Hybrid modeling approach for vehicle frame coupled with nonlinear dampers
چکیده انگلیسی

The vehicle frame system comprises frame structure and nonlinear dampers. In order to investigate the effects of frame flexibility and nonlinear hysteresis, a hybrid modeling approach for vehicle frame coupled with nonlinear dampers will be proposed. Before that, a complex model for nonlinear damper is developed consisting of knowledge-based model and support vector machine (SVM) model. The frame structure is modeled by FEM where the SVM complex model of damper is embedded in. Thus a hybrid model for vehicle frame system is established and successfully validated via a dummy vehicle riding in different conditions. The results show that the hybrid model can capture the nonlinear dynamic characteristics accurately. The hybrid model can also provide a basis for structural design with the existing of FEM model.


► We propose a model for vehicle frame considering flexibility and hysteresis.
► The modeling approach possesses advantages of both SVM and FEM.
► The hybrid model captures the nonlinear dynamic characteristics.
► The hybrid model is accurate and meaningful to be a basis for structural design.
