Evaluation of Behavior of a Composite Bogie Frame with Different Finite Element Modeling Methods

초록

In this paper, the strain distribution of the composite bogie frame has been compared with the experimental data and analyzed to the different mesh element types and modeling method. The bogie frame which is composed of skin and core is evaluated with the different types of element using solid and shell. In case of full shell models, they are analyzed each other according to the modeling method such as merging and tying constraints between the nodes. Because engineer has to reduce the analysis time in the early development period, bracket and bolt were replaced by the kinematic constraints which ABAQUS supports. Finally it was validated with the experimental data.
