摘要
采用模拟压缩的方法 ,研究了低密度秸秆碎料凸向模压成型的流变特性及主要影响因素。结果表明 ,凸向模压成型时物料充填具有不均匀性和压缩时序性。物料流变以纵向为主 ,横向流变使充填趋于均匀。横向位移受物料形态影响最大 。
Simulation compress is used to study rheological behavior and major affecting factors of low density cornstalk fragment convex molding. Results showed that material filling has inhomogeneity and time sequence, material rheological direction is mainly on longitude, and lateral rheology makes filling tend to homogeneousness. The main effect affected by material feature is lateral displacement, then the loading height and slant angle.
