A universal inspection method for measuring the dimensions of various bogie frames

To address the issues faced by urban rail transit vehicle maintenance enterprises, this includes reliance on manual measurements and limited measurement dimensions. It also tackles the lack of efficient and universal detection methods for multi-type bogie frames. A universal detection method for measuring the dimensions of various steering frame structures was proposed, and a corresponding universal detection platform was designed. The platform mainly consists of an articulated arm coordinate measuring machine and a universal support and fixing platform for the frame, capable of providing universal support, fixing, and full-size measurement for different types of frames. By this platform to measure the typical dimensions of a certain model of frame and comparing the actual measurement results with the factory drawings, the maximum error is 0.77‰, aligning with design specifications and industry standards.
