| Abstract: |
| This paper aims to study the effects of harsh environment on the performance of disaster relief tents. A multi-disaster compound environment experimental platform was established to conduct experimental research on different working conditions of disaster relief tents, and to explore the changes of internal thermal environment distribution and thermal insulation performance of disaster relief tents under different external environments. The results indicated that the stratification of thermal environment occurred only in the temperature rising stage, yet weakened after the addition of wind load. In the descending stage, the temperature changes of each inner surface were basically the same. When the ambient temperature of additional snow load is lower than –10 ℃, the thermal insulation of relief tents becomes poor. The evaluation index system of disaster relief tent coupling environment adaptability was established by value function method, and the evaluation method of disaster relief tent adaptability under wind-low temperature, rain and snow compound environment was proposed, and the evaluation score was verified by the test results. In conclusion, the internal environment of tents under low temperature compound environment is greatly affected by external environment, and thereby the thermal insulation performance is poor with the “cold chamber effect” easy to appear. Therefore, new materials should be actively sought to improve the adaptability of tents under harsh environment. |
