The effect of dynamic fatigue loading on the carpet samples subjected to long-time UV radiation exposure has been studied. The carpet samples are first subjected to different UV exposure time and then dynamic loading is imposed to the samples. In each case, the thickness loss of the carpets is measured. The results show that the UV exposure time has a slight effect on the thickness loss of the carpets. The number of dynamic impacts, on the other hand, shows a significant effect on the thickness loss with an exponential correlation. Using best curve fitting method based on least square method, a predicting equation is derived for the multiple effect of UV exposure time and number of dynamic loading on the thickness loss. The experimental verification reveals that the proposed predicting equation can be used with an acceptable accuracy.

多元回归法分析紫外线降解和动态载荷对丙烯酸地毯耐久性的影响

研究了动态疲劳载荷对地毯样品经受长时间紫外线辐射的影响。地毯样品首先要经受不同的紫外线暴露时间,然后将动态载荷施加到样品上。在每种情况下,都测量地毯的厚度损失。结果表明,紫外线暴露时间对地毯的厚度损失影响很小。另一方面,动态冲击的数量对厚度损失具有显着的影响,并且具有指数相关性。使用基于最小二乘法的最佳曲线拟合方法,得出了紫外线暴露时间和动态载荷数量对厚度损失的多重影响的预测方程。实验验证表明,所提出的预测方程式可以以可接受的精度使用。
