A novel aluminum alloy subway train body is characterized in that a train roof edge beam 1-1 is made of large-section aluminum alloy sections, beams and columns of a front end framework structure areformed by assembling and welding square steel, connectors of an end wall framework and end wall plates are fixedly connected in a welded mode to form a frame structure, and side wall window area sections are provided with grooves. The end underframe assembly and the buffer beam assembly adopt high-strength steel plate welded structures, the underframe edge beam, the first-position end beam, the second-position end beam and the floor assembly adopt large-section aluminum alloy sections, two ends of the vehicle body underframe are respectively provided with two energy-absorbing anti-creeping devices made of high-strength steel materials, and the underframe is provided with an energy-absorbing structure end underframe made of high-strength steel materials. The vehicle body meets the requirements of newly developed Shanghai No.6 and No.8 lines, and the structure of the vehicle body meets the performance requirements of strength, fatigue and the like.
