| Abstract: | The finite element model of passenger carbody is set up.The critical crack size and crack growth rate of passenger car underframe are calculated with the fracture mechanics.The verification is made through comparison between the finite element analysis and the sidesill deform obtained in the physical loading test.Under certain conditions,the crack analysis process can be applicable to the evaluation of critical crack and crack growth rate for rolling stock. |
