| Abstract: | The structure and the importance of the axial rubber pad and elastic side-bearing of the cross-brace three-pieced type fright bogie are introduced.At first,the rubber material is analyzed in theory.Then,the axial rubber pad and elastic side-bearing are analyzed by the nonlinear FEA software Marc.The inner stress which couldn't be achieved by test could be obtained and the stress and displace nephogram of the analyzed object could be showed.Then the stiffness of the component could be calculated indirectly.At last,the results are compared with the experiment and the improving methods are provided. |
