The analysis of vertical uneven stiffness and on-line detection research on railroad switch |
| |
| Abstract: | The uneven of vertical stiffness in track is one of the major flaws of railroad switch.This paper,through the analysis of finite element method on inhomogeneous vertical stiffness of railroad switch,explores that the uneven of vertical stiffness in track have impact on the comfort and safety of operation,the necessity of regulating smoothly,and then proposes the homologous method of on-line detection. |
