3D打印混凝土流动度稳定控制策略设计
Design of flow stability control strategy for 3D printed concrete
摘要
Abstract
The stable control of the flowability of 3D printed concrete is significant for improving the forming quality of printed components.The existing approaches to improving printing accuracy mainly focus on the optimization of concrete material properties,the mechanical structure optimization of printing equipment,and the optimization of printing process parameters.But in fact,whether the flowability of concrete is stable or not directly affects the printing quality.Therefore,from the perspective of control,the relationship between the flowability of concrete and the printing accuracy was analyzed first,and the flow stability control system structure for 3D printed concrete was proposed.Then,a PID(proportional-integral-derivative)control strategy based on PSO(particle swarm optimization)algorithm was designed,which could achieve multiple real-time online optimizations of control parameters and improve the stable control performance of 3D printed concrete flowability.Finally,the feasibility and superiority of the designed PSO-PID control strategy were verified through simulation analysis and printing experiments.The simulation results showed that the PSO-PID control strategy could meet the stable control requirements of concrete flowability.The printing experiments indicated that the PSO-PID control strategy could ensure the continuous and uniform extrusion of concrete,effectively improving the forming accuracy of printed components.The proposed method achieves the stable control of concrete flowability by real-time control of mechanical parameters,which can provide technical support for the engineering application of 3D printed concrete technology.关键词
