基于BP和HBP流变模型的磁流变阻尼器数值模拟与性能分析
Numerical simulation and performance analysis of magnetorheological damper based on BP and HBP rheological models
摘要
Abstract
To solve the problem that the traditional constitutive model was not accurate in expressing the rheological characteristics of magnetorheological(MR)fluid,the rheological characteristics of MR fluid were tested by using the MCR302 rheometer,and the relationship between shear stress and shear rate under different magnetic fields was obtained.Genetic algorithm was used to identify the parameters of Bingham-Papanastasiou(BP)model and Herschel-Bulkley-Papanastasiou(HBP)model.The simulation model was established based on the identification results,and the dynamic characteristics of the MR damper were simulated numerically.A MR damper was designed and processed,and a damping force test platform was built to test the damping force,and the experimental results were compared with the simulation results.The results showed that the identification results of the rheological characteristics of MR fluid by HBP model were in good agreement with the experimental results.The prediction results of the two models were quite different in the dynamic characteristics of the damper,but the prediction consistency of the flow rate was good.The predicted value of damping force based on HBP model was in good agreement with the experiment value.The proposed HBP model could express the rheological characteristics of MR fluid with high accuracy and had good practical value.The research results can provide reference for the selection of mechanical model of MR damper in vibration control field.关键词
