This paper aims to verify the static strength of a KHST gangway structure including fixed ring and carrying ring according to the load cases in the defined specification. The structure has been analyzed by the finite element method. Calculation carried out in the fields of linearity and small deformation. The admissible limit is the yield strength for the available materials. The analysis results show that Von-Mises stress at some locations of the structure is a little beyond the admissible limit. These results are successfully reflected on the adjusted design.

A FEM-based analytical approach was used to evaluate the static strength and the fatigue strength of a KHST bogie including eddy current brake system. Calculation was carried out in the fields of linearity and small deformation. The yield strengths were used as criteria for evaluating the static strength and the fatigue limits were used as criteria for evaluating the fatigue strength. The analysis results show that there is not any location that exceeds the allowable criteria.
