摘　　要：Based on the multi-body kinematics principle, the topological structure and restriction relation among parts of machine tool and 3D multi-body model are constructed, the kinematics simulation system of machine tool is developed. The designer can observe the movement and machining course of the whole machine tool and understand accurately the kinematics parameters of components such as position, velocity and acceleration. Also the designer can estimate the pose of components in the virtual circumstance and forecast accurately and correct problems which may appear during the design before the prototype is manufactured to assure the feasibility of design scheme, shorten period of product design and reduce product cost. The simulation system is used during the design of CK1416 high speed and precision numerical control lathe. The curves of ball screw angular velocity and carriage displacement agree well with the results of theoretical calculation and the constructed model is correct.从多体系统运动学理论的角度 ,构建了机床各部件之间的拓扑结构和约束关系 ,建立了三维多体模型 ,开发了运动学仿真系统 .设计者可在虚拟环境下观察到整个机床的运动加工过程 ,准确了解零部件的位置、速度和加速度等运动参数 ,判断零部件的姿态 ,并可在样机试制前对设计中可能出现的问题作出精确的预测和改进 ,保证设计方案的可行性 ,缩短产品的研制周期和降低成本 .该仿真系统用于CK14 16高速高精度数控车床的设计 ,所得到的滚珠丝杆角速度曲线、拖板位移曲线与理论结果一致 ,从而证明了模型的正确性 .
