摘要： 为降低饲草压捆机的能耗,寻找最佳性价比,结合自行研制的饲草压捆机的现场试验,提出一种新的有关稻草压缩的理论模型,提出了单方向压缩、多方向变化的理念,对其主要借鉴流变学理论中黏弹性体的基本性质进行理论推导．将稻草在压缩过程中的变化划分为5个阶段,解释了稻草在压缩过程中的一些实际现象．指出开式压缩中压缩仓长度接近2 m比较合适,在压实程度大约为8倍时,峰值压强约为0.8 MPa,减少捆绳消耗约1/3,为今后农牧业纤维物料压缩设备的动力设计提供了一定的理论依据．

Abstract: A new theoretical model on pasture compression is proposed to reduce hay baler energy consumption and seek the optimum ratio of property & price by combining field experiment on self-developed hay balers. The idea of unidirectional compressing and multi-directional change was presented and its basic properties by reference to visco-elastics qulities in adopting rheology were theoretically deduced. The hay compressing process was divided into 5 phrases， and some practical phenomena during this process were explained. It was concluded that the optimal length of compressing room was 2 m or so. When compression reaches 8 times， the maximal pressure was 0.8 MPa and bundle ties consumption reduces about one third. This paper provides theoretic basis for design of compressing equipments for agricultural fibre material.
