In this paper, a pumping concrete model was established based on Workbench software. The finite element numerical simulation of the concrete pumping pipe and bracket was carried out by fluid-structure coupling technology. The static and dynamic characteristics of the bracket base under different stiffness during the pumping process were studied. The simulation results show that the method presented in this paper can carry out a more accurate numerical simulation of the force of the pipe bracket. The calculation results show that the best comprehensive effect can be achieved by improving the vibration absorber bracket to alleviate the vibration of the concrete pumping system and reduce the negative influence on the main structure. The research results of this paper have been successfully applied in Lu′an Gaotai community resettlement housing project and other projects.
