典型环境中三种自然环境加速试验方法的环境强化效果分析

Analysis on Enhanced Environmental Effect of Three Different Natural Environmental Accelerated Test Methods in Typical Environment

目的研究自然环境加速试验方法的环境强化效果。方法通过分析实时监测获得的典型环境不同自然环境加速试验装置中,温湿度环境因素变化数据,找出典型环境中不同自然环境加速试验装置内部的温湿度环境因素变化规律,计算得到典型环境中不同自然环境加速试验方法对温湿度环境因素的强化效果。结果得到了典型环境中不同自然环境加速试验装置的特征温湿度变化规律曲线图。结论玻璃框、黑箱、强制通风玻璃框等3种自然环境加速试验装置对自然环境的光照热效应有明显的强化作用,其内部温度变化梯度大小与环境中太阳辐射量大小相关。

Objective To study the enhanced environmental effect of natural environmental accelerated test methods. Methods A change rule of humiture environmental parameters was found out through analyzing the variation of humiture environmental parameters which were real-time monitored by different natural environmental accelerated test devices in typical environment, and the enhanced environmental effects of different natural environmental accelerated test methods in typieal environmenl were analyzed by calculating Ihe hnmiture environmental paramelers. Results A hnmiture changing rule graph of different natural environmental accelerated devices was obtained. Conclusion Under-glass Exposure, blackh box exposure and forced ventilation glass box had obvious strengthening effects on illumination heat, and the inner tmperature variation gradient was related to the sun radiation amount in the environment.
