面向运动学动力学求解的产品信息建模

Modeling of Product for Kinematic and Dynamic Analysis

在基于图论的机构拓扑结构表达基础上,通过引入拓扑图之边的权因子来表达运动副类型及运动副位置和姿态信息,建立了机构运动尺度信息;通过产品CAD模型的中性文件建立运动单元的物理特性信息;由产品CAD模型的中性文件提取其运动信息及人机交互建立驱动信息;从而建立了面向运动学动力学求解的产品模型的完整信息。

Based on the graph theory, by introducing a weight of pair type, pair position and orientation, an integrity knowledge model of product for kinematic and dynamic analysis is built. It includes the topological structure, motion dimension, drive information and physical characteristics. The knowledge of topological structure, motion dimension and physical characteristics is derived from its CAD model while the drive information is achieved by interaction between user and machine.
