In order to analyze the dynamic characteristics of the concrete pump closed type hydraulic system in the process of pumping, we add two speed sensors and power units in the system, to achieve the dynamic loading of the pumping load by judging the main oil cylinder speed. We also establish the concrete pump closed type hydraulic system model for the dynamic simulation. The results show that in the process of pumping, pumping pressure keeps constant value and no pressure impact. Meanwhile the piston displacement linearity increases or decreases and the piston velocity keep the constant value.
At present, the ABS braking system has been widely used in vehicle brake system, has become the important mechanism of automobile brake performance. This paper use the advantage of AMESim software for hydraulic system modeling, and build up the the model of ABS for the automobile brake system according to ABS system working principle, Simulation of automobile ABS hydraulic brake system work process, through the relevant parameter settings, compare and analysis the impacts made by some elements of the whole ABS system, finally make the foundations for the brake system for further optimization and improvement.
