| Abstract: |
| The work aims to achieve automatic control of the natural environment-load-stress combined action device for engineering plastics, in order to assess and verify the environmental adaptability of engineering plastic products under the combined action of environment and stress. The control system hardware and software were designed and developed based on PLC and IoT devices. The results successfully simulated the synergistic damage effect of natural environment and external loads on engineering plastic products in two typical atmospheric environments, humid hot ocean and cold climate, and had real-time monitoring and recording of relevant experimental parameters and data. The PLC based control system for the natural environment-load-stress combined action device of engineering plastics effectively ensures the normal operation of the testing device, and achieves in-depth research and objective evaluation of environmental damage to engineering plastic products through real-time monitoring and data recording. |
