摘　　要：顶盖是机车车体的重要组成部件,是吊装机械间大部件的通道。同时它还具有对机车机械间顶部进行密封、承载车顶电气和通风设备、保温隔热等功能。通过对近年国产电力机车顶盖结构的对比总结出双层顶盖的结构特点、设计要点及优缺点,为后续电力机车顶盖设计搭建了良好的技术平台。The roof is the important assembly of car body and the access for hoisting large parts in the mechanical compartment. It is also acted as the seal at the top of mechanical compartment, the load of electrical and ventilating devices and for heat insulation. By comparing domestically structure of locomotive cover in recent years, the conclusion of structural features, design elements, advantages and disadvantages of double deck roof are summarized, which will be a good platform for the later design of locomotive roof.
