The invention discloses a ceiling fault surface structure of an urban rail stainless steel vehicle. The ceiling fault surface structure comprises two upper chord beams and a plurality of curved beams which are laterally arranged at intervals on the upper chord beams in parallel, wherein two ends of each of the curved beams are respectively butted against on the positioning surfaces of the upper chord beams; the top surfaces of two ends of each of the curved beams are respectively combined with a side top plate in a clamping manner; a covering surface is arranged on the upper central surfaces of curved beams; the covering surface comprises a corrugated plate region and an arc plate region which are in arc welding connection; an air conditioner platform is arranged in the arc plate region; the top surface of the corrugated plate region and the top surface of the arc plate region are on the same plane. The novel stainless steel ceiling fault surface structure effectively solves the problem of light weight design of a vehicle body structure, the weight of the vehicle body structure per unit length can be reduced by about 20kg, the production technology flows are simplified, and the production efficiency is improved. Material consumption is reduced, so that the material cost is reduced. The number of small built-in steel structure components is obviously reduced, the small components are simple in structure and easy to produce and weld, and a design basis is provided for the novel stainless steel vehicle body structure.
