A new evaluation method for the mechanical models of magnetorheological damper was proposed. A three-dimensional evaluation index system was established, incorporating statistical parameters, hysteresis curve shape, and model computational efficiency. Seven secondary evaluation indexes were selected to overcome the limitations of single-dimensional assessment. To address the constraints of traditional subjective weighting methods, a combined weighting strategy integrating the entropy weight method and the coefficient of variation method was adopted. The comprehensive weights of secondary evaluation indexes were determined through linear weighting integration. A multi-level evaluation matrix was constructed based on fuzzy comprehensive evaluation theory, while the analytic hierarchy process was applied to determine the weight coefficients of first-level evaluation indexes. The overall evaluation value of the model was subsequently calculated via weighted synthesis. Based on dynamic characteristic tests of magnetorheological dampers, parameter fitting and performance evaluation were conducted for both the Bingham and magic formula models. Results demonstrate that the proposed method enables quantitative decoupled assessment across statistical parameters, hysteresis curve shape, and computational efficiency.
