【Abstract】 Based on the basic principle of multi-body system kinematics and combined with 6-DOF motion system,the topological structures and low-order body arrays of multi-body system were discussed.The basic rules of system with error were analyzed,and the composing method of characteristic matrix was put forward.Synthesis volumetric errors of 6-DOF motion system were obtained based on characteristic matrix.This method can offer academic reference for error model and error compensation of other multi-degree motion system.更多还原
