| Abstract: | Based on the basic principles of multi-body system kinematics and a Appropriation NC machine tool as an example,after the topological structures of mullti-body systems and their low-order-body arraws are expatiated,the composing methods of characteristic matrixes are put forward in the paper.Besides the above,the basic rules of having-error kinematics of multi-body systems are analyzed and some kinds of arithmetic to obtain synthesis volumetric errors based on characteristic matrixes are researched. |
