【 摘 要 】

In this paper, geometric errors of braking-type plate shearing machine were analyzed based on Multi-body system theory and sensitivity coefficient. The general expression of pose, movement and errors were expressed based on a 6×3200 braking-type plate shearing machine. The mathematic model was built up and the geometric error was identified based on sensitivity coefficient which calculated by first-order sensitivity function and data analysis. The improvement measures were listed to increase machining accuracy of braking-type plate shearing machine according to above theoretical analysis and practical production.
