应用斜面仪测定分析细碎化处理后大豆秸秆的滑动摩擦角,为大豆秸秆纤维制取机供料系统的设计提供理论依据。以揉搓粉碎处理后大豆秸秆含水率为试验因素,通过单因素试验研究,分别建立了不同含水率对揉搓粉碎处理后大豆秸秆与不同材料间滑动摩擦特性影响的数学模型并分析其变化规律。结果表明:含水率对滑动摩擦角有显著的影响,随着含水率的增大,大豆秸秆与钢板的滑动摩擦角呈先增大后减小的趋势,与输送带的滑动摩擦角呈增大的趋势。
The slippage angle of soybean straw after the smashing process was analyzed by using the slant meter to provide the theoretical basis for the design of the feeding system of soybean straw fiber. Taking the moisture content of soybean straw as the experimental factor, the mathematic model of different moisture content on the tribological properties of the soybean straw and the different materials after the rubbing smash treatment was established by single factor experiment and the variation regularity was analyzed. The results show that the water content has a significant influence on the sliding friction angle. With the increase of water content, the sliding friction angle of soybean straw and steel plate first increases and then decreases, and the sliding friction angle with the conveyor belt increases the trend of.
