In this paper, a summary of multi-physics coupling of hydraulic system is given. The paper introduces the taxonomy of various coupling relationship and the mainly physics fields in the hydraulic system. And this paper introduces a summary of multi-physics coupling of hydraulic system both within China and abroad. According to some common problems of thermal, cavitati- on, pressure ripple and flow ripple on hydraulic system, this paper analyzes which fields influence on these problems, and briefly introduces the existing multi-physics coupling phenomena of prob- lems. This paper predicts the research trend of these problems, and points out that the mathe- matical model of multi-physics coupling needs to be established in the future research work. stud- ies on the mainly physics fields are involved in hydraulic system when these problems influence hydraulicsystem. Finally, this paper puts forward the research method of multi-physics coupling of hydraulic system.
