    Abstract
  • Based on material nonlinear theory and local plastic deformation being allowed, structure lightweight design were carried out in order to relieve the mass and increase the load-carrying capacity for heavy haul railway vehicle, which was made of high strength low-alloy steel with strengthening characteristic.The optimization measures to weaken the end-wall and strengthen under-frame structure were taken.Furthermore, the nonlinear stability analysis of the lightening structure was put up using geometric nonlinear theory, and was used to develope an optimization new-type 40 t-axle-load heavy haul gondola car whose total mass is 160 t.Under longitudinal compress load case, the maximum stress is 336 MPa, which is less than the yield stress 450 MPa of Q450NQR1 material, and the critical load of local buckling occurrence is 6 252 kN.Under longitudinal impact load case, some stresses are about 530 MPa located on top side cant and end cant, which are below the limited stress 550 MPa, and the stresses on under-frame are more uniformity than that before the optimization.The strength, stiffness and stability of the car meet the demand of AAR criterion, and the deadweight coefficient is only 0.16.The result shows that nonlinear analysis method is a valid instrument of lightweight design of heavy haul vehicle.
