The invention provides a railway vehicle apron board structure and a design method thereof.The railway vehicle apron board structure comprises an apron board body, the apron board body is integrally formed by carbon fibers and a PET foam sandwich, the carbon fibers with high impact resistance serve as an outer skin of the apron board, and the impact resistance of the apron board is improved; meanwhile, the weight of the apron board is greatly reduced and the cost is reduced to a certain extent in a mode of combining the carbon fibers and the foam sandwich structure; the damping fin is adhered to the back of the apron board, so that the sound insulation performance of the apron board is improved, and the vibration and noise reduction functions of the product are realized; the apron board body is integrally formed by the carbon fibers and the PET foam sandwich, and the mode that reinforcing ribs are bonded after a product is formed is abandoned, so that the product and the reinforcing ribs can be better combined, the rigidity of the product is enhanced, and the light weight of the product can be better achieved; the apron board is easy to mount, dismount and transport, and noise generated by a wheel track can be reduced to a certain extent and transmitted into a vehicle.

    本发明提供一种轨道车辆裙板结构及其设计方法,包括裙板本体,所述的裙板本体采用碳纤维和PET泡沫夹芯一体成型,本发明将具有高抗冲击性能的碳纤维作为裙板外蒙皮,提高了裙板的抗冲击性能;同时通过碳纤维和泡沫夹芯结构相结合的方式大幅度降低了裙板的重量和在一定程度上降低成本;本发明采用阻尼片粘接在裙板背部,提高了裙板的隔音性能,实现了产品减振降噪的功能;裙板本体由碳纤维和PET泡沫夹芯一体成型,放弃产品成型后再粘接加强筋的模式,不仅能使产品和加强筋的更好的结合,增强产品的刚性,也能更好的实现产品轻量化;本发明裙板易于安装、拆卸和运输,且能够在一定程度上减少轮轨产生的噪音传递到车内。
