageous for their utilization for the conveyor belt manufacturing. However, they have also some disadvantages. One of the ineligible properties is their hyperelasticity, the sudden creation of the cracks inside the material as a consequence of the overloading, impacts, vibrations, wearing, aging or inherent material defects. This can also influence the magnetic microwires placed inside the material and thus to lead to the damage and malfunction of the diagnostic system. The article deals with the analysis of the physical and mechanical properties of the segments of the conveyor belt with the embedded magnetic microwire and with the utilization possibilities of the microwire-based sensors for the airport conveyor belt diagnostics and maintenance.
