目的 研究救灾帐篷性能受恶劣环境的影响。方法 建立多灾复合环境试验平台,利用其平台开展救灾帐篷不同工况下的试验研究,探究不同环境下救灾帐篷内部热环境分布和保温性能的变化。结果 帐篷内部热环境分层现象只发生在温度上升阶段,而在附加风载后,分层现象减弱,在下降阶段,各内表面温度变化情况表现基本一致,当附加雪载环境温度低于–10 ℃时,救灾帐篷的保温性变差。利用价值函数法建立了救灾帐篷耦合环境适应性评价指标体系,提出了风&低温、雨雪复合环境下救灾帐篷适应性评价方法,得出评价得分,并与试验结果相印证。结论 低温复合环境下,帐篷内环境受外界影响较大,保温性能不佳,易出现“冷室效应”,应积极寻找新型材料改善帐篷在恶劣环境下的环境适应性。 |

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. |
