The invention discloses a rail transit vehicle chassis structure and a machining method of the rail transit vehicle chassis structure. The rail transit vehicle chassis structure comprises a sleeper beam, a traction beam, a floor, an edge beam and an end beam. The end beam middle section and the sleeper beam middle section are welded to the floor through the traction beam, and the end beam edge and the sleeper beam edge are connected through welding of the two sets of edge beams. A welding seam between the traction beam and the sleeper beam is a single V-shaped welding seam. A reinforcing rib is arranged on the traction beam, and a welding seam between the reinforcing rib and the sleeper beam is a Z-direction welding seam. A torsion bar seat installation face is arranged at the welding position of the sleeper beam and the edge beam, and the number of the torsion bar rivet pulling holes in the torsion bar seat installation face is 12.
