| 초록 |
In this paper, we study the modeling method for a suspension bush with frequency and amplitude-dependent nonlinear dynamic characteristics. The proposed bush model adds amplitude-dependent cells to the generalized Maxwell model, the most general form of force element model for viscoelasticity. A frictional Maxwell model is used as the amplitude-dependent cell in which the damper element is replaced with a friction element in the Maxwell model. We establish a parameter identification process for this bush model and apply it to the front Mcpherson suspension. To verify the accuracy of the proposed bush model at the system level, half-car durability simulation based on multibody dynamics is performed on the suspension model equipped with the bush model. The results are compared with the accuracy of the suspension model using the Kelvin-Voight model, which is commonly used as a bush model. |
