Abstract: A promising and efficient way to improve the performance of the machinery is to continuously integrate new technologies into the total life cycle. With the in-depth development of the integration of industrialization and informatization, how to deeply integrate modern information technology with machinery is the key to improving the level of intelligentization of mechanical products. The subject of machinery information proposed in the paper is used to investigate all the dynamic information of the machinery throughout the life cycle, which integrates the disciplines of information technology, mechanics, manufacturing and other related disciplines so as to provide much more detail and abundant information about the performance and it related parameters. The concept and content of the machinery information is also introduced, some examples are given to illustrate how to solve the practical problems based on this theory.

Key words: dynamics, informatics, electromechanical coupling, intelligent manufacturing, intelligent equipment
