Vehicle swing arm detection method and system

The invention relates to the technical field of vehicle swing arms, in particular to a vehicle swing arm detection method and system. The method comprises the steps that S11, positioning is completed based on the swing arm and a detection system, and a first protrusion on a first positioning conical ring abuts against the outer conical surface of a connecting rod part of the swing arm; s12, based on the fact that the first protrusion abuts against the outer conical surface of the connecting rod part, the first positioning conical ring rotates relative to the connecting rod part; s13, based on the rotation of the first positioning cone ring relative to the connecting rod part, collecting a first abutting force and a first driving torque; step S14, acquiring a first locatable area of the first positioning cone ring; s15, based on the fact that the first positioning conical ring is located in the first locatable area, a first detection head of the first detection part sleeves the end part of the connecting rod p
