摘要
考虑溜管中混凝土重力与管壁的摩擦力,运用拉格朗日法建立了在重力作用下混凝土在软管溜筒中流变的数学模型,运用牛顿迭代求解,并将计算结果与输送情况作了比较。
A mathematical model for rheology in concrete conveying is established considering the gravity of concrete and the friction against the pipe by means of Lagrange scheme. Newton iteration is exploited to solve the model and the results calculated with this model indicate a generally good agreement with the test results of free falling bodies.
