Abstract
∗Hydraulic climbing formwork technology is widely used in largescale construction projects in my country because of its high efficiency. However, as the scale of the project becomes larger, the shortcomings of hydraulic climbing formwork are exposed. Due
to the inconsistent manufacturing precision of hydraulic components and the uneven load of the template due to uneven force, the outer template or guide rail is out of sync during the climbing process, which leads to component damage or deviation in construction accuracy. The hydraulic creeping mold electro-hydraulic proportional synchronization control system designed in this paper can adjust the opening of the proportional flow valve through the synchronous feedback and processing of the position signal of the
hydraulic pump, that is, change the flow rate so that the positions of the hydraulic pumps are consistent, which solves the problem of non-synchronization. Make the outer template and guide rail climb smoothly and efficiently. In this paper, Adams and AMESim
software are used for co-simulation to test the feasibility of the system.
The inner diameter of the hydraulic cylinder is 160mm, and the outer diameter of the piston rod is 125mm. That is, the hydraulic cylinder model is YG-210-160/125
Calculation of cross-sectional area of rod cavity of hydraulic cylinder.
