近年来,我国南方林下经济产业取得了蓬勃的发展,提供了大量绿色林产品、农副产品。通过研究南方林下饲用植物在加载阶段和保压阶段的蠕变特性,可以揭示林下饲草在受压时的变化规律。分析压缩力对保压阶段草物料蠕变特性的影响,可以得出产品密度的变化趋势。本文对不同压块压强及不同压块温度下的南方林下红薯藤与百喜草压缩蠕变过程进行了研究,发现[M]|[N]流变模型能较好的拟合蠕变过程,利用Origin7.5进行拟合,拟合曲线与实验曲线的决定系数(R~2)均在0.95以上,得到了不同压块压强和不同压块温度下红薯藤与百喜草的压缩蠕变本构方程。并进一步推导出了红薯藤与百喜草在一定应变条件下的松弛曲线。...

With the rapid development of China＇s national economy and social progress, the industry of understory economics in the south of China has been flourishing. By studying the creep characteristics of the materials in the loading stage and the holding stage, we can reveal the changing laws of the materials inside. If the effect of compressive stress on creep characteristics of grass materials will be analyzed, the trend of the product density can be obtained. This paper studied the creep process of understory sweet potato vine and bahia grass in ...
