Abstract:
Internal friction angle，cohesion and flow function value are three important flowability parameters of chopped soybean stalk.In order to get the theoretical data for designing straw fiber extruder，direct shear test was used to study the flowability parameters of chopped soybean stalk.Comparing single factor experiment was employed to study the variation tendency and significant level of chopped soybean stalk in different moisture contents.The results indicated that the internal friction angle was closely related to moisture contents.The internal friction angle was smaller when the moisture contents was 75%.With the moisture contents reduced，the internal friction angle of chopped soybean stalk increased firstly，and then decreased.The effect of moisture contents on the cohesion and flow function value of chopped soybean stalk was not significant.
