最大数量坐标法在切削加工运动仿真中的应用

Application of the Most Coordinate Method to the Kinematic Simulation forthe Working Device of Machining

本文立足于多刚体系统计算机仿真理论，对切削加工工装进行了多刚体系统模型简化，建立了包括旋转铰约束、滑移铰约束和附加驱动约束在内的约束方程，并对求解位移非线性方程、线性广义速度方程和线性广义加速度方程的过程进行了分析，编制了用于分析工作装置运动特性的仿真软件，并以典型的切削加工工装作为实例，对其运动特性进行了仿真。

The Kinematic model of the working device for machining is established based on the simulation theory of the multi-rigid-body system,Eguations are derived including those for the revolving joint constraint, the translational joint constraint and the additional driving constraint. The solving processes are analyzed for the nonlinear eguation of position, the eguation of generalized velocity and the eguation of generalized acceleration. A software for simulating the device is programmed. The characteristics are simulated of a typical working device for machining by means of exemplification.
