Abstract

This paper introduces a novel approach for predicting magnetorheological (MR) valve pressure drop using deep neural networks. Rather than regressing the pressure drop directly, the proposed methodology predicts magnetic flux densities across different zones of the valve and then uses these predictions to compute the MR fluid’s yield stress and the valve’s pressure drop. The proposed approach can be further deployed for optimization purposes and provides insight into the magnetic field distribution within the MR valve as a function of design parameters. The approach leverages finite element simulations encompassing 125 variations of geometric parameters (gap sizes) and control parameters (electrical currents). A multilayer neural network architecture is tuned by testing 72 configurations of activation functions, numbers of hidden nodes, and layers, with model selection based on mean squared error and R^2. The final model demonstrates high fidelity with R^2 more than 0.98 for both training and testing. By capturing how magnetic flux density varies as a function of design and control parameters, the proposed framework facilitates efficient optimization and design of MR valves without exhaustive simulation. These results underscore the method’s ability to capture the complex dynamics governing MR valve pressure drop and provide valuable insights for valve sizing and performance prediction.
