Squeeze film damper (SFD) is a commonly used vibration reduction device in rotating machinery such as aero-engine. With the development of aviation science and technology, many new structures of SFD have been derived and developed. The categories of new structural squeeze film dampers from the aspects of structural characteristics, vibration reduction characteristics, vibration reduction effects, and application situations were summarized. Besides, the current research status of new structural squeeze film dampers in China in recent years were also summarized. The shortcomings of current research on new structural squeeze film dampers were pointed out, and an outlook of proposes directions and prospects for future research on new structural squeeze film dampers was made. Besides,the application prospects of new structural squeeze film dampers were pointed out. The results provides a reference for the application and selection of new squeeze film dampers in the vibration reduction design of rotor systems in rotating machinery such as aero engines.
