| Abstract: | The analysis of linear and non-linear structure stability of ore cars with the axle load of 40 t is described.The buckling eigenvalue coefficient is obtained in linear calculation.The analysis of multi-load steps is made in non-linear calculation with the geometrical non-linearity and material non-linearity.And the accurate buckling load is obtained.The load-displacement curve and the load-stress curve are used to determine the stability of the carbody structure,and the solution scheme is put forward for the stability of carbodies. |
