隔热车辆的车体材料在铁路运输中,不断地努力降低车辆在整个使用期内的维修费用。轻型车辆减小单位能耗的经济性是明显的。另一方面,车辆外包板的厚度现在是按材料的耐腐蚀性来选择最小的允许值,而不是按稳定性和强度标准进行选择的。新造客车包板的厚度,按强度条件,0.8～1.2mm Insulating vehicle body materials In the railway transport, continuous efforts to reduce vehicle maintenance costs over the life of. The economy of light vehicles to reduce energy consumption per unit is obvious. On the other hand, the thickness of the car wrapper plate is now chosen to a minimum allowable value based on the corrosion resistance of the material, rather than on the stability and strength criteria. The thickness of the new passenger package board, according to the strength conditions, 0.8 ~ 1.2mm
