Abstract:
The sliding friction angle of soybean stalk after fragmenting was tested and analyzed with apparatus of incline plane, thereby, a new theory was found for the design of feeding system of soybean stalk fiber extruder. The moisture content of fragmentized soybean stalk was selected as experimental factor, and the single-factor experiment was carried out. Then, the mathematic model was established, which reflected the variation law of moisture content on the sliding friction characteristics between soybean stalk and steel plate and that between stalk and rubber. The result indicated that the moisture content had significant influence on sliding friction angle, with the increasing of moisture content, the sliding friction angle between soybean stalk and steel plate had no significant variation firstly, and then decreased while the moisture content reached to a critical value, and the sliding friction angle between soybean stalk and rubber showed increasing trend.
