机电一体化研究的主要目的在于如何更好地实现机电一体化集成.作者在光电数控火焰切割机系统的研制过程中,创造设计了一种信息流图来描述和评价机电一体化集成.信息流图是建立在机械电子学模型的基础上,通过引进信息控制单元模型,并经适当地组合和扩展所形成的一种信息流模型.这种模型适用于机器人、数控机床等机电一体化集成系统的描述,并获得了较好的效果. The main purpose of the mechatronics research is how to achieve the integration of mechatronics better.In the process of developing the system of electro-optical CNC flame cutting machine, the author created and designed an information flow diagram to describe and evaluate the mechatronic integration The figure is based on the mechanical and electronic model, through the introduction of information control unit model, and the appropriate combination and expansion of the formation of an information flow model.This model is suitable for robots, CNC machine tools and other integrated mechatronic system The description, and get better results.
