A new cross-section layout method and geometrical parameter optimization for floor beams of rack car body considering modal factors

Reducing the weight of floor beams is a promising way to carry out the lightweight design of the rack car body. However, the reduction will generally amplify the vibration of the car body chassis transmitted to the floor and cause a decrease in riding comfort. Moreover, the lightweight design of the...
