Magnetorheological Fluid Delay Mechanism Arming Time Reduced-order Model Based on Digital Twin
In order to establish a digital twin of magnetorheological delay mechanism that meets the real-time re-quirements,in view of the complexity and time-consuming problem of traditional flow field simulation calcula-tion,a reduced-order model of the mechanism in fluid field was constructed to realize the rapid prediction of its delay performance.Parametric simulation of full-order finite element model of magnetorheological time-delay mechanism in fluid domain was used as sample data.Based on DOE(design of experiments)experimental de-sign,the response surface method was used to establish the slope model in fluid domain,and the correctness and feasibility of the slope model were verified by the full-order finite element model simulation and high-speed rota-tion equivalent test.The simulation results showed that the traditional flow field and the reduced-order model had the same trend,and the error between them was less than 5%in the inspection condition,but the simulation speed of the reduced-order model was 100 times that of the flow field simulation,the reduced-order model could improve the solution efficiency while ensuring the solution accuracy of the MR delay mechanism model.
