An Integrated Measurement System for Pyromagnetic Effect of Prefabricated Defects Polymer Materials

Abstract:

There exist multi-field coupling effect in prefabricated defects polymer materials under loading. For understanding the pyromagnetic effect, it is crucial to accurately measure the coupling relations of the key physical quantities about displacement, tensile load, temperature, and magnetic field. To overcome the obstacle in current measurement systems for synchronized measurement, an integrated measurement system for multi-field coupling detection is presented to enable synchronized, automatic detection. This paper introduces the system structure, software design, and the detailed design of varied-speed PID control methods. Test results show that, the system is effective for valid data acquisition for displacement, tension load, temperature and magnetic field of a high polymer Polyvinyl Chloride (PVC) plate sample under constant tensile load, and all test data can be visualized on the software interface. This system provides a good test platform for further research on pyromagnetic effect of PVC plate.
