Abstract: Gas foil bearings are widely used because of their high speed, no pollution, and long operating life. Today’s
gas foil bearings have developed into the fourth generation multi-leaf air foil bearings. Multi-leaf air foil bearings have
good characteristics due to the mutual overlap of the top foils to generate preload force, the bump foil provides elastic
support, and combined with the surface coating. This paper studied the static and dynamic characteristics of multi-leaf
air foil bearings through experimental methods, static characteristics and dynamic characteristics experimental benches
were designed and built, respectively. The static characteristics experiment analyzed the static loading force and
displacement hysteresis curves of the multi-leaf air foil bearing to obtain the stiffness characteristics of the bearing. The
dynamic characteristics experiment obtained the stiffness and damping characteristics of the bearing through two
methods: time domain and frequency domain analysis. In addition, the effects of different frequencies, different
