| Abstract: | The dynamic characteristics of the hydraulic system of the concrete delivery pump are studied. Firstly, the flowing state of the concrete is analyzed by virtue of the nonlinear hydrodynamics, and the equation governing the concrete flowing is established, concerning the frictional force and the concrete flowing speed. Then, the mathematical model of the hydraulic system driving the concrete pump is established based on the theory and method of the power bond graph and the state|space analysis. Finally, the dynamic characteristics of the hydraulic system are simulated numerically,and some significant results are presented. |
