| Abstract: | Based on the analysis of compressing study on agricultural fibrous materials at home and abroad, some problems are pointed out. They are: 1. Most of studies of agricultural fibrous materials compressed are made only in a small closed end die. 2. Theoretical study is separated from practice. 3. Some factors affecting compression are not considered overally. 4. Only simple rheological characteristics of agricultural fibrous materials compressed are studied. 5. Meanwhile a constant stress should be given to the compressed materials. Some directions of future studying are pointed out. 1. The creep and relaxation of agricultural fibrous materials during compressing in different charge amount and different compressing frequency. 2. The creep and relaxation of straw pieces and bales at the different position in the chamber. 3. The expansion and tensile stress of a bale when released from chamber. 4. Considering synthetically the factors including pressing force, compressing frequency, charge amount, chamber length, bale length, humidity and power consuming. |
