| Abstract: |
| Objective To establish a model and simulation software for temperature and humidity to predict the microenvi-ronment temperature and humidity of packaging container in storage environment for a period of time, and provide technical support for predicting the performance change of product in container in advance. Methods The relationship between temperature and humidity in microenvironment, packaging materials and environment was analyzed. The temperature and humidity model was established. The simulation was conducted with the finite element method. The simulation model was compared and validated with the measured data. Results Compared with the experimental results, the maximum relation error of temperature simulation results was less than 8%, and the maximum relation error of humidity simulation results was less than 11%. Conclusion The microenvironment temperature and humidity simulation software can accurately simulate the microenvironment temperature and humidity of packaging container with different specifications and long storage time. It has good military and industrial application prospects. |
