本文研究多动体力学在机械工程领域的应用，运用多体动力学的模型建立作为基础，主要包含本模型坐标系的建立、模型元素、动力学方程和管理体系的分析等。另外运用了在柔性机械臂振动控制、工业机器人动力分析中多体动力学的应用的实例来说明了它如何应用于机械工程领域中的高精度制造与位置跟随。%This paper researches the application of the multi body dynamics in the field of mechanical engineering. As the foundation, the establishment of the multi body dynamics model mainly includes the establishment of coordinate system of itself, the analysis of the model elements, dynamic equation and the management system and so on. In addition, it takes the control of the flexible mechanical arm vibration and the application of the multi body dynamics in the dynamic analysis of the industrial robot for example to expound how the multi body dynamics applied to the high precision manufacturing and position follow in the field of the mechanical engineering.
