牧草在高密度压捆时的应力松弛研究

Study on StressRelaxation of Hay During Baling Under High Density

摘要: 牧草的应力松弛特性对牧草的压缩工艺、压缩设备以及压缩后牧草产品的质量等均有很大影响。利用高密度捆草机对其进行试验研究，后根据积分理论并借助计算机对试验结果进行分析计算，获得了有关流变参数和本构方程，这对牧草压缩理论的发展及压缩设备的开发以及提高压缩后牧草产品的质量等均有重要的指导作用。

Abstract: The stressrelaxation property of hay has quite effects to compressing process and compressing equipment for hay. The paper studies the stressrelaxation property of hay by experiment,calculation and analysis.Some of the rheological parameters and equations are obtained. It is important for developing the compression theory and equipment design to improve the quality of bale.
