摘　　要：分析了牧草在不同初始密度下的应力松弛时间,针对牧草在高密度压捆过程中应力松弛规律,提出了根据牧草第1应力松弛时间确定高密度压捆机压缩频率,为合理选择高密度压捆机的压缩频率提供了一种新方法。并以此确定了不同初始密度下高密度压捆机的压缩频率范围。The stress relaxation times of hay are analyzed at different initial densities, and which are compared with the experiment results of the stress relaxation regulation of hay compressed in high density. The idea to select the compressing frequency of balers is put forward, and the compressing frequencies of balers in high density are calculated at different feed rate which provided a new method for selecting the compressing frequencies of balers in high density.
