| Abstract: | The finite element model of a light electric freight car frame was established by Hypermesh,The stress and displacement distribution of the frame under full load motion and torsion(the front right wheel is suspended)are analyzed.On this basis,through the Optistruct automatic optimization,the lightweight design of the frame,and combined with the requirements of manufacturing cost,the final optimization results are given.After this optimization,the frame weight is reduced from 332kg to 222kg,and the weight loss rate is 33%.The lightweight effect is obvious,The obtained results provide the optimization direction and theoretical basis for the frame design,and the engineering significance is obvious. |
